Golfodulcean poison frog
The Golfodulcean poison frog (''Phyllobates vittatus'') is a species of frog in the Dendrobatidae family endemic to Costa Rica. Its natural habitats are subtropical or tropical, moist, lowland forests and rivers. It is threatened by habitat loss.
== Poison ==
Like all members of the genus ''Phyllobates'', Golfodulcean poison frogs have highly potent neurotoxic alkaloid poisons in their skin. While it is only the fourth-most toxic of the genus, the Golfodulcean poison frog is still a highly toxic animal. Its poison causes severe pain, followed by tonic-clonic seizures and paralysis if a large enough dose of the toxin is administered. The frog, for protection, advertises its toxin with its multi-coloured body. Because it is of comparatively large size for a poison dart frog, the Golfodulcean poison frog can store a large amount of poison in its skin. Captive examples lack the toxin, which suggests they do not manufacture the poison themselves, but instead acquire it from a species of insect or other small invertebrate on which they feed.
Scientists have not determined the batrachotoxin source for any species of the genus ''Phyllobates'', although toxic birds from New Guinea likely get batrachotoxin from a small beetle of the family Melyridae,.〔Dumbacher, J. P., et al. (2004). "Melyrid beetles (Choresine): A putative source for the batrachotoxin alkaloids found in poison-dart frogs and toxic passerine birds."
