Cynopterus brachyotis

The lesser short-nosed fruit bat (Cynopterus brachyotis) is a species of megabat within the family Pteropodidae. It is a small bat that lives in South and Southeast Asia and Indonesia (Borneo). It weighs between 21 and 32 grams (0.74 and 1.13 oz), and/or 70 to 127 mm. It occurs in many types of habitat, but most frequently in disturbed forest, including lower montane forest and tropical lowland rain forest, plus gardens, mangroves, and vegetation on beaches. Lesser short-nosed fruit bats are generally brown to yellowish brown with a brighter collar. Adult males have dark orange collars whereas adult females have yellowish collars. An indistinct collar is observed in some immature bats. The edges of the ears and the wing bones are usually white. Individuals have two pairs of lower incisors, a fox-like face and large dark eyes. The head and body length is 7–8 cm (2.8–3.1 in), the forearm length is 6–7 cm (2.4–2.8 in), tail length is 0.8–1.0 cm (0.31–0.39 in), and ear length is 1.4–1.6 cm (0.55–0.63 in). There are nine subspecies of lesser short-nosed fruit bat. Corbet and Hill listed 19 alternate names of C. brachyotis, which include: Pachysoma brachyotis, P. duvaucelii, P. brevicaudatum, P. luzoniense, C. grandidieri, C. marginatus var. scherzeri, C. marginatus var. ceylonensis, C. marginatus var. philippensis, C. marginatus var. cuminggii, C. marginatus var. andamanensis, C. brachyoma, C. montanoi, C. minutus, C. minor, C. babi, C. archipelagus and C. nusatenggara. Kitchener and Maharadatunkamsi considered luzoniensis and minutus as separate species while Hill and Thonglongya transferred angulatus to C. sphinx. The lifespan of the lesser short-nosed fruit bat is approximately 20 to 30 years.
