Red-black frog. The most dangerous animals in the world: poisonous tree frogs
The ancient ancestors of frogs appeared on Earth approximately 290 million years ago, and nature decreed that the most beautiful representatives tailless amphibians are also the most dangerous. Tree frogs, frogs and toads mostly use toxic poisons for defense, and rarely attack first. Our short review presents the most poisonous frogs that have chosen rainforests, swamps and reservoirs of our amazing planet. And you can see in the article on our website the site
Phyllomedusa bicolor
Among tropical forests, located in the Amazon basin, lives such a beautiful, but rather dangerous phyllomedusa from the tree frog family.
The poison is not very toxic, but may cause distress gastrointestinal tract, hallucinations, severe allergies. Local Indians use its poison to treat all kinds of diseases and in initiation rites to enter a trance.
It is often called the monkey frog, and its habits make it a very curious amphibian. The species is listed as endangered and is therefore protected.
Striped leaf climber / Phyllobates vittatus
These colorful frogs, native to southwest Costa Rica, are colorful and appearance they warn that they are dangerous and it is better to avoid these wonderful creatures.
Easy to identify by characteristic yellow stripe, passing along the back. The stripes run along the head and along the sides of the abdomen, which is why the frog received its specific name.
It is not possible to notice it right away, since it prefers to hide in crevices and between stones. The poison, when it gets on human skin, causes severe pain and can even lead to paralysis.
Blue Darter / Dendrobates azureus
The cute creature, as seen in the photo, with a characteristic blue coloration, prefers savannas and tropical rainforests, and feeds mainly on small insects.
Even a small concentration of poison is enough to kill large natural enemies, and history has also recorded deaths among people. They grow up to 5 cm in length, and live among the foliage, gathering in groups of up to 50 individuals.
Despite mortal danger, wildlife lovers, get an American inhabitant as a pet.
Charming leaf climber / Phyllobates lugubris
Species name of the inhabitant Atlantic coast Central America is completely consistent with the appearance of the frog. Multi-colored stripes run along the black body, from yellow to bright golden.
Not as poisonous as other representatives of the leaf climber genus, but able to defend itself from natural enemies. Possessing poison, it does not hide much, so it can easily be found on forest paths and the banks of rivers and reservoirs.
They are distinguished by leaf climbers and huge bulging eyes on a relatively small head.
Red-backed poison frog / Ranitomeya reticulatus
This beauty with venom medium strength, lives among natural beauty Peru. It got its name from the characteristic red color of its back, while the rest of the body is spotted.
Despite the not very toxic poison produced by the glands of the frog, it is enough to cause health problems in humans, as well as kill the animal.
The frog receives poison by eating poisonous ants, and uses it in moments of danger. At other times, it is stored in glands on the frog's body.
In Panama and Costa Rica you can find one of the most poisonous toads, which has a bright color and does not grow more than 5 cm. Note that males are usually smaller and reach a length of only 3 cm.
When poison gets on the skin, the channels of nerve endings are blocked, and the person experiences a loss of coordination of movement, the person begins to have convulsions, and the sad result of all this can be complete paralysis.
Unfortunately, an antidote has not yet been invented, but it is necessary to carry out general detoxification in time, and then irreparable consequences for the health of the human body can be avoided.
Poison tree frog / Trachycephalus venulosus
Enough large frog, growing up to 9 cm in length, comes from Brazil, which is why it is also called the Brazilian tree frog.
It has an unusual coloration, consisting of spots of various sizes, forming a concentric pattern throughout the body. Distinctive feature There are also small red spots on the back and neck of the amphibian.
Prefer most lives in trees, and during breeding periods they move closer to bodies of water. Females lay eggs in ponds and lakes, which may dry out, but the offspring still survive early.
Little poison dart frog / Oophaga pumilio
A very tiny, red tropical frog lives high in the mountains among centuries-old trees tropical forests of Central and South America.
