Poisonous Frog Species: The most poisonous frog in the world. The most poisonous frogs on earth Subspecies and variations

Very often in nature external charm is combined with danger. Animals with their bright colors do not always seek to attract the attention of the opposite sex. In most cases, this is a warning to enemies. This effect is common mainly in amphibians, for example, in poisonous frogs, the bright colors of which literally amaze the eye with their beauty.


Quite often, the bright color of amphibians indicates their toxicity and danger.

Features of deadly amphibians

Frogs are familiar to many as a small harmless creature, croaking loudly on rivers, swamps and lakes. However, not all of these amphibians are so cute and harmless - there are real monsters among them, which are literally life-threatening to meet.

Poison frogs are a species of tropical amphibians characterized by particularly toxic skin secretions that can kill any living creature, including humans and large animals. This feature of the amphibian is due to its diet, consisting of poisonous spiders, ticks, tropical ants, etc.

Poison frogs are characterized by particularly toxic secretions of the skin

Insect poisonous substances that enter the frog's body are converted into its own poison, which is then released through the skin glands of the amphibian. Moreover, these toxic substances absolutely do not harm the amphibian itself, but, on the contrary, make it practically invulnerable to enemies, of which there are plenty in the tropics.

Nature has endowed the most poisonous frogs with very beautiful bright colors. However, such a characteristic feature serves mainly not the amphibian itself, but those around it, telling them that it is dangerous to approach this beauty. Unfortunately, many travelers sometimes do not perceive such signals, which ends up being extremely sad for them.

The most dangerous individuals live in the forests of Central and South America. Poison frogs are most often found in:

  • Venezuela;
  • Colombia;
  • the Guianas;
  • Ecuador.

family of poison dart frogs

Dart frogs are a family of amphibians, the main part of whose species is recognized as the most poisonous frogs on the planet. Amphibians are distinguished by their small size (only from 12 to 25 mm) and a weight of about 2 g. Frogs of this genus are characterized by luxurious colors of their body. Blues, lemons, yellow-blacks, bright reds, oranges are just a few of the shades that poison dart frogs can be painted with.


Dart frogs are recognized as the most poisonous frogs in the world

The sounds made by these amphibians are not at all like the usual croaking, rather they resemble the singing of a cricket or an exotic bird. Dart frogs spend a significant part of their lives on the leaves and branches of trees, hunting for small insects. Small suction cups located on the toes of their paws help them climb the trunks. Thanks to this feature, the frog, like a rock climber, can overcome any vertical surface. Unlike most amphibians, poison dart frogs swim very poorly, and in general they dislike water so much that they even lay eggs on leaves and branches.

These frogs move not by jumping, but by regular steps. In case of danger, they do not run away, but fall into a kind of coma, but more often they show retaliatory aggression, boldly jumping on the enemy.

The most poisonous representatives of dart frogs include:


Dangerous Monkey Frog

Phyllomedusa bicolor is a very large frog belonging to the tree frog family. Widespread in the tropical forests of South America. The upper part of the body of the amphibian is colored light green, while the abdomen can be cream, light yellow or white. The interesting manner of moving the bicolor phyllomedusa along the branches of trees makes it very similar to a monkey or a chameleon, which is why this amphibian deserved its second nickname - monkey frog, or monkey frog.


The manner of movement of phyllomedusa bicolor along the branches of trees makes it very similar to a monkey

Locals idolize this amphibian, believing that the poisonous substance secreted by its skin can heal any disease. So, the natives believe that the poison of the phyllomedusa, which has entered the human body, is able to drive away bad energy, thereby returning good luck, endurance and lost male sexual qualities. Often, toxic mucus is used to heal snake bites, as well as treat yellow fever, malaria, etc.

They extract frog poison in a very interesting way: they stretch it by its paws (in the shape of X), and then spit on its back 3-4 times, thereby irritating the phyllomedusa, which immediately begins to secrete the necessary secret. Next, the poison is collected with a wooden spatula, and the amphibian is released into the wild.


