Oophaga
Oophaga is a genus of poison-dart frogs containing nine species, many of which were formerly placed in the genus Dendrobates.[1] The frogs are distributed in Central and South America, from Nicaragua through the Colombian El Choco to northern Ecuador (at elevations below 1,200 m (3,900 ft)).[1][2] Their habitats vary with some species being arboreal while other being terrestrial,[3] but the common feature is that their tadpoles are obligate egg feeders.[3][1][4]

Etymology
Oophaga, Greek for "egg eater" (oon, phagos),[5][6] is descriptive of the tadpoles' diet.[7][8]
Reproduction
While presumably all dendrobatids show parental care, this is unusually advanced in Oophaga: the tadpoles feed exclusively on trophic (unfertilized) eggs supplied as food by the mother; the father is not involved.[1][4] Through the eggs, the mother also passes defensive toxins to the tadpoles: Oophaga pumilio tadpoles experimentally fed with eggs from alkaloid-free frogs did not contain alkaloids.[9]
Species
There are nine species in this genus:[2]
Image | Scientific name | Common name | Distribution |
---|---|---|---|
Oophaga arborea (Myers, Daly, and Martínez, 1984) | Polkadot poison frog | Panama | |
Oophaga granulifera (Taylor, 1958) | Granular poison frog | Costa Rica and Panama | |
Oophaga histrionica (Berthold, 1845) | Harlequin poison frog | El Chocó region of western Colombia | |
Oophaga lehmanni (Myers and Daly, 1976) | Lehmann's poison frog | western Colombia | |
Oophaga occultator (Myers and Daly, 1976) | La Brea poison frog | Cordillera Occidental in the Cauca Department of Colombia | |
Oophaga pumilio (Schmidt, 1857) | Strawberry poison-dart frog | eastern central Nicaragua through Costa Rica and northwestern Panama | |
Oophaga speciosa (Schmidt, 1857) | Splendid poison frog | Cordillera de Talamanca, western Panama | |
Oophaga sylvatica (Funkhouser, 1956) | Diablito poison frog | southwestern Colombia and northwestern Ecuador. | |
Oophaga vicentei (Jungfer, Weygoldt, and Juraske, 1996) | Vicente's poison frog | Veraguas and Coclé Provinces of central Panama | |
Captivity
Oophaga are kept as pets, but they are challenging to breed in captivity. Oophaga pumilio, however, is easier to breed and popular.[3]
