Open encyclopedia reference
The crab-eating frog (Fejervarya cancrivora) is a frog native to south-eastern Asia including Taiwan, China, Sumatra in Indonesia, the Philippines and more rarely as far west as Orissa in India. It has also been introduced to Guam, most likely from Taiwan. It inhabits mangrove swamps and marshes and is one of 144 known modern amphibians which can tolerate brief excursions into seawater, and is possibly the only extant marine amphibian.
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. Adults can survive in salt water with salinity as high as 2.8%, and tadpoles can survive salinities as high as 3.9%.
