The dancing frogs ( Micrixalus ) are a genus of small frogs that are endemic to the Western Ghats in western India .

features

The frogs are small with body lengths of 2.5 to 3.5 cm. In most cases, they are brownish or reddish brown in color and have relatively smooth skin. The eardrum is small. The hind feet are webbed while the fingers of the front feet are free. The characteristic features used for a diagnosis of the genus concern the shoulder girdle . They usually have an omosternum, an element of the sternum that protrudes through the collarbones (firmisternal shoulder girdle), which usually has a point made of cartilage and is not forked in the dancing frogs. In addition, the epicoracoid cartilages have grown together at the front and back.

Way of life

Dancing frogs live in mountain rainforests near fast flowing streams and rivers. They prefer to stay on wet stones near the water. The males are territorial and mark their territory and woo females by shouting and conspicuously wagging their hind legs. The dancing frogs lay their spawn directly on the bank on stones that are located within the splash zone or buried in the bottom of the water. The dancing frog tadpoles have remained unknown for more than 125 years since the genus was described in 1888. They are elongated like eels, have a powerful tail and are up to 3 cm long. The tadpoles live like earthworms in sandy or gravelly banks, in the bottom of the water or in sandbars, usually at depths of 10 to 40 centimeters and feed on organic particles that they find in the soil.

Systematics

The genus Micrixalus was introduced in 1888 by the Belgian-British zoologist George Albert Boulenger . The type species is Ixalus fuscus Boulenger, 1882 . In 2001 the dancing frogs were placed in a subfamily Micrixalinae within the family of the real frogs (Ranidae) and in 2006 this subfamily was raised to the family rank as part of an extensive phylogenetic study of the amphibians. The Micrixalidae are the sister group of the Ceratobatrachidae .
