Much of the information on this family comes from the most famous member, the Goliath frog (Conraua goliath), which is the largest known species of frog. Individuals may weigh up to 4 kilograms (8 lbs) and up to 32 cm snout-vent length. These species are poorly known and many are consumed for food.

The closest sister group to Conrauidae is likely Petropedetidae (both were formerly subfamilies to Ranidae) as summarized by Blackburn and Wake (2011).