Bright, literally flashy coloring is a warning signal. It is better to avoid it so as not to get severe burns and health problems.
The poison is concentrated in the glands, and they get it by eating poisonous ants. It is noteworthy that he has one natural enemy- an ordinary one, on which poison dart frog has no effect.
Bernhard's Mantella / Mantella bernhardi
A resident of the island of Madagascar hides among fallen leaves, hunting for flies and other insects.
It has a characteristic black color, and males also have a horseshoe-shaped spot on their neck. Females do not have such a pattern, but they are larger in size than males.
A frog is not born poisonous, but over time the skin produces toxic poison, which leads to burns and allergies. This type of mantella leads the most active image life among other African species.
Common Toad / Bufo bufo
The distribution area of the gray toad is quite extensive, from the Siberian expanses of Russia to the western tip of Europe and North Africa.
The largest toad living in Europe is also poisonous. Poisonous toad is especially dangerous for livestock, as well as for humans. It is extremely undesirable for the venom of this amphibian to get into the eyes or onto the oral mucosa.
Another interesting point, in times of danger the toad takes threatening pose, rising high on his paws.
Spotted poison frog / Ranitomeya variabilis
Meet this forest beauty, whose body is painted with spots different colors and sizes, it is possible only in the vastness of Peru, and also in Ecuador.
But this beauty is deceptive, since the frog is one of the most poisonous creatures Latin America. Even a small amount of poison is enough to kill 5 people.
The venom is so toxic that lightly touching an amphibian can cause great harm to health. One consolation is that the frog is very calm and will never attack first.
Yeah / Rhinella marina
The poisonous tropical toad takes an honorable second place among all toads, but its toxicity makes it a leader among poisonous amphibians.
The largest specimen reached a size of 24 cm, although on average the toad grows from 15 to 17 cm. It comes from Central America, but to fight insects they were brought to Australia, from where Aga settled on the islands of Oceania.
The strongest poison affects the heart and affects nervous system. The most dangerous thing is that green toad can shoot poison over a distance.
Terrible leaf climber / Phyllobates terribilis
A small inhabitant of the rainforests on the southwestern tip of Colombia, the most poisonous frog in the world.
Adults grow no more than 2-4 cm, and the color is contrasting and quite bright. Yellow frogs so poisonous that even a slight touch to it is enough to cause death. Phyllobates terribilis is born non-poisonous, and then, by consuming insects, it produces poison.
The most interesting thing is that in captivity, the Colombian poison frog gradually loses its poisonousness, since the diet does not contain insects, which contribute to the production of the deadly poison.
Summarize
So we met, albeit beautiful, but very dangerous frogs, and, unfortunately, reports about people being poisoned by frogs quite often appear on news feeds. In nature, everything is thought out to the smallest detail, and the unusual color and appearance of amphibians acts as a kind of warning that this is a dangerous and poisonous creature.
This is one of the most large toads. The length of the agi toad can reach 25 cm ( the average size up to 18cm). The weight of these “cuties” is from one to two kilograms. Her body is heavy. On the head there are large swollen parotid glands that secrete a toxic fluid.
In huge bulging eyes horizontal pupils. She has well-developed ear drums located behind her eyes. The toad's vision is better than that of. The paws are thick and short in comparison with the size of the body. The hind limbs are webbed.
Warty skin has a dark brown color with black spots. The belly is lighter and the spots are smaller. The aga has well-developed lungs, because... her keratinized skin has poor contact with air. The skin is also covered with a special film that protects it from drying out. The toad doesn't jump very well, it's probably hard for her. But when it hunts, it sneaks up on the prey carefully, rearranging its paws. What kind of jumping is there, you will be left without food.
While hunting, she eats with her long tongue slugs, beetles, snails. Catches flying bees. It can eat a small lizard, and on the sea coasts they savor jellyfish and crabs. Lifestyle is nocturnal and solitary. When there is a lack of water, it buries itself in wet ground or sand so as not to lose moisture. During the day it hides, and at dusk comes out to fish. If she encounters an enemy, she takes a defensive pose and swells up.
