The Crab-eating Frog (Fejervarya cancrivora), formerly (Rana cancrivora), is a frog native to south-eastern Asia including the Philippines and more rarely as far west as Orissa in India.^[2] It inhabits mangrove swamps and marshes and is the only known modern amphibian which can tolerate salt water. It is locally favored for its eating quality and is often farmed for its edible legs. Call described as "…dododododok …dododok."

This frog can tolerate marine environments (immersion in sea water for brief periods or brackish water for extended periods) by increasing urea production and retention, and by remaining slightly hyperosmotic within urea and sodium flux.^[3][4][5]
