Like all Lorises, the Pygmy Slow Loris is nocturnal, arboreal and endangered. It is native to forests of Cambodia, Vietnam and Laos.
Threats include hunting, trade and habitat destruction. It is related to several other species of Slow Loris native to Southeast Asia.
Lorises groom themselves with a "tooth comb" - their top front teeth are comb-like.
Slow Lorises are unusual for mammals in producing a poisonous toxin - the only primates to do so - by licking a gland
on their arm and mixing the secretion with saliva.
