The Panamanian Golden Frog is an extremely poisonous amphibian, even just touching it causes a severe allergic reaction.
All species of the golden frog family contain dangerous substances on their skin, but the venom of the Panamanian golden frog is the most dangerous and toxic.
On the surface of her skin is so much strong poison that it is enough to kill several healthy adult men. The natives used this poison to coat arrowheads by rubbing them with the skin of a freshly caught frog.
The toxins of the golden frog are so unique that scientists have classified it as a separate type of amphibian.
Where does such a small amphibian get so much poison? Scientists believe that the frog's body processes the food it eats, releasing and concentrating toxins from it, which, in the end, are excreted by glands on the surface of the skin. The poison of this crumb is called batrachotoxin ("batracho" - a frog in Greek) and acts mainly on cardiovascular system and nervous system human (and any other animal). There is only one animal in nature that is not afraid of these deadly frogs and even feeds on them - this is the Leimadophis Epinephelus snake.
Baby frogs are more poisonous than adults, so they can better protect themselves until they grow up. And the older they get, the more yellow the color and the more black dots.
Males and females of the golden frog are almost the same color. It differs only in the degree of brightness and can be either light yellow or bright golden. They also have a few black spots on their backs and legs, but sometimes none at all. Females are usually larger than males in body length (by about twenty-five percent) and in weight.
Panamanian golden frogs choose rain (moist) forests and dry forests near the Cordillera Mountains in Panama as their habitat. Most the best place for them, these are reservoirs, and with fast current. During the day, they are mainly busy hunting small insects. It seems strange that such a small creature should live freely during the day, given that this species of frog is extremely poisonous, but the bright coloration warns predators that the frog is toxic and a serious danger. The closest relatives of this species are found in South America and in Madagascar, and are also brightly colored, warning of how toxic the species is.
Male Panamanian golden frogs emit a whistle and are also capable of making two long, loud calls that can be heard throughout the forest. Golden frogs communicate using the so-called semaphore system. They use their forelimbs to make contact with potential partners and adversaries. As you know, most species of frogs communicate with the help of croaking. However, there is a theory that this type of frog has developed the ability to communicate precisely through the limbs, due to the high level of noise of water bodies in their habitat. Like many hearing impaired people, golden frogs communicate through sign language, signaling to each other. They "wag" their paws, or raise one paw up, to defend their territory, attract a male or female, and even to communicate when they meet. Research into this rare communication method for frogs is still ongoing.
Now officially the Golden Frog is considered to be on the verge of extinction, probably they are completely gone in nature. In 2006, scientists were forced to remove the remaining toads from wildlife to save the species.
The reason for the disappearance of the golden frog is not exactly known. But, most likely, to the catastrophic decline in the population of the frog, like many other species of atelope, chytridiomycete fungi began.
The golden frog is one of national symbols Panama, her image can be seen on lottery tickets, she is mentioned in local mythology.
In Panamanian schools, students are told that, according to folklore (even before the discovery of America by Columbus), when this frog died, it turned into gold. This little frog is believed to bring good luck. And for many years, figurines in the shape of a golden frog have been placed in hotels and restaurants, as well as making souvenirs from gold and giving people as a talisman. Anything to get lucky. There was a belief that when the golden toad dies, it turns into gold. It was also believed that she brought good luck even to those who simply saw her.

The Panamanian golden frog, or Atelopus zeteki, belongs to the family of Real toads (lat. Bufonidae). According to Indian beliefs, after death, it turns into pure gold. Even a fleeting touch to her skin causes severe burns and an allergic reaction.
It received its scientific name in honor of the American entomologist of Czech origin James Zetek, who became famous for his research in the field of the influence of chemicals on termites and ways to protect furniture from their invasion. Her image is placed on the tickets of the national Panamanian lottery, therefore, many are perceived as a symbol of the country.
This amphibian is one of the most poisonous creatures on our planet. To protect against predators, the surface of its body contains the neurotoxin tetrodotoxin, which has a neuroparalytic effect. His concentration is enough to send several people to the next world.
