The Sunda slow loris is further threatened by gathering for illegal traditional medicine.

The Sunda slow loris is found in continuous canopy tropical rainforests.

Despite its slow metabolism rate, the Sunda slow loris has a high-energy diet.

The Sunda slow loris eats insects that other predators avoid due to their repugnant taste or smell.

The Sunda slow loris is nocturnal and arboreal, typically occurring in evergreen forests.

Reproduction is one of the few times the Sunda slow loris aggregates with conspecifics, as it is largely solitary.

Consequently, there has been some disagreement over the identity of Tardigradus coucang; currently the name is given to the Sunda slow loris.

The Sunda slow loris has less white facial coloring than the much smaller pygmy slow loris.

In 1953, all of the slow lorises were lumped together into a single species, the Sunda slow loris (Nycticebus coucang).

The Sunda slow loris is greatly threatened by the pet trade, and is sold as an exotic pet throughout southeast Asia.

It is most closely related to the Sunda slow loris and the Bengal slow loris (N. bengalensis).

The Sunda slow loris is sympatric (shares its range) with the Bengal slow loris in Thailand and hybridisation has occurred.

The Sunda slow loris is found on the Indonesian island of Sumatra as well as Peninsular Malaysia, Singapore, and Thailand.

The Sunda slow loris was first described (in part) in 1785 by the Dutch physician and naturalist Pieter Boddaert under the name Tardigradus coucang.

According to the 2008 International Union for Conservation of Nature (IUCN) Red List assessment, the Sunda slow loris was evaluated as "Vulnerable".

The Javan slow loris is larger than both of the other Indonesian slow lorises, the Sunda slow loris and the Bornean slow loris.

It also provides habitat to some wild animals that are rarely seen in main island Singapore such as the Leopard Cat, Sunda Slow Loris and Sunda Pangolin.

These include Banded Leaf Monkey Presbytis femoralis, Sunda Slow Loris Nycticebus coucang, Malayan Porcupine Hystrix brachura.

In contrast, the Sunda slow loris is characterized by medium width hair anterior to the opening of the ear, and the Javan slow loris always has a diamond stripe between the eyes.

These three subspecies were promoted in 2010 to species status-the Sunda slow loris, the Javan slow loris (N. javanicus) and Bornean slow loris (N. menagensis).

Like other slow lorises, the Sunda slow loris is an arboreal and nocturnal primate, resting by day in the forks of trees, or in thick vegetation and feeding on fruit and insects by night.

The Sunda slow loris (Nycticebus coucang) or greater slow loris is a strepsirrhine primate and a species of slow loris native to Indonesia, western Malaysia, southern Thailand and Singapore.

The proposal covered all three species recognized at the time-the Sunda slow loris, Bengal slow loris, and pygmy slow loris-because they have traditionally been managed collectively owing to a lack of knowledge as to how to distinguish them.

Considered a subspecies of the Sunda slow loris (N. coucang) until 2001, phylogenetic analysis suggests that the Bengal slow loris is most closely related to the Sunda slow loris.

In addition to being smaller than the Bengal slow loris, the sympatric Sunda slow loris also differs in its coloring: it does not have the pale areas of the head, nape and shoulders, and its overall color is a tawny- or golden-brown.

In 1953, all of the slow lorises were lumped together into a single species, the Sunda slow loris (Nycticebus coucang).

In 1939, Reginald Innes Pocock combined all slow lorises into a single species, Nycticebus coucang.

Osman Hill thus listed Nycticebus coucang pygmaeus, while acknowledging that "it may be deemed necessary to accede this form specific rank."

For example, the rapid leaper Tarsius bancanus has semicircular canals much bigger than the slow-climbing Nycticebus coucang.

The slow loris, Nycticebus coucang, ranges from Vietnam to Borneo, and the slender loris, Loris tardigradus, ranges from India to Sri Lanka.

These include Banded Leaf Monkey Presbytis femoralis, Sunda Slow Loris Nycticebus coucang, Malayan Porcupine Hystrix brachura.

In 1971, however, Colin Groves recognized the pygmy slow loris (N. pygmaeus) as a separate species, and divided N. coucang into four subspecies, including Nycticebus coucang menagensis.

The Sunda slow loris (Nycticebus coucang) or greater slow loris is a strepsirrhine primate and a species of slow loris native to Indonesia, western Malaysia, southern Thailand and Singapore.