Aborigines believe that phyllomedusa poison, which has entered the human body, is able to drive away bad energy.

The method of using toxic mucus is also quite unusual: on the right forearm of a native, several small burns are applied with coal from a fire, after which these wounds are abundantly smeared with the resulting substance. The toxic effect is manifested almost immediately: the heartbeat increases, the pressure rises, then dizziness, nausea and vomiting begin. Some lose consciousness. Somewhere in 30-40 minutes, the action of the poison ends, and the subjects return to normal, after which they happily and cheerfully go about their business.

Breeding at home

No matter how strange it may sound, modern exotic lovers are increasingly choosing poisonous amphibians as pets. Which is not at all surprising, because huge terrariums with colorful frogs sitting among lush vegetation are not only pleasing to the eye, but also resemble a piece of the jungle.


Modern exotic lovers are increasingly choosing poisonous amphibians as pets.

And, most importantly, it is absolutely safe to keep such an amphibian at home, since in an artificial environment it completely loses its poisonous qualities. This is primarily affected by a change in the diet and living conditions of the amphibian.

The most popular terrarium frogs today are poison dart frogs. The main advantages of these amphibians:

  • easy care;
  • the diversity and beauty of the frog;
  • small sizes;
  • dart frogs are completely suitable for room temperature;
  • even same-sex individuals get along well in the same terrarium;
  • have interesting behavior.

Terrarium for amphibian

Dart frogs are kept in horizontal type terrariums with moderate humidity and good ventilation. The dimensions of such a “house” must first of all be selected based on the size of the terrarium vegetation, which these frogs definitely need. For example, 2-3 pairs of individuals will feel great on a site measuring 60 by 60 cm with a wall height of about 50-70 cm.

As a soil, medium or coarse gravel can be used. It is very important that the stones are constantly slightly moistened, so once a day they must be sprayed with settled water.


Medium or coarse gravel can be used as soil for frogs.

The room temperature from + 22 to + 27 ° C is perfect for poison dart frogs, but at night it can be lowered to +18 ° C. Such conditions are quite sufficient for the normal life of both amphibians and terrarium plants. Since poison dart frogs are diurnal amphibians, special attention should be paid to lighting: frogs should be provided with good light for 12 hours.

In addition, ultraviolet radiation is vital for amphibians, so it is very important that the terrarium is equipped with such a device. In no case should you use special warming lamps designed for reptiles (especially desert lizards and turtles), because in strong light, the delicate skin of amphibians simply burns out.


Amphibians are vital to ultraviolet light, so it is very important that the terrarium is equipped with

As vegetation, low varieties with large leaves, such as tradescantia and various representatives of bromeliads, are well suited. A thick snag or a small part of a tree trunk is also required. The constant availability of fresh water is extremely important, which is recommended to be kept in a coconut shell.

Nutrition and reproduction

Experienced breeders traditionally feed dart frogs with fruit flies, a favorite delicacy of these frogs. However, a novice owner of amphibians with such “food” may experience some difficulties (flies have a not very pleasant feature to scatter throughout the apartment), so at the initial stage, frogs can be fed with caterpillar larvae or springtails.


The transformation of a tadpole into a frog is a long process that will take 2-3 months

Dart frogs reach their sexual maturity at the age of about a year. After fertilization, the females lay a very small number of eggs (only 3-5 pieces) in various shelters. After about 20-25 days, small tadpoles appear, which are immediately transferred to a small plastic bowl with clean water. Young animals are fed with the usual mixture for fry of aquarium fish. The transformation of a tadpole into a frog is a rather lengthy process, which will take 2-3 months.

Thus, even very dangerous and deadly frogs can turn into cute apartment pets, daily delighting their owner with funny behavior and beauty.

They mainly occupy the lower tiers of rainforests.