Can shoot a secreted white secretion that contains deadly poison at the enemy. And although these amphibians defend themselves with poison, many animals do not care for it: lobsters, and water rats do not react to it. The aga is found in tropical forests, forest edges and coastal sand dunes. And the homeland of the agi toad is considered to be South and Central America.
IN mating season, males in standing waters they call females with a loud cry, similar to purring. The female lays eggs (from 4 to 35 thousand) in the form of long threads wound around leaves or stems aquatic plants. Having done her job, she immediately forgets about them. Soon, black, small, but very voracious tadpoles will emerge from the eggs.
After a few weeks, the tadpoles will grow into toads. The entire incubation period from the laying of eggs to the appearance of small toads lasts from 2 to 7 weeks. This range of dates is explained by environmental conditions - food, weather. And very few young individuals survive, approximately 1% of the eggs laid by one female.
By the way, its poison is not dangerous for humans until it gets on the mucous membranes. So whoever likes these amphibians can safely pick them up and enjoy communication. Just wash your hands afterwards. IN wildlife yeah, a toad lives 10 - 40 years.
The cane toad (aka Toad-aga) is a poisonous amphibian that is major representative family of toads. Description and photo cane toad they tell us that only Blomberg's toad is larger in size than the aga.
On top, the toad is gray or dark brown in color with large spots of a dark shade. The upper layer of the skin is warty and very faded. The toad's abdomen is yellowish, covered with dark spots.
The body length of the aga toad averages 16 cm, although some individuals can grow up to 25 cm. Body weight adult exceeds 1 kg.
Females are usually larger than males. The pupils have a horizontal arrangement, which is mainly due to nightlife of this type. The hind feet are webbed. At the edges of the skull there are glands that produce a toxic liquid.
Habitat of cane toads
The aga toad is distributed from northeastern Peru and the Amazon to the Texas Rio Grande River. It also lives in eastern Australia, where this toad was brought specially. The fact is that aga helps Australians fight insect pests, of which there are countless numbers. For the same purpose, the toad appeared in the Philippines, Florida, the Caribbean islands, and the islands of Japan.
Lifestyle of the reed frog
The aga toad lives from tropical forests to coastal dunes. Aga is one of the few amphibians that lives in salty waters at the junction of rivers with the sea or ocean, as well as on the shores of oceanic and sea islands. This toad has extremely well developed lungs. She owes this to her skin, which is very poor at gas exchange.
During the day, the aga hides in secluded places, being active only in the evening and at night. As a rule, these toads stay solitary. In defense, the toad greatly increases in size due to swelling. It moves along the surface, like many other toads, in quick short jumps.

For the tadpoles of this toad, snakes and turtles, as well as beetles and dragonflies, pose a danger. Adults often become prey for crows, rats, lobsters, crocodiles and other animals that have low susceptibility to the poisonous secretion of the aga.
Agha toad nutrition
This toad, unlike many others, is omnivorous. In addition to invertebrates and arthropods, the aga eats other amphibians, chicks, small rodents, and lizards. Sometimes it also feeds on carrion.
It even comes to the point that when long absence food aga can eat individuals of its own species. Tadpoles eat algae. Larger tadpoles can also feed on the eggs of individuals of their own species.

Reproduction
The monsoon period (June to October) is the most suitable time for breeding. At this time in large quantities Small intermittent bodies of water are formed. Males call females with characteristic sounds similar to purring. Toads reproduce using eggs. The female is capable of laying from 4,000 to 35,000 eggs in one mating season. Adults do not care for their offspring.
The incubation period of eggs ranges from 2 to 7 days. The tadpoles and eggs of the aga are poisonous to humans and many animal species.

