Deichmann, C. Meisner, D. Wheeler. Slender loris cages stay cleaner longer than slow and pygmy loris cages because the build up of body secretions occurs at a faster rate among the larger species (Weisenseel, 1986). 1 of 4 Paula Kolvig, rainforest assistant curator, holds Pygmy Slow Loris twins at Moody Gardens in Galveston. This hibernation-like behavior is observed both in the wild and in captivity. Reports from local people of Cambodia suggest pygmy slow lorises eat mostly termites, tree parts, fruit, and bamboo. Crypto is not typically studied in non-domesticated non-human primates, and little information is available regarding its prevalence. There are ten species of slow loris, of which the pygmy is the smallest. 2008. Populations of pygmy slow lorises drastically declined during the Vietnam War, as bombing, land clearing by Rome plows, and use of Agent Orange (2,4,5-T), other defoliants, and napalm destroyed the majority of their native habitat in Vietnam, Laos, and Cambodia. It lives in thick forest and bamboo groves. It inhabits primary and secondary rainforests as well as degraded habitats, and also occurs in evergreen forest in Laos and bamboo thickets in Vietnam. Prior to the Vietnam War, broad-leafed tropical forests with stands of bamboo and mangroves covered approximately one-half of the land area in these countries. The pygmy slow loris is nocturnal, sleeping by day while gripping a branch with its hands and feet. Primate Adaptation and Evolution. Where is the poverty-environment nexus? Endothermy is a synapomorphy of the Mammalia, although it may have arisen in a (now extinct) synapsid ancestor; the fossil record does not distinguish these possibilities.
