Rhinoceroses

Rhinoceros is one of the most endangered animal The word

"rhinoceros" is derived from the Greek words rhinos, meaning nose, and keras, meaning horn

the rhino is prized for its horn The horns of a rhinoceros are made of keratin, the same type of protein that makes up hair and fingernails

.Both African species and the Sumatran Rhinoceros have two horns, while the Indian and Javan Rhinoceros have a single horn Rhinoceri have acute hearing and sense of smell, but poor eyesight Most live to be about 60 years old or more

2 species(black and white) can be found in Afica and 3 species (javan, Indian and Sumantran) inAsia

1) Black rhinoceros

He name Black Rhinoceros (Diceros bicornis) was chosen to distinguish this species from the White Rhinoceros (Ceratotherium simum) This can be confusing, as those two species are not really distinguishable by colour

An adult weighs from 800 to 1400 kg exceptionally to 1820 kg (4,000 lb), with the females being smaller than the males

Two horns on the skull are made of keratin with the larger front horn typically 50 cm long, exceptionally up to 140 cm Sometimes, a third smaller horn may develop

Two horns on the skull are made of keratin with the larger front horn

typically 50 cm long, exceptionally up to 140 cm Sometimes, a third

smaller horn may develop The Black Rhino is much smaller than the

White Rhino, and has a pointed mouth, which they use to grasp

leaves and twigs when feeding

2) White rhinoceros

The white rhinoceros is acyually gray It can be found in Africa The white in this speci;s name is from the Afrikaan word “wyd”,which means “wide” It is the biggist rhino

of 5 species

The White Rhino has an immense body and large head, a short neck and broad chest This rhino can exceed 3000 kg

The record-sized White Rhinoceros was about 4500 kg

On its snout it has two horns The front horn is larger than the other horn and averages 89.9 cm in length and can reach 150 cm

The Indian Rhinoceros has thick, silver-brown skin which creates huge folds all over its body

Fully-grown males are larger than females in the wild, weighing from 2200–3000 kg ( Female Indian rhinos weigh about 1600 kg The record-sized specimen of this rhino was approximately 3500 kg

The Indian Rhino has a single horn that reaches a length of between

20 and 101 cm Its size is comparable to that of the White Rhino in Africa

The Indian Rhinoceros or the Great One-horned Rhinoceros (Rhinoceros

unicornis) is found in Nepal and in Assam, India The rhino once inhabited many areas of Pakistan to Burma and may have even roamed in China But because of human influence their range has shrunk and now they only exist in small populations in north-eastern India , Nepal and in a national park in Pakistan

3) Indian rhinoceros

The Javan Rhinoceros is one of the rarest and most endangered large mammals anywhere in the world

According to 2002 estimates, only about 60 remain, in Java (Indonesia) and Vietnam

By the 1930s the rhinoceros was nearly hunted to extinction in India, Burma, Peninsular Malaysia, and Sumatra for the supposed medical powers of its horn and blood

Like the closely related larger Indian Rhinoceros, the Javan rhinoceros has only a single horn

Adults are variously reported to weigh between 900–1,400 kg or 1,360-2,000

kg Males horns can reach 26 cm in length while in females they are knobs

or no horn at al

4) Javan rhinoceros

5) Sumatran rhinoceros

The Sumatran Rhinoceros is the smallest extant rhinoceros species

Due to habitat loss and poaching, its numbers have declined and it is one of the world's rarest mammals About 275 Sumatran Rhinos are believed to

remain

A mature Sumatran rhino stands about

130 cm high at the shoulder, a body length of 240–315 cm and weighs around 700 kg

Like the African species, it has two horns; the largest is the front (25–79 cm) and the smaller being the second, which is usually less than 10 cm long The males have much larger horns than the females

They are called “magic medical” The value of rhino’s horn makes it enormously profitable So people poach and sell them to serve their purpose

Rhino’s horns are very useful because they might help care everything

6) Rhinoceros’s horn

-People Should keep the natural habitet
