The muzzle is larger and less pointed than the red slender loris. This has contributed greatly to the decline of the slender loris. Little-known ones like the Slender loris also occur here. This slender loris is an endangered species. The nocturnal slender loris could be common but is seldom seen. The slender loris has small finger nails on its digits. There are also Jerdon's palm civet, gray slender loris, great pied hornbills and king cobras. The primate species red slender loris, tufted gray langur, and purple-faced langur are seen also. The gray slender loris ("Loris lydekkerianus") is a species of primate in the family Loridae. The slender loris is an arboreal animal, spending most of its life in trees.
