Oophaga is a genus of poison-dart frogs containing twelve species, many of which were formerly placed in the genus Dendrobates.[1] The frogs are distributed in Central and South America, from Nicaragua south through the Colombian regions of El Chocó and Pacífico 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][5]

Etymology

Oophaga, Greek for "egg eater" (oon, phagos),[6][7] is descriptive of the tadpoles' diet.[8][9]

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.[10]

Species

There are twelve species in this genus:[2]

Scientific name	Common name	Distribution
Oophaga anchicayensis (Posso-Terranova and Andrés, 2018)		Chocó region of northwestern Colombia

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 or “blue-jeans” frog	eastern central Nicaragua through Costa Rica and northwestern Panama
Oophaga solanensis (Posso-Terranova and Andrés, 2018)		Northwestern region of Colombia, on the western banks of the Atrato and san Juan rivers.
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 may be kept as pets by experienced amphibian keepers, but they are challenging to breed in captivity as only parents can feed and care for tadpoles.[3]
