Loris is the common name for the strepsirrhine primates of the subfamily Lorinae (sometimes spelled Lorisinae) in the family Lorisidae. Loris is one genus in this subfamily and includes the slender lorises, while Nycticebus is the genus containing the slow lorises. Lorises are nocturnal. They are found in tropical and woodland forests of India, Sri Lanka, and parts of 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.
