Red Slender Loris

Loris tardigradus

Endangered

At very high risk of extinction in the wild in the near future.

Spotted something wrong?

The red slender loris is a tiny nocturnal primate endemic to Sri Lanka, with extremely thin limbs, a slender body and enormous, staring eyes. It feeds almost entirely on insects, which it catches with a surprisingly quick movement after approaching in slow motion. It lives in the wet half of the island, in forests that have been drastically reduced by farming and tea plantations. It is one of the priority species of the EDGE programme for its evolutionary distinctiveness.

Fun facts

  • comportamientoUnlike the slow loris it is quicker and more restless, and lives mainly in Sri Lanka and southern India.
  • It smears urine on its hands and feet before climbing, a behaviour called urine washing that serves to leave scent trails along its usual routes and, perhaps, to improve its grip.
  • Its eyes are enormous in proportion to its skull and set so close together that they give it excellent stereoscopic vision in the dark, essential for judging leaps between thin branches.
