Slender lorises  (Loris tardigradus and Loris lydekkerianus)

Slender lorises are nocturnal and arboreal, spending daylight hours sleeping on branches or hollow trees (6). By night they move slowly and stealthily in the trees, and catch their prey by quietly stalking it and grabbing it with two hands. Slender lorises have large eyes which provide them with excellent night vision and, like the lemurs, have an excellent sense of smell (5). The muzzle is elongated with an area of moist, glandular skin around the nostrils (2), and it is this that heightens their sense of smell which is useful for foraging. Their diet consists of insects, small vertebrates, birds’ eggs, fruit, shoots and young leaves (5). To maximize protein and nutrient uptake, lorises consume every part of their prey including the scales and the bones (4).

These prosimians usually live alone or with a mate. Females enter oestrous twice a year and are receptive for about a week (5). The gestation period lasts for 166-169 days, after which the female gives birth to one or two young (5). Males leave their natal area at maturity to establish their own territories, though female offspring typically stay within their mother’s territory, and only leave to establish their own range when they become reproductively active (5).
