Rhinocero

The rhinos are excellent swimmer, getting to spend several hours in the water can ease the bite of insects. Its horn, different than we think, is not made of bone, but made of hair extremely compact forming a structure very sturdy. Their skin can have up to 7 cm and despite the size and weight, which vary according to each species, can reach up to 80 km \ h.
The rhino can sometimes be seen with another species, the Tchiluanda. The Tchiluanda is an African bird that picks ticks and tells the rhino nearby enemies.
There are 5 species of rhinos in the world: Indian rhinoceros, Rhinoceros White (second largest land mammal), Java Rhino, Black Rhinoceros, Sumatran Rhinoceros.

The rhino has adult predators are only the man. The young can fall victim to lions, tigers and hyenas if there is a favorable opportunity for them. All species of rhinos are endangered because they are very low fertility (each female has only one litter every two years). So very vulnerable to hunters, in addition to suffering the destruction of their habitat.
They have been hunted extensively because nearly all its parts are used in traditional Asian medicine. The most valuable is the horn that has been used as an aphrodisiac, to cure fevers, for cables of daggers in Yemen and Oman, or to prepare a potion that is supposed to detect poison.
