Nasikabatrachus sahyadrensis (Purple frog)

Wikipedia Abstract

Nasikabatrachus sahyadrensis is a frog species belonging to the family Sooglossidae. It can be found in the Western Ghats in India. Names in English that have been used for this species are purple frog, Indian purple frog, or pignose frog. Although the adult frog was formally described in October 2003, the taxon was recognized much earlier by its tadpole, which had been described in 1918. With its closest relatives in the Seychelles, Nasikabatrachus is thought to have evolved separately for millions of years. Its discovery also adds to the evidence that Madagascar and the Seychelles separated from the Indian landmass sometime well after the breakup of Gondwana had started.

EDGE Analysis

The purple frog is the sole representative of an ancient lineage of frogs that has been evolving independently for over 130 million years. Its closest relatives are the Seychelles frogs, the ancestors of which were present on the Indo-Madagascan land mass with the purple frog’s predecessors when it broke away from the supercontinent of Gondwana 120 million years ago. Formally discovered in 2003, the purple frog spends most of the year underground, surfacing only to breed during the monsoon. It was the first new family of frogs to be discovered since 1926. This species is threatened by ongoing forest loss for coffee, cardamom and ginger plantations.
