Rhinoceri

Rhinoceri are mammals just like humans. They are herbivors which means they only eat vegation and not meat.

RhinoceriBy, Milton Newman

Where did they get their name?Rhinoceri got their name from the greek root "rhino" meaning nose and "ceros" meaning horn.

Rhinoceri have been hunted almost to extinction because it is said their horns have "healing properties". Save the Rhino estimated that about 500,000 rhino's lived in the wild in Africa at the start of the 20th century. Now they say there is about 29,000 living in the wild.

Rhino horns are made of keratin, which also makes up human fingernails and hair. CT scans have shown dense mineral deposits of calcium and melanin in the core of the horn. The calcium makes the horn stronger, and the melanin protects it from the sun's UV rays.

Their Horn

How Many There Are.

On the black rhino, the front horn can grow to 20 to 51 inches (51 to 130 centimeters), while the rear horn can grow to about 20 inches, according to the International Rhino Foundation. A white rhino's horns are slightly smaller, and a Sumatran rhinos horns are about 10 to 31 inches (25 to 79 cm). The greater one-horned rhino's horn is 8 to 24 inches (20 to 61 cm), and Javan rhinos have a horn that is about 10 inches (25 cm) long.

How big are rhinos?The largest rhino species is the white rhino, according to the San Diego Zoo. It grows from 12 to 13 feet (3.7 to 4 meters) long and up to 6 feet (1.8 m) from hoof to shoulder. It weighs around 5,000 lbs. (2,300 kilograms).The smallest rhino species is the Sumatran rhino. It grows from 8 to 10 feet (2.5 to 3 m) long and up to 4.8 feet (1.5 m) from hoof to shoulder. The Sumatran rhino weighs around 1,765 lbs. (800 kg).

White rhinos and black rhinos live in the grasslands and floodplains of eastern and southern Africa. Greater one-horned rhinos can be found in the swamps and rain forests of northern India and southern Nepal. Sumatran and Javan rhinos are found only in small areas of Malaysian and Indonesian swamps and rain forests.

When rhinos are happy, they make a loud "mmwonk" sound with their mouths.The woolly rhino died out about 10,000 years ago. Fossils have been discovered throughout Europe and AsiaThough rhinos don't often hang out with each other, they do hang out with birds. The oxpecker will sit on a rhino's back and eat the bugs that crawl on the rhino's skin. That's not the only thing this bird is good for. When danger approaches, the bird will call out, warning the rhino.
