Gray slender loris
The gray slender loris is a nocturnal primate found across South Asia, particularly in parts of India and Sri Lanka. It occupies a range of habitats including dry forests, scrubland, and even plantations, where its slim body and agile limbs allow it to move quietly among branches at night. Its large forward‑facing eyes and distinct dark eye rings give it excellent night vision, essential for its slow, stealthy lifestyle.
Our male, Ninja, lives in the Wildlife at Night exhibit at the front of the zoo, sharing his enclosure with our Bettong.

About the gray slender loris
This species is primarily insectivorous, feeding on insects, spiders, and small vertebrates. Using a precise, deliberate style of movement, the gray slender loris stalks its prey silently before making a quick grab. Its flexible hands and specialised grip help it cling securely to branches while hunting.
Gray slender lorises are largely solitary, with individuals occupying overlapping home ranges. They communicate through vocal calls and scent marking, and mothers care for their single offspring after a gestation of around 160 to 170 days.
Conservation
The gray slender loris is classified as Endangered by the IUCN. Populations across India and Sri Lanka are under pressure from habitat loss, forest fragmentation, and illegal wildlife trade, particularly for the pet trade and traditional medicine. Conservation efforts focus on strengthening law enforcement, raising public awareness, and protecting remaining habitats to safeguard wild populations.