Natural populations and conservation measures

Due to the growing commercial demand for keeping these bright and attractive animals as pets, as well as due to the natural limitation of the distribution of certain morphological forms in their natural habitat, natural populations of frogs may decline and even disappear, thereby violating the ecological natural balance. Strict government measures to ban and regulate trapping - the removal of animals from countries - can help in the conservation of the species. Such measures were taken in Suriname and the endangered population of lat. Dendrobates has been restored. Restrictions on the export of animals have been introduced in many regions where these animals live, however, there is a private poaching of frogs for export and sale both through the zoo trading network of economically successful countries, and through individual small private business representative offices and firms. Some wild animals are sold under the guise of a domestic population or in the form of babies obtained from a wild form of an animal caught during the mating season. At present, due to the successful keeping and breeding of spotted poison dart frogs at home and in specialized farms, the threat of extinction of animals in natural conditions has been reduced.

Deforestation due to the development of industrial and agricultural production also affects the decline in populations of poison dart frogs.

Description of the species

Body shape is normal. The size of an adult is about 5-6 cm, but occasionally there are representatives of some variational forms, the size of which reaches 8 cm. There are no membranes between the toes. The tips of the fingers of the front paws are equipped with small suction cups. The colors are vibrant and varied. In general, females are larger than males.

Subspecies and variations

Behavioral features

Frogs are diurnal terrestrial near streams and small bodies of water or puddles, and very rarely climb above a fallen tree or small stump. Only the "Orange" or "Black and Yellow Giant" (lat. Dendrobates tinctorius Giant Orange ) are located on trunks in the crown of trees - at a height of one and a half to fifteen meters.

Frogs move in short dashes with frequent jerks and "bows"; jump rarely and over very short distances. Crawling vertically, they press against the surface with the belly and hips of the inner part of the hind legs - thereby holding on to weight.

Nutrition

reproduction

Like all dart frogs and leaf climbers, they breed on land and then carry the tadpoles on their own backs to the nearest body of water or to bromeliad leaves filled with rainwater. Eggs are laid in damp places directly on the ground or a leaf of a plant and taken care of until the tadpoles hatch.

Spawning is seasonal; as a rule, in the amount of 15 to 30 eggs. One of the parents (usually a male) is constantly near the masonry, periodically wetting it with water and stirring it with its hind legs. The females may eat the clutch. The hatched tadpoles are attached to the back of the parent and travel with him to a suitable body of water. In this position, they can remain for up to seven days, feeding on the remnants of the yolk. The development of tadpoles lasts 14-18 days, after which the young frogs switch to a terrestrial way of life.

Frogs are an increased focus for pet lovers in terrariums due to their diversity and attractiveness. Bright coloration, diurnal activity, interesting breeding behavior make you forget about their toxicity - you just need to prevent the frogs from escaping and communicate with them in rubber gloves. Young individuals and the new "home generation" are not so dangerous to human life.

For keeping frogs, a terrarium is used, which ensures the preservation of humidity and heat, as well as good ventilation. The volume of the terrarium is determined not by the requirements of the animals, but by the size of the plants that must be in it. It is desirable to provide for the possibility of adjusting the air flow and ventilation. The air temperature fluctuates between about 27°C during the day and 21°C at night.

Plants for the terrarium can be both ground and epiphytic: tradescantia, selaginella, various bromeliads with smooth non-thorny leaves. Epiphytes are placed in a position that is convenient and accessible to frogs. The accumulating water in the axils of the leaves of bromeliads serves the animals not only as a “bath”, but also as a “maternity room”.

When breeding frogs in terrarium conditions, a Petri dish is used, which is covered with coconut shell, and then the eggs in the cup are removed to a separate wet place (plastic vessel) for further artificial incubation. Before pecking, caviar in a cup is moistened with droplets of fresh, settled water from a pipette. When tadpoles hatch, they are carefully transplanted into a small pond or a bowl of water separately, where they are fed with various vegetable, live and granular foods. Tadpoles are prone to cannibalism. Water temperature 23-28°C.

