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 millennia. 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.The body of Nasikabatrachus sahyadrensis appears robust and bloated and is relatively rounded compared to other more dorsoventrally-flattened frogs. Its arms and legs splay out in the standard anuran body form. Compared to other frogs, N. sahyadrensis has a small head and an unusual, pointed snout. Adults are typically dark purplish-grey in color. Males are about a third of the length of females.
