Javan rhinoceros is one of the rarest large mammals, now surviving in a tiny Indonesian range. Because the range is so restricted, disease, tsunami, or volcanic disturbance could have severe effects.

It uses lowland tropical forest, wetlands, and dense riverside vegetation. Main habitat types in this guide are forest, freshwater.
Typical length 300-320 cm, weight 900 kg-2.3 t. It has a single small horn, heavy folded skin, and a massive body, slightly smaller than the Indian rhinoceros.
It is active in repeated bouts across day and night and usually solitary. Adults are solitary and repeatedly use wallows and forest trails.
It is herbivorous. Leaves, shoots, fruit, and shrubs are browsed inside forest habitats.
Females bear single calves at long intervals, and calves remain with the mother for a long period.
Wild populations are extremely limited and require strict protection. Because the range is so restricted, disease, tsunami, or volcanic disturbance could have severe effects.
