Crab-Eating Frog, Fejervarya cancrivora

The Crab-Eating Frog (Fejervarya cancrivora) formerly Rana Cancrivora, is a frog endemic to south-eastern Asia including Taiwan, China, the Philippines, and more rarely as far west as Orissa in India. It inhabits mangrove swamps and marshes and it is the only known modern amphibian which can withstand salt water. It’s locally favored for its eating quality and is frequently farmed for its edible legs.

This frog can tolerate marine environments by increasing urea production and retention, and by staying slightly hyperosmotic within urea and sodium flux.
