The crab-eating frog ( Fejervarya cancrivora) is a frog native to south-eastern Asia including Taiwan,[Tanjung RD, Kusrini MD, Mardiastuti A, Yustian I, Setiawan A, Iqbal M. 2023.

Biodiversitas 24: 6836-6843.] the Philippines and more rarely as far west as Orissa in India.[ Rare species of frog, snake in Orissa] It has also been introduced to Guam, most likely from Taiwan.[Wostl, Elijah, Eric N.

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.