The tadpoles hatched from the eggs and the juveniles that left the reservoirs are non-poisonous.

An excerpt characterizing the Spotted Dart Frog

“That's what, my dear, I was thinking about you,” said Prince Andrei, when they went into a large hall with clavichords. “There’s nothing for you to go to the commander-in-chief,” said Prince Andrei, “he will tell you a bunch of pleasantries, tell you to come to him for dinner (“it wouldn’t be so bad for service in that subordination,” Boris thought), but from this further nothing will come of it; we, adjutants and orderlies, will soon have a battalion. But this is what we will do: I have a good friend, an adjutant general and a wonderful person, Prince Dolgorukov; and although you may not know this, the fact is that now Kutuzov with his headquarters and we all mean absolutely nothing: everything is now concentrated at the sovereign; so we'll go to Dolgorukov, I should go to him, I already told him about you; so we'll see; whether he finds it possible to attach you with him, or somewhere there, closer to the sun.
Prince Andrew was always especially animated when he had to lead a young man and help him in social success. Under the pretext of this help to another, which he would never have proudly accepted for himself, he was close to the environment that gave success and that attracted him to itself. He very willingly took up Boris and went with him to Prince Dolgorukov.
It was already late in the evening when they went up to the Olmutsky Palace, occupied by the emperors and their entourage.
On that very day there was a council of war, in which all the members of the Hofkriegsrat and both emperors participated. At the council, contrary to the opinion of the old people - Kutuzov and Prince Schwarzernberg, it was decided to immediately advance and give a general battle to Bonaparte. The military council had just ended when Prince Andrei, accompanied by Boris, came to the palace in search of Prince Dolgorukov. Still all the faces of the main apartment were under the charm of today's military council, victorious for the party of the young. The voices of the procrastinators, advising to expect something else without attacking, were so unanimously muffled and their arguments refuted by undoubted evidence of the benefits of the offensive, that what was being discussed in the council, the future battle and, no doubt, victory, seemed no longer the future, but the past. All benefits were on our side. Huge forces, no doubt superior to those of Napoleon, were drawn into one place; the troops were animated by the presence of the emperors and rushed into action; the strategic point at which they had to act was known to the smallest detail to the Austrian general Weyrother, who led the troops (as if by a lucky chance, the Austrian troops were on maneuvers last year on exactly those fields on which they now had to fight the French); the present terrain was known to the smallest detail and shown on maps, and Bonaparte, apparently weakened, did nothing.
Dolgorukov, one of the most ardent supporters of the offensive, had just returned from the council, tired and exhausted, but animated and proud of the victory he had won. Prince Andrei introduced the officer he patronized, but Prince Dolgorukov, after shaking his hand politely and firmly, said nothing to Boris and, obviously unable to refrain from expressing those thoughts that most occupied him at that moment, turned in French to Prince Andrei.
- Well, my dear, what a battle we fought! God only grant that that which will be the result of it would be just as victorious. However, my dear,” he said in fragmentary and animated terms, “I must confess my guilt before the Austrians and especially before Weyrother. What precision, what detail, what knowledge of the terrain, what foresight of all possibilities, all conditions, all the smallest details! No, my dear, it is impossible to invent anything more advantageous than the conditions in which we find ourselves. The combination of Austrian distinctness with Russian courage - what else do you want?
“So the offensive is finally decided?” Bolkonsky said.
