Hyperoliids are the Sedge and Bush Frogs of Africa, Madagascar, and Seychelles Islands. The genus Hyperolius (Reed and Lily frogs) has more than 100 species of small, often brightly colored and polymorphic species. The genus Kassina has medium-sized species that prefer to walk and even run in place of hopping. Leptopelis tend to be more properly "tree" frogs, whereas Hyperolius frequent sedges and rushes. Tornierella are specialized snail-eaters (Drewes and Roth, 1981). There are three subfamilies: Hyperoliinae, Kassininae, and Leptopelinae.
