Conservation Status

The Golfodulcean poison frog (Phyllobates vittatus), is a species of frog in the Dendrobatidae family. It is endemic to Costa Rica. Its natural habitats are subtropical or tropical, moist, lowland forests and rivers. It is threatened by habitat loss.


Phyllobates vittatus is a fairly large poison frog, reaching a length of 3.5 cm in adulthood, with females typically being larger than males. They are more smooth-bodied than other species of the genus, having almost perfectly sloping backs. Unlike the related Phyllobates bicolor and Phyllobates terribilis, their shoulder blades are usually not visible beneath their skin, giving the frogs the appearance of being overweight. The frog's color is black, but it may appear to glitter due to chemical pigments in the skin. Its legs are mottled blue, and the sides often have a marble pattern of blue or green. One of the most distinctive features of Phyllobates vittatus are the two stripes running down its back for which it was named. These stripes are usually fire orange, but they may also be golden, yellow, or green, and extend from just above the cloaca to the end of the frog's nose.


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.

As Pets[]

  • See also: History of Dendrobatid Frogkeeping

Golfodulcean poison frogs are communal animals, and have recently become available in the pet trade. They can be kept in a vivarium measuring about 100x60x60 cm, to grant the frogs both space to move around on the ground and space to climb. A clean, mossy substrate should be provided and, optionally, a carpet of leaves. However, care must be taken to ensure that the leaves are completely unblemished, as many parasitic fungi are lethal to amphibians. Phyllobates frogs climb by sticking to leaves with their adhesive toe pads, in a similar manner to geckos, and the climbing space must be smooth and vertical. Phyllobates frogs are more than capable of climbing out of unsecured vivaria, so their vivaria must be completely sealed.
