These amphibians usually sequester toxins from animals and plants on which they feed, commonly from poisonous insects or poisonous plants.

Poison dart frogs suffer from chytridiomycosis, which is a deadly disease that is caused by the fungus Batrachochytrium dendrobatidis (Bd). This infection has been found in frogs from Colostethus and Dendrobates. [61] [62]
