Interesting & Amazing Information On Javan Rhino
- Javan Rhino is an herbivore and one of the three rhino species found in Asia. Once, this rhino species was very common in Indo-china and was often spotted in grasslands and flood plain. However, it now resides in the dense tropical rain forest of Ujung Kulon National Park, in Indonesia.
- Javan rhino is smaller in size than its Indian cousin and bears close resemblance with the Black Rhinoceros, in so far as its size is concerned. The body of this rhino (including head) can extend up to 3.1 to 3.2 m (10 to 10.5 feet), and it can have a maximum height of 1.4 to 1.7 m (4.6 to 5.8 ft).
- The male Javans mark their territory with dung piles and by spraying their urine. For the purpose of communicating territorial limits, they also use scrapes made by the feet, in the ground and twisted saplings.
- These rhinos have a skin with natural mosaic pattern, which gives them an armored appearance. They have a hairless body, with gray or gray-brown skin falling in folds to the shoulder. Fecale samplings and camera traps have determined these physical details about the Javan rino, to avoid the risk of directly interfering with a critically endangered species like theirs.
- Javan rhinos are less vocal than the other rhinos, which is why very few vocalizations of these rhinos have been recorded.
- It is believed that there are less than 100 Javan rhinos left in the wild. Although their number is less than that of the endangered Sumatran rhinos, they have a more protected habitat range.
- Javan rhino mostly leads a solitary life, except for courtship and child rearing. However, groups of these rhinos may assemble near wallows and salt licks.
- These rhinos do not predate on animals or humans. They usually avoid contact with humans, but can attack on feeling threatened.
- Due to their extreme rarity, scientists and environmentalists have not conducted many studies on the endangered Javan rhinos. As a result of this, Javan is the least studied of all the existing rhino species.
