Critically Endangered
Javan slow loris
Nycticebus javanicus
Javan slow loris is a loris in the family Lorisidae (order Primates) — Nycticebus javanicus, recorded as Critically Endangered and tied to Indonesia.
Appearance
The species has two forms, based on hair length and, to a lesser extent, coloration. Its forehead has a prominent white diamond pattern, that consists of a distinct stripe that runs over its head and forks towards the eyes and ears.
The Javan slow loris weighs between 565 and 687 g (1.25 and 1.51 lb) and has a head-body length of about 293 mm (11.5 in).
Range and habitat
The species is found only on the western and central portion of the island of Java in Indonesia. Its presence has been confirmed in the Dieng Mountains, and it is known to be found in low densities at Gunung Gede Pangrango National Park (in montane cloud forests) and Mount Halimun Salak National Park, often only where human disturbance is minimal. It inhabits both primary and secondary disturbed forest, and can be found from sea level to 1,600 m (5,200 ft), although it is more commonly found at higher elevations since lower elevations tend to be deforested.
The Javan slow loris is a strepsirrhine primate and a species of slow loris native to the western and central portions of the island of Java, in Indonesia.

Diet and breeding
Like other lorises, the Javan slow loris is nocturnal and arboreal, relying on vines and lianas. The Javan slow loris will eat fruit, lizards, eggs, and chocolate seeds.
It is also known to eat the gum of trees of the genus Albizia, in the legume family, Fabaceae, as well as from the palm genus Arenga (family Arecaceae). Instead of sleeping in nest holes, they sleep curled up on branches.
In crisis
The Javan slow loris population is in sharp decline because of poaching for the exotic pet trade, and sometimes for traditional medicine. Remaining populations have low densities, and habitat loss is a major threat. For these reasons, the International Union for Conservation of Nature (IUCN) lists its status as critically endangered, and it has also been included on the 2008–2010 list of "The World's 25 Most Endangered Primates".
Despite these protections, as well as its presence in several protected areas, poaching continues. The wildlife protection laws are rarely enforced at the local level. The Javan slow loris is listed by the International Union for Conservation of Nature (IUCN) as "critically endangered," primarily due to a rapid decline in population.