Yad agi
To defend itself from attack, the toad is capable of shooting out a poisonous secretion. Secret white, secreted from the glands, is a very dangerous, potent poison. This poison has a destructive effect on the nervous and cardiovascular systems. This leads to arrhythmia, convulsions, vomiting, temporary paralysis and increased blood pressure. It is not for nothing that the indigenous population of South America used the poison of this toad to enhance the deadly effect of arrows, applying it to the tips.
The most poisonous frogs, ironically, have the most amazing and beautiful appearance, however, it is extremely undesirable to touch them. Just one touch to the skin of these creatures can cost you your life. Find out more about the most poisonous, but very colorful and beautiful frogs.
1) Bicolor phyllomedusa
Phyllomedusa bicolor
![](https://i0.wp.com/infoniac.ru/upload/medialibrary/2ba/2ba7f23909102277f6e488afdc50c187.jpg)
This large frog, often called the monkey frog, is very curious. Although its venom is not as dangerous as that of some other representatives of the frog world, most of us are unlikely to want to try its effects: the venom can cause unpleasant hallucinations or stomach problems. We say "most of us" because some tribes on the banks of the Amazon do deliberately use their poison to induce hallucinations.
2) Spotted poison dart frog
Dendrobates tinctorius
![](https://i2.wp.com/infoniac.ru/upload/medialibrary/85a/85ad1d18779da5ecb5121c57262d5348.jpg)
This amazing beauty the frog may have different colors skin, it is interesting not only because its skin is poisonous, which should not be forgotten, but also because its poison has a special effect on parrots. Indigenous peoples of the Amazon use frog poison to change the color of the feathers of parrots.
3) Red-backed poison frog
Ranitomeya reticulatus
![](https://i1.wp.com/infoniac.ru/upload/medialibrary/47a/47ae0e35e735bbffac76dc85b78bd286.jpg)
Native to Peru, this frog has a mild venom that can cause health problems in humans and can kill some animals. Like other poisonous frogs, these beautiful little creatures require special food to produce their poison. In this case, the “raw material” of poison for them is a poisonous ant. The frog stores poison in the skin glands and releases it as needed. Most often this happens in case of danger, when some predator is about to eat the frog.
4) Little poison dart frog
Dendrobates pumilio
![](https://i1.wp.com/infoniac.ru/upload/medialibrary/d2c/d2cfb1d6e1ce4faf6a5232dcb765ef0b.jpg)
Very small in size, but quite bright and beautiful, this strawberry frog is found in impenetrable forests Central America. Her bright color warns: “Stay away, otherwise you will get burned.” You should take the threat seriously, as the frog can really sting painfully, and the sensation is similar to a burn.
5) Blue dart frog
Dendrobates azureus
![](https://i2.wp.com/infoniac.ru/upload/medialibrary/bd8/bd88b50e66149e20452a50aa02264a4e.jpg)
This frog is really very cute, as can be seen from the photo. However, its beautiful and bright color does not bode well: its poison is enough to kill even the largest natural predator; there are cases where even people died from this poison. However, some brave people keep these creatures at home as pets. How is this possible, you ask? Fortunately, in captivity frogs lose their poisonous properties, because they do not receive special food to produce poison, and they don’t need it, since no one will offend them in the aquarium. The frog retains its wonderful appearance, but loses its poison. This applies to all frogs on our list.
6) Charming leaf climber
Phyllobates lugubris
![](https://i1.wp.com/infoniac.ru/upload/medialibrary/350/35029f39878ba7f8beea19c485803e23.jpg)
The charming leaf climber is the least poisonous of its genus, although it still makes its victims bitterly regret that they tried to attack it. He is called "charming frog" only because of his appearance. If you want to find representatives of this species in nature, you should go to Central America. It is unlikely that you will have to look for it for a long time, since such poisonous creatures are usually not going to hide from someone.
7) Striped leaf climber
Phyllobates vittatus
![](https://i2.wp.com/infoniac.ru/upload/medialibrary/ffb/ffbc65e3adb8ea98289201ce3928533a.jpg)
As with the frogs mentioned above, these small amphibians with their bright colors warn enemies that they are not as defenseless as they seem, so you should stay away from them. The venom of these creatures causes severe pain and can even lead to paralysis.
