Did you know…?

  • It is one of the few venomous primates: its saliva, mixed with a secretion from its arm, causes severe reactions.

    From Bengal Slow Loris

  • It is one of the few venomous primates known: it mixes the secretion of a gland on its elbow with its saliva, and its bite can cause anaphylactic shock in people.

    From Bengal Slow Loris

  • Animals caught for the pet trade have their teeth pulled out with pliers, which usually condemns them to die of infection.

    From Bengal Slow Loris

  • It is one of the few venomous primates: a gland on its arm produces a toxic secretion it mixes with saliva before biting.

    From Greater Slow Loris

  • Unlike the slow loris it is quicker and more restless, and lives mainly in Sri Lanka and southern India.

    From Red Slender Loris

  • 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.

    From Red Slender Loris

  • 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.
