Limnonectes is a genus of fork-tongued frogs. There are about 61 known species, but new ones are still being described occasionally.[1] They are collectively known as fanged frogs because they tend to have unusually large teeth, which are small or absent in other frogs.

Life cycle

Tadpoles of this genus have adapted to a variety of conditions. Most species (e.g. Blyth's River Frog L. blythii or the Fanged River Frog L. macrodon) develop normally, with free-swimming tadpoles that eat food. The tadpoles of the Corrugated Frog (L. laticeps) are free-swimming but endotrophic, meaning they do not eat but live on the stored yolk until metamorphosis into frogs.[2] Before, it was assumed that L. limborgi had direct development (eggs hatching as tiny, full-formed frogs), but more careful observations have showed that L. limborgi has free-swimming but endotrophic larvae; this probably applies to the closely related L. hascheanus too.[3]
