Oophaga sylvatica, sometimes known as its Spanish name diablito, is a species of frog in the family Dendrobatidae found in Southwestern Colombia and Northwestern Ecuador.[3] Its natural habitat is lowland and submontane rainforest; it can, however, survive in moderately degraded areas, at least in the more humid parts of its range. It is a very common frog in Colombia, but has disappeared from much of its Ecuadorian range. It is threatened by habitat loss (deforestation) and agricultural pollution. It is sometimes seen in the international pet trade.[1]
This species occurs in several color morphs. For example, the Bilsa Biological Station (operated by the Jatun Sacha Foundation) boasts three color morphs—red, yellow, and orange—within their 3000-ha protected area located within Ecuador's Mache and Chindul coastal mountain ranges.[citation needed]
Toxins
Oophaga sylvatica feed on insects such as ants and mites that contain lipophilic alkaloid toxins, and these toxins are then absorbed by the frog and used as a defense mechanism.[4] These frogs cannot produce the toxins by themselves. Proteomic profiling has revealed that the livers of these frogs produce high levels of specialized proteins like saxiphilin that may be involved in alkaloid sequestration.[4] The alkaloids also cause them to give off vibrant colors.[5]
