Where the name “Sunda slow loris” comes from
“Sunda” in its English name refers to the Sunda Islands, where it lives. The scientific name “coucang” comes from “kukang,” its common name in Indonesia.
University of Michigan Animal Diversity WebIt is a primitive primate from Southeast Asia, and unusually for a mammal, it is venomous.
It has noticeable dark rings around its eyes and a whitish stripe running from its forehead to the tip of its nose.
Gripping branches firmly with its hands and feet, it moves slowly through the trees, making very little noise.
How the Sunda slow loris lives
It is mainly active at night. It feeds on sap, nectar, plant stems and fruit, among other foods. It generally spends much of its time apart from other individuals.
