Conraua

Conraua, known as slippery frogs or giant frogs is a genus of large frogs from sub-Saharan Africa. Conraua is the only genus in the family Conrauidae. Alternatively, it may be placed in the family Petropedetidae.

This genus includes the largest frog of the world, Conraua goliath, which may grow to 32 cm in snout–vent length and weigh as much as 3.3 kg. Four of the seven species in this genus are threatened.

Etymology