8) Spotted poison frog
Ranitomeya variabilis
![](https://i0.wp.com/infoniac.ru/upload/medialibrary/9d5/9d5758be24c124c2181f52e629bb21f4.jpg)
These beautiful creatures live in the tropical forests of Ecuador and Peru and are among the most poisonous representatives sort of Ranitomeya. The poison of one frog can be enough to kill 5 people! Although the frog looks very cute, it should not be touched under any circumstances. Even if you are lucky enough to visit the forests of Ecuador or Peru, you should not be afraid to encounter a frog. She will never attack first.
9) Three-striped leaf climber
Epipedobates tricolor
![](https://i1.wp.com/infoniac.ru/upload/medialibrary/864/864242f89675b027ab89584c6a8a23a5.jpg)
These frogs are very small, but are one of the most deadly amphibians. They can kill not only large animals, but also humans, so no one would think of playing with them. Frogs are endangered, so they can rarely be found even in their homeland - in the forests of Ecuador. To save these frogs and increase their numbers, researchers are trying to breed them in captivity. Preserving them is also important from a medical point of view: the poison of these frogs is 200 times stronger than morphine and is an excellent pain reliever.
10) Terrible leaf climber
Phyllobates terribilis
![](https://i1.wp.com/infoniac.ru/upload/medialibrary/710/7105646d492a2b7ab194b479c1fa4e48.jpg)
This extremely poisonous frog lives in Colombia. Despite their eye-catching appearance, these creatures are not the type to play with: their bright colors warn of danger. In fact, these frogs are so poisonous that a person can die just by touching them, hence the name. Terrible leaf crawlers They do not use poison to kill their prey, but only to protect themselves from predators. Therefore, if you see frogs in the forest, but do not try to touch them, they will not cause you any harm.
Tree frogs, also known as tree frogs, are the most colorful members of the amphibian order - their colors range from yellow and green to red and blue mixed with black. Such a bright range is not just a quirk of nature, it is a signal for predators, warning of danger. Producing a poisonous toxin that can paralyze, stun and kill even a large animal, tree frogs have firmly established themselves in the impenetrable tropical forests of Central and South America, where high humidity and the enormous biodiversity of insects allows them to survive for more than 200 million years. Having appeared on Earth at the same time as dinosaurs, frogs demonstrate extraordinary adaptation to the environment - painted in all the colors of the rainbow, they are practically invisible among lush vegetation and inedible for most representatives of the fauna.
- The Amerindians have long learned to benefit from the poison of poison dart frogs, using it as a deadly substance to lubricate the tips of their hunting darts. Having pierced the frog with a stick, the Indians first held it over the fire, and then collected the droplets of poison that appeared on the skin of the animal into a container, after which they dipped the arrows in a viscous liquid. This is where another name for poisonous tree frogs came from - dart frogs.
Unusual facts from the life of poison dart frogs
- Among the brightly colored 175 species of tree frogs, only three pose a threat to humans; the rest mimic toxicity in their appearance, although they are not poisonous.
- The size of dangerous tree frogs reaches 2-5 cm, and females more men's.
- Tree frogs climb trees thanks to the rounded ends on their legs that resemble suction cups. Making circular movements with their limbs, they move quite easily along the vertical plane of a tree trunk.
- Poison dart frogs prefer to live alone, carefully protecting the boundaries of their territory, and only come together for a while mating season after reaching 2 years of age.
- Tree frogs acquire their bright colors with age; baby frogs always have a nondescript brown color.
- The frog's body does not produce poison - it adsorbs toxins small insects. Toxic secretions appear on the skin of an amphibian at the moment of danger and are caused by a specific “diet”, which includes ants, flies, and beetles. Tree frogs raised in captivity, away from their natural place habitats and deprived of their usual food, are absolutely harmless.
