Loris is the common name for the strepsirrhine primates of the subfamily Lorinae in family Lorisidae. Loris is one genus in this subfamily and represents the slender lorises, while Nycticebus is the genus for the slow lorises. MSW3 Groves Lorises are nocturnal. They are found in tropical and woodland forests of India, Sri Lanka, and southeast Asia. Loris locomotion is a slow and cautious climbing form of quadrupedalism. Some lorises are almost entirely insectivorous, while others also include fruits, gums, leaves, and slugs in their diet.

Female lorises practice infant parking, leaving their young infants behind in nests. Before they do this they bathe their young with allergenic saliva that is acquired by licking patches on the insides of their elbows that produce a mild toxin that discourages most predators.

The family Lorisidae is found within the infraorder Lorisiformes with the family Galagidae, the galagos. This infraorder is a sister taxon of Lemuriformes, the lemurs. Within Lorinae, there are five species of lorises in two genera.
