The Bi-coloured Poison Dart Frog is a close relative of the
Golden Poison Frog and, like all Phyllobates frog
species, is highly toxic (the second most toxic frog). The toxicity derives from their
diet (plant toxins eaten by beetles which are then eaten by
the frogs) and is lost in captive bred frogs. Their name comes from their
use to poison tips of blow darts by native tribes.
Its usual body colouring is golden yellow with dark hind
legs and forearms, ranging from green to dark blue to black
and sometimes including the rump. Some morphs have uniform
golden body colour.
It lives in the undergrowth of forests in a small area of
western Colombia. The female frogs lay eggs on land and males
carry tadpoles on their backs to ponds.