- Dart frogs are both diurnal and nocturnal, climb the ground and trees, and use a long sticky tongue when hunting.
- The life cycle of tree frogs is 5-7 years, in captivity – 10-15 years.
Yellow poison dart frog
Living in the Andean foothills - in the coastal zones of southwestern Colombia, the most poisonous frog in the world is the terrible leaf climber. ( Phyllobates terribilis ) , prefers growing on rocks 300-600 m above sea level. Deciduous litter under the crowns of trees near the reservoir - favorite place for the most dangerous vertebrate in the world - the yellow-gold tree frog, whose poison can kill 10 people at a time.
The distribution zone of the 1.5 cm strawberry tree frog (Andinobates geminisae), from the family of poisonous leaf climbers, first found in 2011, is the jungle of Costa Rica, Nicaragua and Panama. The red-orange palette of the unusual amphibian's body is adjacent to bright blue on the hind legs and black markings on the head. After the dreaded golden leaf frog, the red tree frog is the second most toxic species in the world.
Okopipi blue poison frog
In 1968, the sky-blue tree frog Dendrobatus azureus was first discovered by scientists in the humid tropics. A bright shade of cobalt or azure sapphire with black and white flecks is a classic Okopipi colorway. The poisonous tree frog received its name from local aborigines a long time ago - unlike scientists, the Amerindians have known it for many centuries. The distribution area of the unusual vertebrate is the relict tropical forests surrounding the Sipaliwini savanna, which extends across southern regions Suriname and Brazil. According to scientists, the blue dart frog was, as it were, “canned” in this area during the last Ice Age, when part of the jungle turned into a grassy plain. The surprising thing is that Okopipi does not know how to swim like all amphibians, and it gets the necessary moisture in the humid thickets of the tropical forest.
The distribution area of the red-eyed tree frog - Agalychnis callidryas, is quite extensive: from Northern Colombia, across the entire central part America, to the southern tip of Mexico. Lives this type amphibians mainly in the lowlands of Costa Rica and Panama. The coloring of the “big-eyed” dart frog is the most intense in the family of tailless vertebrates - neon spots of blue and blue are scattered against a bright green background. orange color. But the eyes of this amphibian are especially remarkable - scarlet, with a vertical narrow pupil, they help the harmless little frog scare away predators.
In the east of the continent, there is another species of red-eyed frog - Litoria chloris - the owner of a rich light green color with yellow splashes. Both types of tree frogs are not poisonous despite their expressive “outfit” and piercing gaze.
Interesting to know! Many animals have striking colors - warning colors developed during evolution to protect against predators and indicating the toxicity of its owner. As a rule, this is a combination of contrasting colors: black and yellow, red and blue or others, a striped or drop-shaped pattern - even those predators that are naturally color-blind can distinguish such colors. In addition to the catchy color scheme, miniature animals have large eyes that are incommensurate with the size of the body, which creates the illusion in the dark large organism. This feature, intended for survival, is called aposematism.
Medical uses of tree frog venom
Scientists' research into the pharmacological use of frog toxins began back in 1974, when the US National Institutes of Health first conducted experiments with dendrobatid and Epidatidine, the main components of tree frog venom. It turned out that in its pain-relieving properties one substance is 200 times superior to morphine, and the other is 120 times superior to nicotine. In the mid-90s, scientists at Abbott Labs. managed to create a synthetic version of epidatidine - ABT-594, which significantly reduces pain, but does not put people to sleep like opiates. The American Natural History Museum team also analyzed 300 alkaloids found in tree frog venom and determined that some were effective in treating neuralgia and muscle dysfunction.
- The largest frog in the world is the goliath (Conraua goliath) from West Africa, the length of her body (excluding legs) is about 32-38 cm, weight - almost 3.5 kg. The giant amphibian lives in Cameroon and Guinea, on sandy shores African rivers Sanaga and Benito.
- The smallest frog in the world is the tree toad from Cuba, it grows 1.3 cm in length.
