| Allen's Slippery Frog, Conraua alleni (Barbour and Loveridge, 1927) can reach 228 mm (9 inches) in body length. This frog, like its relatives can make long, rapid jumps and are very slippery, making them difficult to hang on to. Allen's Slippery Frog ranges from northern Sierra Leone, through southern Guinea and Liberia to southwestern Côte d'Ivoire in West Africa. It occurs from low altitudes to more than 1,000 meters asl. It inhabits fast-flowing permanent streams in hilly rainforest. This is a forest species, and is not found in open habitats. Allen's Slippery Frog is a stream breeder and the tadpoles are usually found in the slow-flowing or nearly stagnant portions of streams. This species is being cultured in captivity.

| The African Water Frogs have long been considered ranid frogs. But, recent molecular evidence suggests they are a monotypic Sub-Saharan African family (see Frost et al. 2006. Bulletin American Museum of Natural History, No. 297). There are two genera and 16 species in this family, and it includes the world's largest frog, the Goliath Frog, Conraua goliath (Boulenger, 1906). |