Local Indians traditionally oil arrowheads with it before hunting and keep these dangerous but cute creatures as pets.
The species was first described in 1933 by the American zoologist Emmett Ride Dunn.
Spreading
Atelope Cetek belongs to the number of endemic species Central America. Currently found only in the central regions of Panama. The last populations of the golden frog survived in the provinces of Western Panama and Cocle. They live in the vicinity of the small town of El Valle de Anton and in national park Altos de Campana at altitudes of 330-1300 m above sea level.
The species Atelopus zeteki is at the stage of extinction. In the Houston Zoo (USA), work is underway to breed it in captivity with further settlement in its natural habitat. Amphibians inhabit tropical rainforests and can be both terrestrial and arboreal.
Frogs are often infected with the deadly fungus Batrachochytrium dendrobatidis. They are not able to develop immunity against it, which led to a catastrophic decrease in their numbers. So far, no effective cure for this scourge has been developed.
Communication
Panamanian golden frogs communicate with each other through throat sounds and intricate foot movements. The arsenal of communication signals is quite extensive and can transmit a relatively large amount of information. Gestures are used mainly to establish a hierarchical structure, social relationships, show hostility or friendliness.
Living amphibians perceive the limb positions of inanimate mannequins as a call to action; after an unpleasant combination, they may come to real rage and attack artificial tribesmen. Sound signals are more often used to attract individuals of the opposite sex and in case of danger.
Food
The larvae feed on microorganisms, while the adults eat insects, spiders, and centipedes. Hunting is carried out during daylight hours. The peak of its activity falls on the morning and evening hours.
The frog searches for prey mainly on the surface of the soil, walking along the fallen leaves.
If necessary, deftly jumps on the branches and extracts trophies there. The predator hunts from an ambush, grabbing the victim with a lightning movement of the tongue.
reproduction
The golden frog reaches sexual maturity at one year of age. The mating season takes place in the summer during the rainy season, when floods form, therefore, hollows of trees filled with water or shallow depressions on hills are used for spawning.
Males croak tirelessly to lure females. Spawning and fertilization occur simultaneously. In one clutch there are up to 100 eggs, of which no more than 70-90% are fertilized.
For several days, the male alone guards the masonry, waiting for the birth of offspring while the incubation lasts.
If by this time the water in the hollow or in the puddle has dried up, then the caring father transfers his children to the nearest other body of water.
The development of tadpoles lasts up to 4 weeks. Lack of food leads to cannibalism among the larvae. The surviving lucky ones go through a complete metamorphosis and turn into young frogs about 10 mm long and weighing 1 g. They have a green color that gradually disappears as they grow older.
Description
The body length of males reaches 35-47 cm, and females 45-63 mm. Weight ranges from 4 to 15 g. The slender body looks very fragile.
Smooth skin dyed yellow or orange with many dark spots various shapes. The head is slightly narrowed towards a short muzzle.
Large eyes with elliptical pupils are located on the sides of the head far forward. The ears are not visible, the eardrum is covered with skin. Poison glands are located behind the eyes.
The life span of the Panamanian golden frog is about 12 years.
So, today we have Saturday, July 1, 2017 and we traditionally offer you answers to the quiz in the "Question - Answer" format. The questions we meet are both the most simple and quite complex. The quiz is very interesting and quite popular, but we just help you test your knowledge and make sure that you have chosen the correct answer out of the four proposed. And we have another question in the quiz - How do Panamanian golden frogs communicate?
- A. writing
- b. sign language
- C. infrasound
- d. ultrasound
The correct answer is B - sign language
Driven almost to extinction due to habitat loss, the Panamanian golden frog lives exclusively in tropical forests Panama, mostly near fast-flowing rivers and waterfalls. Because of the big noise in their natural environment they have developed a capability that is very rare in the animal kingdom: they use a semaphore.
A rudimentary form of sign language, which is the semaphore, is used by frogs to convey basic messages, such as a desire to mate or a warning of the approach of natural enemies.
The males of these frogs also make whistling sounds, despite the fact that these sounds are practically useless due to the fact that this species of frog does not have eardrums.
