The Javan Rhinoceros, Rhinoceros sondaicus is one of the rarest and most endangered large mammals anywhere in the world. According to 2002 estimates, only about 60 remain alive, in Indonesia and Vietnam. Even these tiny populations are still being poached and the outlook for the species is grim.

[edit] Habitat

Javan rhinoceri are primarily found in Ujung Kulon National Park. It is believed that there are still remnants of its population scattered in the rainforests of Laos, Kampuchea, and Southern Vietnam. These animals prefer large floodplains and mud wallows.

[edit] Physical features

Like the closely related larger Indian Rhinoceros, the Javan rhinoceros has only a single horn. Its hairless gray skin fall into folds into the shoulder, back, and rump giving it an armored-like appearance. The Javan rhino's body length reaches up to 10-10.5 feet(3.1-3.2 meters), including its head. Adults weigh up to 3,000-4,400 pounds(1,360-2,000 kilograms). Females are typically larger than the males and often have a knob instead of a horn. Like other rhinos, it has very poor eyesight, but an acute sense of smell.

[edit] Diet

The Javan Rhinoceros' diet include shoots, twigs, young foliage, and fallen fruit. It knocks down saplings to reach its food and grabs it with its prehensile upper lip.

[edit] Behavior & Reproduction

The Javan Rhinoceros is a solitary animal with the exception of breeding pairs and calves. They sometimes will come together at salt licks and mud wallows as well. The Females reach sexual maturity at 3-4 years of age while the males are at 6 years of age. The birth interval for this species is 4-5 years and the calve is weaned around 2 years.<ref>Javan Rhinoceros. Wildlife at Animal Corner. Animal Corner (2003). Retrieved on 11-11-06.</ref>

[edit] Conservation

The main reason for its decline are the low altitude rain forests due to logging which had a major impact on the population. Even with all the conservational efforts, the Javan rhinoceros' chance of survival is grim. Because most of the population is primarily kept in a small area, it is very prone to disease. By the 1930's the rhinoceros was nearly hunted to extinction in India, Burma, Malay, and Sumatra for the medical powers of its horn and blood.

[edit] Subspecies

There are three subspecies of the Javan rhinoceros.

Indian Javan Rhinoceros (Rhinoceros sondaicus inermis) (extinct)
Vietnamese Javan Rhinoceros (Rhinoceros sondaicus annamiticus) (Vietnam only 2 - 7 animals left)
Indonesian Javan Rhinoceros (Rhinoceros sondaicus sondaicus) (Java 50 - 60 animals left)
