A terrapin is one of several small species of turtle living in fresh or brackish water.
The northern river terrapin (Batagurbaska) is a species of riverine turtle native to Southeast Asia.
It is classified “Critically Endangered” by the IUCN
The species is currently found in Bangladesh (in the Sundarbans), India (parts of West Bengal & Odisha), Indonesia, Cambodia and Malaysia.
The northern river terrapin is omnivorous and prefers freshwater habitats.
It moves to brackish river mouths or estuaries in the breeding season (December–March), returning after laying their eggs.
A captive conservation breeding programme has been implemented in Sunderbans Tiger Reserve to protect the species against natural risks and also facilitate genetic management.
