The Dendrobatidae are a family of anura amphibians known as poison dart frogs.
These frogs receive their colloquial name from the numerous types of venomous alkaloids found on the skin of many species. Dart frogs need just 0,00001 grammes of poison to kill an adult human. The toxin found in just one single specimen can kill one thousand five hundred people, and although not all species of this type of animal have the same venom, their effects are similar. Predators that try to eat them suffer great nausea and vomiting, if not death.
These frogs are popularly characterised by their brilliant two-tone colour and small size. The range of colours goes from luminous orange and blue-black to yellow and red. However, members of the most numerous species, Colostethus, are generally chestnut in colour. They grow to between 1 and 6cm in length, depending on age and species of frog.
