Sumatran Rhino


The Biggest Animals Kingdom and in The World | Sumatran Rhino | A mature Sumatran rhino is about 120-145 cm (3.9 to 4.76 m) high at the shoulder, a body length of about 250 cm (8.2 ft) and a weight of 500 800 kg (1,100 to 1,800 lb), although larger individuals in zoos have been known to weigh up to 1000 kg (2200 lb). Like the African species, has two horns. The larger nasal horn is also known as the anterior horn, posterior horn of the smallest in the frontal horn. Males have larger horns than females, although the species is nothing sexual dimorphism. The rhino has a small fold of skin around the neck. The skin is very thin, 10-16 mm (0.39 to 0.63), and wild rhinos seems to have no subcutaneous fat. In nature, these hairs are difficult to observe because the rhinos are often covered in mud.

The rhino is a long piece of hair around the ears and a thick tuft of hair at the tip of the tail. Like all rhinos, they are very poor. The Sumatran rhino is fast and agile, climbs mountains easily and comfortably traverses steep slopes and rivers. The Sumatran rhino is life on the plains and plateau secondary forests, swamps and rainforests. The Sumatran rhino once inhabited a continuous range to northern Burma, eastern India and Bangladesh. All known living animals occur in Peninsular Malaysia, Sumatra and Sabah, Borneo. Some environmentalists hope Sumatran rhino can still survive in Burma, but is considered unlikely.

The Sumatran rhino is widely spread throughout the area, much more than other Asian rhinos, making it difficult for conservationists to protect members of the species effectively. Only six areas known to contain the community of more than a handful of Sumatran rhinos in Bukit Barisan Selatan National Park Gunung Leuser National Park and Kambas National Park, Sumatra, Taman Negara National Park in Peninsular Malaysia and Tabin Wildlife Reserve Sabah, Malaysia on the island of Borneo. Kerinci Seblat National Park, the largest of Sumatra, was estimated at a population of about 500 rhinos in 1980, but because of poaching, the population is considered extinct.

Genetic analysis of the Sumatran rhino population has identified three distinct genetic lineages. The channel between Sumatra and Malaysia was not a significant barrier for the rhinos as the Barisan Mountains along the Sumatran rhinos in eastern Sumatra and Peninsular Malaysia are more related than the rhinos on the other side of the mountains West Sumatra. The rhinos of Borneo are sufficiently distinct to conservation geneticists have advised against crossing lines with other populations. The initial test results showed that the levels of variability within Sumatran rhino populations comparable to the population of endangered African rhinoceros lower, but the genetic diversity of Sumatran rhino is an area of ongoing study are Sumatran rhino solitary creatures except for the association for mating and during child rearing.

Fields of females appear to be spaced intervals males often overlap. No evidence of Sumatran rhinos defend their territory by fighting. The Sumatran rhino is usually activated when eating little at dawn and after sunset. During the day the rhino wallows in mud baths to cool off and relax. The rhino spends most of his days wallowing. When there is no mud holes, the rhino will deepen puddles with its feet and horns. Wallowing behavior helps the rhino maintain its body temperature and protect the skin from ectoparasites and other insects. Specimens in captivity, without adequate wallowing, have quickly developed skin abscesses and inflamed chapped, eye problems, inflamed nails, hair loss and eventually die. After two to 12 weeks with a particular wallow, the rhino will abandon. 

Although in zoos the Sumatran Rhino has been observed wallowing less than 45 minutes a day, the study of wild animals 80-300 minutes (median 166 minutes) per day spent in wallows. There have been few opportunities to study the epidemiology of the Sumatran rhino. The Sumatran rhino has no known predators other than humans. The elephants (Elephas maximus) and Sumatran rhino is also known that the course of action, and many smaller species such as deer, wild boar and wild dogs use routes rhinos and elephants create The Sumatran rhino maintains trails across its range. In the areas of food, rhinos making roads, always vegetated areas containing food the rhino eats. Roads Sumatran rhino found that the bottom of the rivers of more than 1.5 meters (5 feet) and 50 meters (165 feet) in diameter. The relative absence of wallows near rivers to order Sumatran Rhinoceros indicates that sometimes can take a bath in the river, instead of wallowing

The Sumatran rhino is the most vocal rhino species. The rhino makes three distinct sounds: AEA, whales and sneaks shots. The strong whistleblowing vocalizations, loud enough for the iron bars in the zoo enclosure where the rhinos were studied vibrate. Hit The complaint is heard at a great distance, even in dense shrubbery where Sumatran rhino lives. The Sumatran rhino is sometimes twist saplings, do not eat. The reproductive habits of the Sumatran rhino in captivity have been studied. The court model is very similar to the black rhino. Young male Sumatran rhino are often too aggressive with women, sometimes injuring and killing during courtship. Cincinnati Zoo Rhinos were observed copulating for 30-50 minutes, in a manner similar to the duration of rhino conservation rhino other observations Sumatra center in Malaysia has shown a series of brief intercourse. The Cincinnati Zoo has had successful pregnancies, and other rhinos have also long periods of coupling along a road can be a natural behavior. Reproductive success was finally achieved in 2001, 2004 and 2007, providing additional progestin pregnant rhino.
