Active during the night, the Bengal slow loris can be found stalking through the trees with slow, deliberate movements as it searches for food (6). Its diet is varied, consisting mainly of plant exudates such as gums and resins, but also nectar, fruits, insects, bark and bird eggs (9).
One of the more curious aspects of slow loris biology is the production of a toxic substance from glands on the insides of the elbows. This toxin, secreted in sweat, is licked off the gland and mixed with saliva (activating the toxin) where it appears to be channelled up the fine comb-like teeth at the front of the mouth. When defending itself, the loris’s bite may transmit this poison, and people who have been bitten have reported it to be particularly painful, with anaphylactic shock occurring in some cases (7).
Little is currently known about the social behaviour or reproductive biology of the Bengal slow loris in the wild (2).
