Bengal Slow Loris (Nycticebus bengalensis) — wildlife photography in India

About this species

The Bengal slow loris is one of the few venomous primates on Earth, delivering a toxin from glands on its inner elbow that it mixes with saliva. By day it curls into an near-invisible ball high in the canopy; by night its huge reflective eyes and painstakingly slow, deliberate movement through the branches make it one of Northeast India's most sought-after nocturnal sightings. Night-spotlighting for the venomous, slow-moving Bengal slow loris in Northeast India.

Behavior

Strictly nocturnal and almost entirely arboreal, moving hand-over-hand through the canopy with such deliberate slowness that it rarely snaps a twig. Solitary and territorial, marking routes with scent.

Diet

Gum and sap tapped from tree bark, fruit, insects, and occasionally small vertebrates or eggs.

When and Where to Photograph Bengal Slow Loris

Join a guided night walk with a spotlight — look for a pair of bright, round eyeshine reflecting back from the mid-to-upper canopy, then hold the light steady rather than following movement, since the loris moves too slowly to lose the beam.

Plan field days around Jan–Dec: light is often strongest at dawn and dusk, when many mammals and birds are most active. Work with a naturalist who knows local movement patterns — they will position you ethically while improving your odds of a encounter in Namdapha National Park.
