Oophaga

Not to be confused with oophagy.

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 El Chocó 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] Most species in this genus are seriously threatened and O. speciosa is already extinct.^[6]

Etymology

Oophaga, Greek for "egg eater" (oon, phagos),^[7][8] is descriptive of the tadpoles' diet.^[9][10]

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.^[11]

There are twelve species in this genus:^[2]

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]
