Fejervarya cancrivora
Encyclopedia
The Crab-eating Frog formerly (Rana cancrivora), is a frog
native to south-eastern Asia
including the Philippines
and more rarely as far west as Orissa
in India. 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.
