SUNDA RHINOCEROS (Rhinoceros sondaicus)


SUNDA RHINOCEROS(Rhinoceros sondaicus
created by : Muhammad Fathan Hidayat



The Sunda rhinoceros (Rhinoceros sondaicus), also known as the Sunda rhinoceros or lesser one-horned rhinoceros, is a very rare member of the family Rhinocerotidae and one of five extant rhinoceroses. It belongs to the same genus as the Indian rhinoceros, and has similar mosaicked, armour-like skin, but at 3.1–3.2 m (10–10 ft) in length and 1.4–1.7 m (4.6–5.6 ft) in height, it is smaller (closer in size to the black rhinoceros of the genus Diceros). Its horn is usually shorter than 25 cm (9.8 in), and is smaller than those of the other rhino species. Only adult males have horns; females lack them altogether.
Once the most widespread of Asian rhinoceroses, the Sunda rhinoceros ranged from the islands of Java and Sumatra, throughout Southeast Asia, and into India and China. The species is critically endangered, with only one known population in the wild, and no individuals in captivity. It is possibly the rarest large mammal on Earth,[5]:21 with a population of as few as 58 to 61 in Ujung Kulon National Park at the western tip of Java in Indonesia.

Life Cycle
A rhino calf is born after a gestation period of roughly 475 days, or about 16 months. However, the mother may be pregnant with her calf for as long as 18 months. Only one calf is born per pregnancy, and arrives in the world covered in red-brown hair. This hair protects the calf from the elements, keeping it warm at night and preventing sunburn during the day.
When the calf is about two years old (for males) to four years old (for females), it will break away from its mother to pursue its own solitary, independent life. This gives the mother the opportunity, after several years with her calf, to look for a mate and bear another young rhino, which she will not do whilst still caring for an older calf. Since both males and females need to establish their own territory once they leave their mothers, it is important that they are strong enough to do so for themselves. For this reason, female calves will stay under the protection of their mothers for longer, while males tend to get stronger and bigger quicker.

To establish its own territory is no mean feat for a rhinoceros. It will be chased from many areas by other rhinos that have already claimed these territories as their own. It will need to be able to hold its own in a battle with one of these, or know when to run.
The female rhino will be ready to begin mating at around four years of age, while males tend to start looking for a mate at about seven years old. After mating, the male and female rhino will part ways and not have much more to do with one another. The male will continue to mate with as many females as possible, but will not be involved in the rearing of any of his young.


After a life of roaming the plains, copulating and, in the case of a female, rearing the young, the rhino will eventually die. Sadly, not many rhinoceroses reach an age that allows them the dignity of dying of natural causes. Rather, they are being savagely hunted and slaughtered for their horns, which are believed to have medicinal powers, and are also sold for their sheer ornamental appeal. It is essential that effective, legal measures be put into place and enforced to prevent the total annihilation of this magnificent animal.

The Uniqueness
1.Used Scattered Regional Area

The scientific name of Javan Rhinoceros is Rhinoceros sondaicus; from the Greek "rhino", meaning "nose" and "ceros" meaning "horn". Sondaicus is derived from the word "Sunda," the western part of Java. Also indicates a series of large Sunda islands covering the Indonesian archipelago in the western part of Sumatra, Kalimantan, Java to the Lesser Sunda Islands namely Nusa Tenggara.
In the past, Javan rhinoceros is believed to spread in Southeast Asia, Sumatra to Java. The last individual outside the TNUK in Java was shot dead by a hunter in Tasikmalaya in 1934. Currently the specimen can be seen at the Bogor Zoological Museum. This is the only complete specimen Javan rhinoceros that can be seen by visitors.
2.Skin and Myth Around Rhino Rhinoceros

Javan rhinoceros skin has a kind of crease that looks like wearing a steel shield. Has an appearance similar to the Indian rhinoceros but the body and head are smaller with fewer folds. The upper lip is more prominent so it can be used to reach food and put it in the mouth. Rhinos include shy and solitary types (loners).
Javan rhino has one horn (another species has two horns). Its horn is the smallest horn of all rhinoceros, its length between 20 cm to 27 cm. Javan rhino rarely uses his horn to fight, but uses it to move the mud in the puddles, or to pull the plants in order to be eaten and open the stub through the thick vegetation.
There is nothing to do between the rhinoceros horn with the powerful myths of medicine. Rhinoceros horn is made of hardened keratin material, identical with horn or buffalo or cow's nails.
3.Proliferation Slow

Since the last few years the rhino census in Ujung Kulon shows a steady amount. Some camera trap results show the rhinoceros who was caught on camera with the parent. However, the reproductive rate of Javan Rhino is relatively slow; females give birth to one in 4-5 years intervals, after 15 to 16 months of gestation. Moreover, Javan rhinoceros is a species that spends most of its time by being alone. The average age of this rhino is between 40 years to 45 years.
The results of monitoring the Java rhino in 2013 in Ujung Kulon National Park (TNUK) through recording surveillance camera estimated the population of 58 individuals.
4.Rhino is a Herbivor

The adult Javan Rhinoceros weighs 900 - 2300 kg, and is estimated to eat 50 kg of food per day! Javan Rhinoceros are herbivorous animals and eat a variety of plant species, especially buds, twigs, young leaves and fallen fruits. Most plants favored by this species grow in sun-exposed areas. The biggest problem in Ujung Kulon, some rhino feed is similar to bull (Bos javanicus) which causes them to compete for food.
Another problem is the invasive invasive palm spreading (Arenga obtusifolia) a type of aren that rapidly proliferates in swamp forests and lowlands through seeds propagated by civets. Langkap has replaced the vegetation which is a rhino feed. It is estimated that Langkap has invaded 30 percent of the Ujung Kulon peninsula. Until now there is no effective way to prevent the development of duplicate.
