The Philippine slow loris is one of the smallest slow lorises, distinguished by pale golden to reddish fur, no markings on the head and no second upper incisor. Like other slow lorises it has a vestigial tail, a round head, short ears, a broad flat face with large eyes, and a grooming claw on the second toe of the hind foot. A gland on the arm produces an oily toxin used in defence. It was first described in 1893 from Tawi-Tawi in the Philippines and is also called the Bornean slow loris (Wikipedia, general species account).
It is arboreal and nocturnal, lives at low densities and is very hard to find; it is probably one of the more insectivorous slow lorises. In the Philippines it is known from the Sulu Archipelago, not from Mindanao or Jolo, and local people report it in calamansi trees. It may have disappeared from some islands, and two zoologists suggested in 1985 that the Philippine animals might have been introduced. Illegal wildlife trade and habitat loss are the main threats. It is a rare, localised species on this guide, not one to plan a trip around (Wikipedia, citing published sources).
