They are also unique as they are active during the day, as opposed to being nocturnal like most frog species.
There are more than 100 species of poison dart frogs, most of which live in the Amazon. Posison dart frogs are brightly coloured  – they can be yellow, copper, gold, red, blue, green, black or a combination of those colours – and notoriously poisonous where its striking hue helps warn off predators. They are also unique as they are active during the day, as opposed to being nocturnal like most frog species. The amphibian is terrestrial with a few arboreals, and loss of its habitats increasing food competition and risks of being preyed upon, causing these frogs to become move closer to extinction. Scientists also found chytridiomycosis, a bacterial disease found in amphibians, to have killed thousands of animals each year, which resulted in the extinction of some species.
