The Hyperoliidae, sedge and bush frogs, are a large family of small to medium-sized, brightly colored frogs which contains more than 250 species in 19 genera. Seventeen genera are native to sub-Saharan Africa.〔Shiotz, 1999〕 In addition, the monotypic genus ''Tachycnemis'' occurs on the Seychelles Islands, and the genus ''Heterixalus'' (currently 10 species) is endemic to Madagascar. Hyperoliids range from in body length. Many species have smooth, brightly patterned skin that almost looks enameled. Most hyperoliids are arboreal, but some are terrestrial, including several ''Kassina'' species that move by walking or running rather than hopping. Diets vary widely, with examples including ''Tornierella'', which specializes on snails, and ''Afrixalus fornasini'', the only terrestrial frog known to prey on eggs of other species of anurans. Breeding in this family begins at the start of the rainy season, where hyperoliids congregate at breeding sites. Most hyperoliids lay their eggs in water, although foam nesting, tree-hole breeding, and laying of eggs in vegetation above water are all known behaviors.〔 ''Afrixalus'' builds leaf nests for its eggs, by folding and gluing the edges of the leaves. Tadpoles are pond type larvae with large dorsal fins on their tails. No fossil hyperoliids are known. ==Classification== Family HYPEROLIIDAE * Subfamily Hyperoliinae * * Genus ''Acanthixalus'' - African wart frogs * * Genus ''Alexteroon'' - midwife frogs * * Genus ''Arlequinus'' - Mebebque frogs * * Genus ''Callixalus'' - African painted frogs * * Genus ''Chlorolius'' - Koehler's green frogs * * Genus ''Chrysobatrachus'' - Itombwe golden frogs * * Genus ''Cryptothylax'' - wax frogs * * Genus ''Heterixalus'' - Madagascan reed frogs * * Genus ''Hyperolius'' - African reed frogs * * Genus ''Nesionixalus'' * Subfamily Kassininae * * Genus ''Afrixalus'' - banana frogs * * Genus ''Kassina'' - running frogs * * Genus ''Kassinula'' - clicking frogs * * Genus ''Opisthothylax'' - grey-eyed frogs * * Genus ''Paracassina'' - common striped frogs * * Genus ''Phlyctimantis'' - African striped frogs * * Genus ''Semnodactylus'' - Weal's frogs * * Genus ''Tornierella'' * Subfamily Tachycneminae * * Genus ''Tachycnemis'' - Seychelles Islands frogs 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Hyperoliidae」の詳細全文を読む スポンサード リンク
