The slow lorises are three species of loris and are classified as the genus Nycticebus. These slow moving strepsirrhine primates range from Borneo and the southern Philippines in Southeast Asia, through Bangladesh, Vietnam and Thailand.

Adult slow lorises range in size from 21 to 38 cm, depending on the species, and weigh up to 2 kilograms. The tail is a mere stump. The short, thick fur can have a variety of color, mostly grey-reddish and often with whitish undetones. They have well developed thumbs, which they use to grasp and hold fast to branches, and a very flexible back. The eyes are large and point forward, and the ears are small and nearly hidden in the fur. They are generally more strongly built than the slender lorises.

Like all lorises, slow lorises are diurnal and arboreal animals that prefer the tops of the trees. Also, they have slow, deliberate movements and a powerful grasp that makes them very difficult to remove from branches. They live as solitaries or in small family groups, and mark their territory with urine.

Slow lorises can produce a toxin which they mix with their saliva and use as protection against enemies. Mothers will lick this toxin onto her offspring before leaving them to search for food.

Slow lorises are happenstance carnivores, typically eating insects, bird eggs and small vertebrates. With their slow quiet movements, they creep to their prey, in order to then catch it with a lightning-quick snatch. They also eat fruits, but rarely.

After an approximately 190 day gestation, the female births one (or rarely two) young. The newborn clasps itself to the belly of the mother or the father. When it is older it will be "parked" on a branch while its parent searches for food. After approximately nine months they are weaned. The life expectancy of the slow loris is up to 14 years.