- In total, there are about 6 thousand species of frogs in the world, but every year scientists find more and more new species.
- A toad is the same as a frog, only its skin is dry, unlike frogs, and covered with warts, and its hind legs are shorter.
- The frog sees perfectly at night and is sensitive to even the slightest movement; in addition, the location and shape of the eyes allows it to perfectly view the area not only in front and to the sides of itself, but also partially behind.
- Thanks to their long hind legs, frogs can jump a distance of 20 times their body length. The Costa Rican tree frog has membranes between the toes of its hind and front paws - this unique aerodynamic device helps it float in the air when it jumps from one branch to another.
- Like all amphibians, frogs are cold-blooded - their body temperature changes in direct proportion to the parameters environment. When the air temperature drops to a critical level, they burrow underground and remain in suspended animation until spring. Even if 65% of a tree frog's body is frozen, it will survive by increasing the concentration of glucose in its vital fluid. important organs. Another example of vitality is demonstrated by the Australian desert frog - it can survive without water for about 7 years.
New species of frogs and toads found in the world
Recently, in the highlands of western Panama, a the new kind golden tree frog. Scientists were able to spot the amphibian in dense foliage due to an unusual loud croaking sound, unlike any previously studied. When zoologists caught the animal, a yellow pigment began to appear on its paws. There was a fear that the discharge was poisonous, but after a series of tests, it turned out that the bright yellow mucus did not contain any toxins. A strange feature of the frog helped the scientific team come up with scientific name- Diasporus citrinobapheus, which conveys the essence of her behavior in Latin. Another new look poisonous frogs— Andinobates geminisae, scientists found in Panama (Doroso, Colon province), in the upper reaches of the Rio Caño River. According to experts, the neon orange frog is on the verge of extinction, since its habitat is extremely small.
On the island of Sulawesi near the Philippine archipelago, scientific group discovered the existence large quantity clawed frogs - 13 species, and 9 of them were hitherto unknown to science. Differences are observed in the body size of amphibians, the size and number of spurs on the hind legs. Due to the fact that this species is the only one on the island, nothing prevents it from breeding and reproducing, unlike its relatives in the Philippines, where clawed tree frogs compete with another species - amphibians of the Platymantis family. Fast growth the number of island anurans clearly demonstrates the correctness of Charles Darwin’s concept of adaptive distribution, described using the example of finches from the Galapagos archipelago.
Biodiversity of frogs on Earth
- Vietnam. About 150 species of amphibians are common here; in 2003, 8 new species of frogs were found in the country.
- Venezuela. An exotic state is sometimes called " lost world“—many table mountains, difficult to reach for researchers, are distinguished by endemic flora and fauna. In 1995, a group of scientists undertook a helicopter expedition to the Sierra Yavi, Guanay and Yutaye mountains, where 3 unknown to science species of frogs.
- Tanzania. A new species of tree frog, Leptopelis barbouri, has been discovered in the Ujungwa Mountains.
- Papua New Guinea. Over the past decade, 50 unstudied species of tailless amphibians have been discovered here.
- Northeastern regions of the USA. Habitat of the rare spider-like toad.
- Madagascar. The island is home to 200 species of frogs, 99% of which are endemic - unique species not found anywhere else. The scientists' latest find, the narrow-mouthed toad, was discovered through a study of the soil and foliage of the jungle, during which they were able to identify the amphibian's excrement.
- Colombia. The most outstanding discovery of scientists in this region is the species of tree frog Colostethus atopoglossus, which lives only on the eastern slopes of the Andes, in El Boquerón.
Argentina, Bolivia, Guyana, Tanzania and many other countries with a tropical climate and difficult landscapes are regions where scientists are constantly finding new subspecies of animals, including tailless amphibians - frogs. Holders miniature sizes, arboreal representatives of the amphibian order are not only the smallest, but also the most dangerous animals in the world - modern zoologists are increasingly convinced of this.
