Ghatixalus

genus of amphibians


Ghatixalus is a group of frogs in the family Rhacophoridae, subfamily Rhacophorinae. They live in the Western Ghat mountains, which are in southern India. They are the closely related to the frogs in Chiromantis, Feihyla, Taruga, Polypedates, and Rhacophorus.[2][3] Scientists used the words "Ghats" and "Ixalus" to make the name. "Ghats" is for the Western Ghat mountains and "Ixalus" is for the old name of another group of frogs. Many groups of frogs in Rhacophoridae have ixalus in their names for this reason.[1]

Description

change

Ghatixalus are medium to very large in size. Adult male frogs can be 39–82 mm (1.5–3.2 in) from nose to rear end and adult female frogs 58–67 mm (2.3–2.6 in). The skin of the frog's back is brown with darker brown marks. Eggs develop in foam nests and hatch into tadpoles. These frogs live in mountain streams for their whole lives.[1][3]

Distribution and natural history

change

This frog only lives in Shola forests, so it only lives high up in the Nilgiris and Anaimalai-Palnis, more than 1600 meters above sea level. When people see these frogs, they are usually near streams, sitting on the ground or on grass. Although most frogs in Rhacophoridae are tree frogs, the frogs in Ghatixalus live on the ground.

Species

change

There are only three species in the genus Ghatixalus:[2]

The Palakkad Gap is between the place where G. asterops live and where G. variabilis frogs live. This may be why they became two species.
