Limnonectes is a genus of fork-tongued frogs of 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.

Lifecycle[edit]

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.[2] 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.[3] Before, L. limborgi was assumed to have direct development (eggs hatching as tiny, full-formed frogs), but more careful observations have showed it has free-swimming but endotrophic larvae; this probably applies to the closely related L. hascheanus, too.[4]