“And you know, my dear, it seems to me that Buonaparte has definitely lost his Latin. You know that today a letter has been received from him to the emperor. Dolgorukov smiled significantly.
– That's how! What does he write? Bolkonsky asked.
What can he write? Tradiridira, etc., all just to gain time. I tell you that he is in our hands; It's right! But the funniest thing of all,” he said, suddenly laughing good-naturedly, “is that they couldn’t figure out how to address the answer to him? If not the consul, it goes without saying not the emperor, then General Buonaparte, as it seemed to me.
“But there is a difference between not recognizing the emperor, and calling Buonaparte general,” said Bolkonsky.
“That's just the point,” Dolgorukov said quickly, laughing and interrupting. - You know Bilibin, he is a very smart person, he offered to address: "usurper and enemy of the human race."
Dolgorukov laughed merrily.
- No more? Bolkonsky noted.
- But still, Bilibin found a serious address title. And a witty and intelligent person.
- How?
“To the head of the French government, au chef du gouverienement francais,” Prince Dolgorukov said seriously and with pleasure. - Isn't that good?
“Good, but he won’t like it very much,” Bolkonsky remarked.
- Oh, and very much! My brother knows him: he dined with him more than once, with the present emperor, in Paris and told me that he had never seen a more refined and cunning diplomat: you know, a combination of French dexterity and Italian acting? Do you know his jokes with Count Markov? Only one Count Markov knew how to handle him. Do you know the history of the scarf? This is a charm!
And the garrulous Dolgorukov, turning now to Boris, now to Prince Andrei, told how Bonaparte, wanting to test Markov, our envoy, deliberately dropped his handkerchief in front of him and stopped, looking at him, probably expecting services from Markov and how, Markov immediately he dropped his handkerchief beside him and picked up his own without picking up Bonaparte's handkerchief.
- Charmant, [Charming,] - said Bolkonsky, - but here's what, prince, I came to you as a petitioner for this young man. Do you see what?…
But Prince Andrei did not have time to finish, when an adjutant entered the room, who called Prince Dolgorukov to the emperor.
- Oh, what a shame! - said Dolgorukov, hastily getting up and shaking hands with Prince Andrei and Boris. - You know, I am very glad to do everything that depends on me, both for you and for this nice young man. - He once again shook Boris's hand with an expression of good-natured, sincere and lively frivolity. “But you see…until another time!”
Boris was excited by the thought of the closeness to the highest power in which he felt himself at that moment. He was aware of himself here in contact with those springs that guided all those enormous movements of the masses, of which he in his regiment felt himself to be a small, obedient and insignificant part. They went out into the corridor after Prince Dolgorukov and met a short man in civilian clothes, with an intelligent face and a sharp line of protruding jaw, which, without spoiling him, gave him special liveliness and resourcefulness of expression. This short man nodded, as to his own, Dolgoruky, and began to gaze at Prince Andrei with an intently cold look, walking straight at him and apparently waiting for Prince Andrei to bow to him or give way. Prince Andrei did neither one nor the other; Anger was expressed in his face, and the young man, turning away, walked along the side of the corridor.
- Who is this? Boris asked.
- This is one of the most remarkable, but the most unpleasant people to me. This is the Minister of Foreign Affairs, Prince Adam Czartoryski.
“These are the people,” said Bolkonsky with a sigh that he could not suppress, while they were leaving the palace, “these are the people who decide the fate of peoples.
The next day, the troops set out on a campaign, and Boris did not have time to visit either Bolkonsky or Dolgorukov until the battle of Austerlitz, and remained for a while in the Izmailovsky regiment.

