Callulina (commonly known as the warty frogs) is a small genus of frogs in the family Brevicipitidae. There are nine species in this genus. They live in Tanzania and Kenya. For a long time, scientists thought that there was only one species in Callulina, a frog that lives in the Eastern Arc Mountains in Tanzania and in southern Kenya. However, they found eight more species. Most of these frogs are in danger of dying out.
