Kassina is a genus of hyperoliid frogs, commonly referred to as running frogs or kassinas. They are found throughout sub-Saharan Africa.[1] They are characterized by preferring a distinctive "walking" with the back legs instead of the more traditional frog-hopping.[2]


There are 16 recognized species in the genus Kassina:[1][3]

In captivity[edit]

K. maculata is frequently exported from Tanzania for the exotic pet trade.


It is the source of "kassinin", a frequently studied tachykinin peptide.[4]