At dawn on the 16th, Denisov's squadron, in which Nikolai Rostov served, and who was in the detachment of Prince Bagration, moved from overnight to work, as they said, and, having passed about a verst behind other columns, was stopped on the main road. Rostov saw how the Cossacks, the 1st and 2nd squadrons of hussars, infantry battalions with artillery passed by him, and generals Bagration and Dolgorukov with adjutants passed by. All the fear that he, as before, experienced before the deed; all the internal struggle through which he overcame this fear; all his dreams of how he would distinguish himself like a hussar in this matter were in vain. Their squadron was left in reserve, and Nikolai Rostov spent that day bored and dreary. At 9 o'clock in the morning he heard firing in front of him, shouts of cheers, saw the wounded brought back (there were few of them) and, finally, saw how in the middle of hundreds of Cossacks they led a whole detachment of French cavalrymen. Obviously, the matter was over, and the matter was apparently small, but happy. Soldiers and officers passing back spoke of a brilliant victory, about the occupation of the city of Vishau and the capture of an entire French squadron. The day was clear, sunny, after a strong night frost, and the merry brilliance of the autumn day coincided with the news of the victory, which was conveyed not only by the stories of those who participated in it, but also by the joyful expression on the faces of soldiers, officers, generals and adjutants who were traveling back and forth past Rostov . The more painful was the heart of Nikolai, who in vain had suffered all the fear that preceded the battle, and spent this cheerful day in inaction.
- Rostov, come here, let's drink from grief! shouted Denisov, sitting down on the edge of the road in front of a flask and a snack.
The officers gathered in a circle, eating and talking, near Denisov's cellar.
- Here's another one! - said one of the officers, pointing to a French dragoon prisoner, who was led on foot by two Cossacks.
One of them led a tall and beautiful French horse taken from a prisoner.
- Sell the horse! shouted Denisov to the Cossack.
"Excuse me, your honor..."
The officers stood up and surrounded the Cossacks and the captured Frenchman. The French dragoon was a young fellow, an Alsatian who spoke French with a German accent. He was choking with excitement, his face was red, and, hearing French, he quickly spoke to the officers, addressing first to one, then to the other. He said they wouldn't take him; that it was not his fault that they took him, but le caporal, who sent him to seize blankets, that he told him that the Russians were already there. And to every word he added: mais qu "on ne fasse pas de mal a mon petit cheval [But don't hurt my horse,] and caressed his horse. It was evident that he did not understand well where he was. He then apologized, that they took him, then, assuming before him his superiors, showed his soldierly serviceability and care for the service.He brought with him to our rearguard in all the freshness the atmosphere of the French army, which was so alien to us.
The Cossacks gave the horse for two chervonets, and Rostov, now having received the money, the richest of the officers, bought it.
- Mais qu "on ne fasse pas de mal a mon petit cheval," the Alsatian said good-naturedly to Rostov when the horse was handed over to the hussar.
Rostov, smiling, reassured the dragoon and gave him money.
- Hello! Hello! - said the Cossack, touching the prisoner's hand so that he would go further.
- Sovereign! Sovereign! was suddenly heard among the hussars.
Everything ran, hurried, and Rostov saw several horsemen with white sultans on their hats driving up along the road. In one minute everyone was in place and waiting. Rostov did not remember and did not feel how he ran to his place and got on his horse. Instantly his regret for non-participation in the case passed, his everyday disposition of the spirit in the circle of looking at faces, all thought of himself instantly disappeared: he was completely absorbed in the feeling of happiness that comes from the closeness of the sovereign. He felt himself rewarded for the loss of this day by this closeness alone. He was happy, like a lover waiting for an expected date. Not daring to look back at the front and not looking back, he felt with an enthusiastic instinct its approach. And he felt this not only from the sound of the hooves of the horses of the approaching cavalcade, but he felt it because, as he approached, everything became brighter, more joyful, more significant and more festive around him. This sun for Rostov moved closer and closer, spreading rays of gentle and majestic light around itself, and now he already feels captured by these rays, he hears his voice - this gentle, calm, majestic and at the same time so simple voice. As it should have been according to Rostov's feelings, there was dead silence, and in this silence the sounds of the sovereign's voice were heard.

