The following genera are recognised: * Subfamily Alcalinae Brown, Siler, Richards, Diesmos, and Cannatella, 2015 ** '' Alcalus'' (5 species) * Subfamily Ceratobatrachinae Boulenger, 1884 **'' Cornufer'' Tschudi, 1838 (> 50 species) **''

Platymantis ''Platymantis'' is a genus of frogs in the family Ceratobatrachidae. They are commonly known as wrinkled ground frogs, ground frogs, and forest frogs. As currently defined, ''Platymantis'' is a large genus with up to as many as 60 species fou ...

'' Günther, 1858 (> 30 species) * Subfamily Liuraninae Fei, Ye, and Jiang, 2010 **'' Liurana'' Dubois, 1987 (4 species) Formerly, the following genera were also recognized in the family Ceratobatrachidae, but have now been merged into the genera above. *'' Batrachylodes'' Boulenger, 1887 (8 species) *'' Palmatorappia'' Ahl, 1927 (1 species) *'' Ceratobatrachus'' Boulenger, 1884 (1 species) *'' Discodeles'' Boulenger, 1918 (5 species)

Life history

All Ceratobatrachidae lay eggs outside of water and undergo

direct development Marine larval ecology is the study of the factors influencing dispersing larvae, which many marine invertebrates and fishes have. Marine animals with a larva typically release many larvae into the water column, where the larvae develop before met ...
