The Javan slow loris (Nycticebus javanicus) is a small, furry primate. It lives only on the island of Java in Indonesia. This special animal is a type of slow loris. For many years, scientists thought it was a subspecies of another loris. But new studies showed it is its own unique species. It is closely related to the Sunda slow loris and the Bengal slow loris.
This loris has a clear white diamond pattern on its forehead. A stripe runs over its head and splits towards its eyes and ears. The Javan slow loris weighs about 565 to 687 grams. It is about 293 millimeters long from head to body. Like all lorises, it lives in trees. It moves slowly and carefully across vines and branches. It does not jump between trees. Its home includes different kinds of forests. You can find it in bamboo forests, mangrove forests, and even chocolate farms. It eats fruits, tree sap (called gum), lizards, and eggs. It usually sleeps on open branches, sometimes with other lorises. It is often seen alone or in pairs.
Sadly, the Javan slow loris population is shrinking fast. This is mainly because of poaching. People illegally catch them to sell as exotic pets. Sometimes they are used in traditional medicine because of old beliefs. There are not many left, and their homes are disappearing. Because of these threats, the International Union for Conservation of Nature (IUCN) says it is a critically endangered species. This means it is at very high risk of disappearing forever. It is protected by Indonesian law. It is also listed under CITES Appendix I, which helps control international trade. Even with these rules, poaching continues. Local laws are often not strongly enforced.

The Javan Slow Loris: A Unique Primate
Discovery and Scientific Journey
The Javan slow loris was first described by scientists in 1812. A French naturalist named Étienne Geoffroy Saint-Hilaire gave it the name Nycticebus javanicus. The name "javanicus" tells us it comes from Java. For a long time, scientists thought it was just a type of the Sunda slow loris.
In the 2000s, scientists looked at its body features and DNA sequences. They found that it was different enough to be its own species. This means it is a unique kind of slow loris. It is most closely related to the Bengal slow loris and the Sunda slow loris. Sometimes, even animal rescue centers have trouble telling it apart from other lorises. This shows how similar they can look!
There are two slightly different forms of the Javan slow loris. They mainly differ in how long their fur is. Scientists are still studying if these forms are distinct or just variations within the same species.
Physical Appearance and Features
The Javan slow loris weighs between 565 and 687 grams. This is about the same as a small pineapple. It looks similar to the larger Bengal slow loris. Its face and back have a clear stripe. This stripe goes over its head and splits towards its eyes and ears. This creates a white diamond shape on its forehead. Its fur is yellowish-gray. But its head, neck, and shoulders have creamy white colors.
Like some other slow lorises, it has a special feature in its mouth. It is missing one of its front teeth (the second incisor). The Javan slow loris is bigger than the other slow lorises found in Indonesia. These are the Sunda slow loris and the Bornean slow loris.
Some Javan slow lorises have longer fur than others. Their fur can be about 26.8 millimeters long. Others have shorter fur, around 22.4 millimeters. The longer-furred ones are often lighter brown. The shorter-furred ones can be more reddish-brown.
Life in the Trees: Behavior and Diet
Like all lorises, the Javan slow loris is nocturnal. This means it is active at night. It lives in trees, moving slowly using vines and branches. It can sometimes move on the ground if it needs to cross open areas. It usually stays high in the trees, between 3 and 22 meters up. But it is often seen between 1.5 and 9.5 meters high.
What the Javan Slow Loris Eats
The Javan slow loris eats many different things. Its diet includes fruits, lizards, and eggs. It also enjoys chocolate seeds. It likes to eat the sticky sap, called gum, from trees. These trees include Albizia and Arenga palms.
Daily Routines and Habits
Javan slow lorises are usually seen alone or in pairs. Sometimes, they sleep in groups. They do not build nests. Instead, they curl up on branches to sleep during the day. Like other slow lorises, they make a special sound. It sounds like a high-pitched whistle. This species can also host a tiny parasitic flatworm called Phaneropsolus oviforme.
Where the Javan Slow Loris Calls Home
This special loris lives only in the western and central parts of Java, Indonesia. Scientists have found it in places like the Dieng Mountains. It also lives in Gunung Gede Pangrango National Park and Mount Halimun Salak National Park. It prefers areas where people do not disturb it much.
It lives in both untouched forests and forests that have been changed by humans. You can find it from sea level up to 1600 meters high. It is more common in higher places. Lower areas often have fewer trees. Studies show it can live in bamboo forests, mangrove forests, and even on farms. It especially likes chocolate plantations. In 2008, they were seen living in mixed-crop gardens in West Java. This shows they can live even near people.
Protecting This Endangered Species
The International Union for Conservation of Nature (IUCN) lists the Javan slow loris as "critically endangered." This is because its population has dropped very quickly. In the last 21 to 24 years, its numbers have gone down by at least half. There are not many of them left. Studies show only about 0.02 to 0.20 lorises per square kilometer.
Why the Javan Slow Loris Needs Help
Its numbers are still going down. The main reason is poaching. People illegally catch them. In Indonesia, some people use them in traditional medicine. They believe the lorises have special healing powers. But most often, they are sold as exotic pets. It is easy to catch them because they move slowly. They are also active at night and sleep on open branches. Poachers actively look for them. They also catch them when forests are cut down.
Their homes are also disappearing. Most of this habitat loss happened before the mid-1980s. But human activity is still very strong in their living areas. Scientists believe the Javan slow loris is more threatened by habitat loss than other slow loris species. Because of these serious threats, it is on "The World's 25 Most Endangered Primates" list. This list is made by important conservation groups.
Global and Local Conservation Efforts
Since June 2007, the Javan slow loris has been on CITES Appendix I. This gives it strong protection against international trade. It is also protected by Indonesian law. However, researchers say that these laws are not always enforced well in Indonesia.
The species lives in several protected areas. But we do not know exactly how many are there. Some Javan slow lorises live in zoos. You can find them in Prague, Czech Republic, Jakarta, Indonesia, and Singapore. These zoos help protect the species.
A group called the Little Fireface Project is working on Java. They have built special walkways high in the trees. These help the lorises move safely between treetops. This is important in areas where farms have replaced forests. These walkways also help local farmers by carrying water. In return, the farmers help take care of the walkways. This is a great way to help both people and animals!
