Wildlife of Danum · The slow one

Bornean slow loris

Nycticebus menagensis

A round-eyed, deliberate night-mover that creeps hand-over-hand through the understorey — and hides one of the animal kingdom's few venomous bites.

The animal

Field notes

Where the tarsier darts, the slow loris oozes — a careful, hand-over-hand creep through the branches that makes it easy to miss and hard to forget. Big forward-facing eyes throw back a strong orange eyeshine, which is usually how guides find one, motionless, mid-reach.

It carries a genuine oddity: a toxin secreted at the elbow, drawn into the mouth to deliver a venomous bite — one of very few mammals that can make that claim. You'll admire it from a respectful distance, torchlight low, which is how it should be.

Where & when in Danum

Understorey and mid-storey on the night walks at both forest lodges; slower, quieter stretches of trail are best.

Best odds

Year-round on night walks; a soft torch and a patient guide beat any calendar.
