![]() They are popular pets, driving an illegal trade.ĭue to their bright colours and small size, they have become popular exotic pets internationally. Males will fight over the best spots to do their mating calls from, while females fight over the best nests. Both males and females fight over territory. This helps the tadpoles become poisonous. Mother poison dart frogs supply their tadpoles with poison.Ī study found that mother frogs will feed their tadpoles unfertilised eggs which are high in toxins. For example, the strawberry poison dart frog carries individual tadpoles up to almost the top of the canopy where she places it in the water that gathers in the leaves of bromeliads. She’ll take each tadpole to its own little pool, then bring each of them food. Some mothers carry individual tadpoles to individual pools. Mothers may then continue to care for the tadpoles by bringing them unfertilised eggs to eat.ġ5. Poison dart frog mothers will often hang around until the eggs have hatched and then carry the tadpoles to a near water source. Many species carry the hatched tadpoles on their backs. They will lay their eggs in moist places, such as on plants higher up or in the leaf litter of the forest floor. Poison dart frogs often lay their eggs on plants or roots. This is part of the reason why they have such bright colours and high toxicity as it allows them to repel predators that are active during daylight. This is unusual as most amphibians are usually active at night. This means that they are active during the day. Recent research has found a compound in the toxins that is a painkiller stronger than morphine, but with none of the side effects. Research has shown that toxins from these frogs have various medical uses. The Fire-bellied snake (Leimadophis epinephelus), has evolved to have immunity to the highly toxic golden poison dart frog (Phyllobates terribilis), making them the frogs’ only predator. One snake has evolved resistance to the toxins. One frog has an average of one milligram of poison, which is enough to kill up to 20 people, or two African bull elephants.ġ0. The toxin from this poison dart frog can stop the human heart almost instantaneously. The golden poison dart frog is the most toxic. As well, pet poison dart frogs that are kept as pets lose their toxicity as they no longer have access to their normal diet. This seems likely as those with the highest toxicity, consume the most ants. While scientists aren’t sure, it seems that the toxins the frogs produce come from a diet high in toxin-containing animals, such as ants or centipedes. Their toxins likely come from their diets. The most toxic species have very bright colours, while those that aren’t toxic are dull.Ĩ. The degree of toxicity generally coincides with how bright they are. Predators see their bright colours and know they are not safe to eat. This is the scientific term given to animals that signify their toxicity with bright colours. Overtime, animals learn not to consume them. When a predator consumes them, they either die or are extremely ill. They never use these toxins to attack or for hunting, they are only for self-defence. Their toxins are for self-defence, not hunting. When stressed, a frog may secrete large amounts of toxin all at once.ĥ. They are stored in glands under the skin, with the toxin being secreted through pores. Their toxins are secreted from their skin. This means that they do not inject their toxins into others, like snakes, they instead have to be consumed or licked. There are a huge variety of poison dart frogs, and not all of them are poisonous. ![]() There are over 170 species of poison dart frog. Indigenous people use just 4 species of poison dart frog, which have some of the highest toxicity of all dart frogs.Ģ. Their toxins were placed in the tips of blow darts, giving them their name. Indigenous peoples used their toxins to make darts. ![]() They can live up to 15 years in the wild, and longer in captivity. As amphibians, they need to be near a source of water. The majority live on the forest floor, however some like to live up in the canopy. They are found in tropical regions of Central and South America, where they inhabit humid topical forests like the Amazon. ![]() Many are colourful to show of how dangerously toxic they are, while others are plain and completely non-toxic. There are over 170 species of poison dart frogs, but not all are poisonous. Some are bright colours (yellow, green, gold etc) while others are more dull (green, brown, black)įire-bellied snake (Leimadophis epinephelus) Their name comes from the fact that indigenous Amazonian groups use the poison from several species of the frog to make poison darts. This is a group of frogs from the family Dendrobatidae, that are well known their bright colours and highly toxic nature. ![]()
