Naked Bat (Cheiromeles torquatus)
Medium small to large bats distinguished by their thick tail which protrudes for well over half its length from the interfemoral membrane. The muzzle lacks a noseleaf and projects well beyond the lower jaw. Lips often somewhat wrinkled. Ears thick, sometimes joined over the top of the head by a band of skin. Wings long and narrow.
Premaxillary bones of skull well developed and attached to the palate and the maxillaries, forming small foramina.

Identification: Body almost completely naked except for scattered short hairs and a cluster of long hairs around a scent gland in its neck. Bare skin of body dark grey. In flight can often be recognized by its large size, strong flight and the audible clicking of its echolocation call as it searches for insects. Exposed tail and large separate ears can sometimes be seen as well.
