Slow Loris

Slow lorises are nocturnal, arboreal strepsirrhine primates in the genus Nycticebus, found in South and Southeast Asia.

Slow lorises are nocturnal, arboreal strepsirrhine primates in the genus Nycticebus, found in South and Southeast Asia. They are the only venomous primates known, and most species are threatened by habitat loss and the wildlife trade. These small, tree-dwelling primates are omnivores with distinctive facial markings.

Taxonomy and species

Slow lorises belong to the genus Nycticebus in the family Lorisidae. Sources differ slightly on the exact number of recognized species, but at least eight are commonly cited, with conservation status varying among them.

Physical characteristics

Slow lorises are compact, big-eyed primates adapted for nocturnal life. They have short snouts, dense fur, and distinctive facial markings. Their grasping hands and feet and cautious movement suit an arboreal lifestyle.

Behaviour and diet

These primates are mostly solitary and active at night. Their diet is broad and includes fruit, tree gums, nectar, insects, small birds, reptiles, eggs, and other small animals.

Venom and defence

Slow lorises are unusual among primates because they are venomous. They produce a toxic bite associated with glands on the upper arm, and bites can cause severe reactions in humans.

Conservation

Slow lorises are declining across much of their range. Major threats include deforestation, habitat degradation, and capture for the wildlife and pet trades.