Or a dart frog, or a dyer frog, or a spotted woodworm (lat. Dendrobates tinctorius) - a species of poisonous frogs from the family of dart frogs, leading an exclusively diurnal lifestyle. Has many different color variations.


habitats


They inhabit the territories of Brazil, French Guiana, Guyana, Guyana and Suriname. They mainly occupy the lower tiers of rainforests.


Natural populations and conservation measures


Due to the growing commercial demand for keeping these bright and attractive animals as pets, as well as due to the natural limitation of the distribution of certain morphological forms in their natural habitat, natural populations of frogs may decline and even disappear, thereby violating the ecological natural balance. Strict government measures to ban and regulate trapping - the removal of animals from countries - can help in the conservation of the species. Such measures were taken in Suriname and the endangered population of lat. Dendrobates has been restored. Restrictions on the export of animals have been introduced in many regions where these animals live, however, there is a private poaching of frogs for export and sale both through the zoo trading network of economically successful countries, and through individual small private business representative offices and firms. Some wild animals are sold under the guise of a domestic population or in the form of babies obtained from a wild form of an animal caught during the mating season. At present, due to the successful keeping and breeding of spotted poison dart frogs at home and in specialized farms, the threat of extinction of animals in natural conditions has been reduced.

Deforestation due to the development of industrial and agricultural production also affects the decline in populations of poison dart frogs.

lat. Dendrobates tinctorius Yellow back (White legs) - spotted tree frog "Yellow-sided", or - "White-footed", up to 5.5 cm in size; lives at an altitude of 400-500 meters above sea level also in Suriname; a distinctive feature of this poison dart frog is the color - from the yellow color of the head, to lightening and turning into white along the entire back; the sides of the frog are black and the legs are black with pure white spots.

The tiny dart frog seems so defenseless at first glance. But this impression is very misleading. In fact, dart frogs are very dangerous. They are one of the most poisonous animals in the world. At least that's what the Guinness Book of Records says. Its poison is enough to kill 10 adults.


Dart frogs live exclusively in the jungles of Central America and South Africa.


These frogs grow in length no more than 15-25 mm. They have a very bright color (from pale yellow to blood red speckled), which indicates that they are very dangerous and it is better not to approach them. The paws are most often painted black. Because of this colorful coloring, they are also called "dye frogs".


These frogs are no bigger than a dime
Bright red color
Black color with red polka dots

Dart frogs are diurnal. They are constantly on the move and busy hunting.


They feed on small insects (beetles, ants, mites), some of which can be very poisonous.

It is known that poison frogs do not produce poison on their own. They get it along with food, for example, mites of the suborder Oribatida. But the most interesting thing is that without such a "dangerous feeding" the frogs lose their toxicity after a while.


Their venom is 20 times more toxic than that of other poisonous frogs. Being carriers of such a toxic poison, the frogs themselves remain alive and well. How they do it, scientists still do not know.


The poison is secreted by the skin glands. In its composition, it contains about a hundred different toxic substances, one of which is batrachotoxin. It causes cardiac arrhythmias leading to cardiac arrest.

From batrachotoxin, scientists were able to isolate a derivative substance - epibatidine, which is used as an anesthetic, like morphine. In addition, unlike the latter, epibatidine is not addictive.


Cautionary coloring warns of the danger of all living beings. But people have learned to use this poison for their own purposes. The Indians of Central America lubricate the tips of hunting and combat arrows (including blow darts) with it. Even a slight scratch with such a poisoned tip can result in death.

Hunters collect poison with fire. They hold the frog over the fire and, when it begins to secrete poison, they apply it to the tips of the arrows. Therefore, dart frogs received another name "arrow" or "poison dart frogs".


mating games

During the mating season, males call females with the help of croaking, which is more like a trill. When they find each other, the female begins to gently stroke the male with her paws on the back. Then she lays on the leaves of trees from 2 to 16 black eggs. The male leaves her alone for this time. And when the eggs are ready, he fertilizes them.

The eggs are in a gelatinous shell, which swells after fertilization and creates comfortable conditions for development for the embryos.

Unlike their parents, tadpoles are not poisonous, so they often become prey to various animals, in particular, land crabs. In some species of poison dart frogs, the male protects and cares for the masonry throughout the entire period of maturation.

Tadpoles hatch on the 8th day. After that, the female on her back carries the tadpoles one by one into flower buds on the tops of trees, in which rainwater accumulates. Such a pool is a kind of children's room, where children begin to grow. Unfertilized eggs serve as food for them.

