Limnonectes is a genus of fork-tongued frogs of 91 known species, but new ones are still being described occasionally. [1] [2] They are collectively known as fanged frogs because they tend to have unusually large teeth, which are small or absent in other frogs.

Contents

Habitat

These frogs are found throughout East and Southeast Asia, most commonly near forest streams. Multiple species of Limnonectes may occupy the same area in harmony. [3] Large-bodied species cluster around fast rivers, while smaller ones live among leaf-litter or on stream banks. The Indonesian island of Sulawesi is home to at least 15 species of this frog, only four of which have been formally described. [4]

Lifecycle

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. [5] The tadpoles of the corrugated frog (L. laticeps) are free-swimming but endotrophic, meaning they do not eat but live on stored yolk until metamorphosis into frogs. [5] 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. [6] L. larvaepartus is the only known species of frog that gives live birth to tadpoles. [4] Parental care is performed by males. [3]

<i>Leptobrachella</i> Genus of amphibians

Leptobrachella is a genus of frogs in the family Megophryidae. Members of Leptobrachella are found throughout Asia including on Borneo and the Natuna Islands. They are sometimes referred to as Borneo frogs, slender-armed frogs, or dwarf litter frogs. The genus contains over 82 species with 25 found in China alone.

<i>Philautus</i> Genus of amphibians

Philautus is a genus of shrub frogs in the family Rhacophoridae from Asia. Some species in this genus are now considered extinct by IUCN, while others are widespread and abundant. The taxonomy of the group is unclear, with many poorly described species.

<i>Meristogenys</i> Genus of amphibians

Meristogenys is a genus of true frogs from Borneo. Its tadpoles are adapted to fast-flowing mountain streams and easily recognizable by their divided upper lip with ribs on the outside.

<i>Occidozyga</i> Genus of amphibians

Occidozyga is a genus of frogs in the family Dicroglossidae found in southeastern Asia between eastern India, southern China, and Java. They sometimes go under the common name Java frogs or floating frogs.

<i>Staurois</i> Genus of amphibians

Staurois is a small genus of minuscule true frogs. Most species in the genus are restricted to Borneo, but two species are from the Philippines. This genus is a quite ancient member of the true frog family, Ranidae. They are typically found in or near rapidly flowing, small rocky streams, and are sometimes known as splash frogs or foot-flagging frogs. The latter name refers to their unusual behavior of conspicuously waving their hindlegs and feet, as a way of signalling other members of the species. Similar behavior has also been documented in other frog genera, notably Hylodes and Micrixalus.

<i>Kalophrynus</i> Genus of amphibians

Kalophrynus is a genus of microhylid frogs. It is the only genus in the subfamily Kalophryninae. The species in this genus are found in southern China, in Southeast Asia to Java and Philippines, and in Assam, India.

<i>Leptolalax</i> Genus of amphibians

Leptolalax is a genus of frogs in the family Megophryidae. They are sometimes known as Asian toads, metacarpal-tubercled toads, or slender litter frogs, although many species-specific common names do not follow these conventions, and many species do not have common names. They are widely distributed in southeastern and eastern Asia, from southern China and northeastern India to the Malay Peninsula and Borneo. Leptolalax are typically small and have a cryptic colour pattern and no obvious morphological characters useful in systematic studies. Consequently, both molecular genetic analyses and analysis of advertisement calls by male frogs have been important in identifying new species.
