Ha Long Roundleaf Bat

The Ha Long leaf-nosed bat is a species of bat in the family Hipposideridae, endemic to Vietnam. It is found only in the karst habitats of north-eastern Vietnam and is primarily a cave-dweller, although it is also known to be spotted in forests, from an altitude of 3 to 523 m (Wikipedia, general species account).

Of the two subspecies, Bourret's leaf-nosed bat is found in the Cat Ba and Bai Tu Long national parks, and Sung's leaf-nosed bat is found in the Cuc Phuong and Ba Be national parks and the Huu Lien and Na Hang nature reserves.