Dart frogs have become popular with exotic animal lovers. They keep them in special terrariums and successfully breed them.

Very bright and amazing representatives of the world of frogs live in forests located in the expanses of Central and South America. Their body reaches sizes from 1.5 to 7 cm. However, due to its pronounced color, the poison dart frog catches the eye well. Individuals of this species are one of the smallest representatives of the amphibian order.

Amphibians of this species are called dart frogs. Regardless of the size of the individual, as well as what color it has, a characteristic feature for these representatives is that they are deadly poisonous amphibians. It is about such properties that their bright color speaks.

Blue dart frog

Individuals of this species are very beautiful representatives, having a size of less than 5 cm. The entire body of the frog is covered with black spots and dots, which in turn create a unique pattern on the skin. Suriname is the only place where the population of this species is still thriving.

The blue dart frog is a social animal that lives in small groups. Because of their toxicity, these amphibians are devoid of enemies, which in turn affects the confident behavior of these representatives of the amphibian world.

Quite often, you can observe the content of the blue dart frog at home, despite the fact that catching them is prohibited at the legislative level. It is only necessary to provide the pet with an appropriate humid and warm climate, as well as the necessary amount of stones and vegetation. As with all frogs, insects are the best food.

Spotted poison dart frog

These amphibians are the most poisonous of the entire family of poison dart frogs. Their poison may well paralyze a fairly large animal, despite the fact that the size of the frog does not exceed three centimeters. Frogs release the toxin through their skin. To date, there is no antidote.

The toxin that the poison dart frog secretes was used by the inhabitants of South America in ancient times to make their weapons. At the same time, they lubricated the tips of their arrows, which allowed them to resist the enemy and predatory animals.

Spotted poison dart frog is a diurnal inhabitant. It has a dark color, which is equipped with spots of various bright colors.

Gold dart frog

These representatives are also poisonous. Characteristic habitats are forests located in Colombia. They live in groups of 5-6 individuals. They have a rich yellow color, which warns that its owner has a high level of toxicity. If a person touches a golden frog, the transmission of all nerve impulses in his body will be disrupted, which may well lead to death.

Frog red

The first representatives of the red poison dart frogs were discovered in 2011, in the forests that are located on the territory of Costa Rica. They have a red color with an orange tint, while their hind limbs are blue. Dark spots are all over the body of the frog. The red poison dart frog has a very toxic venom that is dangerous to humans. A poisonous red dart frog is quite capable of poisoning a person, which can be fatal.

Home care

It is quite possible to keep such representatives of the frog world at home, since their toxins are produced in the process of life due to a certain diet.

In their natural environment for frogs, the food consists of ants, worms and termites, which in turn are very toxic. Since insects intended for feeding are not toxic when kept at home, poison dart frog gradually disappears. A necessary condition is to maintain a high temperature in the terrarium from 20 to 26 C and appropriate humidity.

Young frogs should be fed every day, while adult frogs will be enough to consume food every other day. The diet should be varied with the addition of mineral supplements for amphibians.

Gravel should be used as flooring for the terrarium. In order to retain water, you need to place a mixture of peat, tree moss or bark.

About which representatives can be kept at home, we wrote a separate article, they include, for example, other representatives of the amphibian world.

Not all representatives of poison dart frogs are toxic. For some, the bright color serves only to scare away.

The poisonous poison dart frog produces food not with the help of poison, but, like ordinary representatives of the frog world, with the help of its tongue. In this case, the size of the prey does not matter, the main condition is that it fits into the mouth of an amphibian.

Amphibians carry out their movement along the trunks and leaves of trees with the help of special pads on their paws, which secrete gluten that can hold the frog on absolutely any surface.

In captivity, poison dart frogs have a lifespan of seven years. However, if all the necessary conditions for the maintenance and normal habitat of amphibians are met, they can live up to ten years.
