Slow Loris ID

The name Little Fireface comes from the Sundanese name for slow loris – muka geni. In other languages, loris means thin one, wind monkey (both in Sumatra and Thailand),  forest baby, and the shy one.

Eight slow loris species are currently recognised! They are found from the Northeast of India to the Philippines. Two closely related slender lorises are found in India and Sri Lanka. Many more species are likely to be discovered.

The table below shows their distribution and body weight ranges; sadly we do not yet have this information for Borneo’s new loris species as they have rarely been seen in the wild; it will be updated when available.
