Poison jewels: the dart frogs
These South American frogs are brightly coloured and highly poisonous. The colour alone deters many predators, but when threatened, these frogs also release deadly poisons through their skin.
All dart frogs in the Dendrobatidae family (about 170 species) are toxic to different degrees. These poisons taste fowl and are inedible by predators. However, some poisons are far worse, causing rapid paralysis and death of an attacker if they enter their bloodstream through the mouth.
Green and black poison dart frog (Dendrobates auratus) – a least concern species from Panama, Costa Rica, Nicaragua, and Colombia.
Safe in captivity
Our frogs at The Living Rainforest are entirely harmless, they are only toxic when they eat certain foods in the wild.
Medicine from frogs
Researchers have recently developed a painkiller known as ‘ABT-594′ using the dart frogs’ poison. This is 200 times as powerful as morphine, but without any side effects or addiction.
The toxins from Dendrobates auratus are being studied for their potential use in treating heart attacks.
