As their name suggests, pygmy slow lorises are the smallest of the eight species of slow loris. On average, adults measure around 20 cm in length and weigh approximately 0.5 kg, although this can fluctuate substantially with the seasons.
The pygmy slow loris has a reddish-brown coat with pale faces except for reddish-brown markings around their eyes. One of their most notable features is their large, round eyes, typical of nocturnal primates who need to see well in the dark.
Pygmy slow lorises are nocturnal and forage at night. They can spend up to an incredible 19 hours sleeping each day and tend to sleep curled up in a ball in the hollows of trees or on branches. During winter, pygmy slow lorises can become inactive for extended periods of time, slipping into a torpor in order to save energy when food is less available.
IUCN Red List status: Vulnerable
The pygmy slow Loris is listed as Vulnerable as the species is believed to have undergone a decline of more than 30% over the last three generations due primarily to hunting, but also as a result of habitat loss.
