Oophaga granulifera
The granular poison frog (Oophaga granulifera) is native to Costa Rica where I took this picture during my 2017 spring break. I believe that this is a granular poison frog from from the Dendrobatidae family because its natural habitat is the tropical humid lowland forests and this picture was taken at night in a humid lowland forest at beautiful Drake Bay, Costa Rica. Its skin is granulated with a bright red head, body and upper arms and bluish-green underparts, legs and lower arms. The granular poison frogs are toxic to predators and possess aposematism coloration like the bold red colors that may serve as a warning to would-be predators. Species that evolve a wide range of characteristics to avoid being selected and captured by predators are known to have adapted predator defenses such as aposematism. Dendrobatids produce some of the most toxic alkaloid poisons known. Scientists are unsure of the source of the poison dart frog’s toxicity but it is possible they absorb plant poisons that are carried by their prey, including ants, termites and beetles.
