The rhinoceros is the second largest land animal after the elephant. Its body length is 5 m, its height is 1-2 m, and its weight is 2-4 tons. Rhinos have thick skin, and there are 1-2 horns on the head. Sometimes there can be 3-5 horns (in a black rhinoceros). The structure of the horn resembles a hoof (or our nails), that is, it is a skin formation. Its length can exceed 1.5 m.
The life span of rhinos is 50-60 years.
Rhinos keep one by one or in pairs (female and calf). The female gives birth to one cub (very rarely twice) every 2-3 years after 17-19 months of gestation. The cub stays with the mother until the next offspring is born.
Rhinos are predominantly nocturnal and feed only on plants. In search of food, animals can travel long distances.
These animals have very well developed hearing and smell, but they see poorly. Therefore, in order to navigate the terrain well and not accidentally run into someone else's territory, rhinos leave odorous marks (manure) on the borders of their possessions.
On the limbs of the rhinoceros there are three fingers, each of which has a hoof.
Now there are 5 species of rhino left on Earth: Indian, Javanese and Sumatran - in Asia, black and white - in Africa. All rhino species are endangered and listed in the Red Book.
In Asian rhinos, the skin forms deep folds, so it seems as if the animal is dressed in a shell consisting of separate plates.
African rhinos often carry buffalo starlings on their backs, which remove ticks and other blood-sucking insects from the skin of animals.
In speed, the black African rhinoceros rhino is not inferior to a horse and can reach speeds of up to 40 km / h.
