Rhinos are currently the second largest animals on land after elephants, with a body length of nearly 5 meters and a weight of up to 6 tons, but a height of no more than 2 meters and a life span of about 50 years.

Although rhinos are bulky, they can still walk or run at fairly fast speeds, even in dense, thorny forests. For example, African black rhinos can reach speeds of 45 kilometers per hour in short distances, so adult rhinos have no enemies except humans.

Like humans, rhinos have sensitive skin and can get sunburned. Although rhinos have thick skin, they are sensitive to sunburn and mosquito bites. That's why rhinos always like to roll in mud. When the mud dries, a protective layer forms to protect the rhino's skin from sunburn and mosquito bites.

Rhinos can only see things that are very close to it. Rhinos have very poor eyesight and are nearsighted. It won't find out until people or something is almost in front of it. So when rhinos see people or objects, they usually charge in self-defense.

Rhinos identify other rhinos by smell. Although rhinos have poor eyesight, they have a great sense of smell. Rhinos identify each other by taste, because each rhino's taste is unique!

Male rhinos have a strong sense of territory. In order to protect their territory, they are not afraid of lions, tigers, leopards and other creatures on the grasslands. To some extent, their androgen levels can be stimulated. Male rhinos that have been kept in captivity for a long time will lose their territorial awareness, and female rhinos will suffer from uterine problems that affect their reproductive ability and are eventually sterilized.

Rhinos have a very hard and sharp horn that is about 1 meter long. This is the most lethal weapon of rhinos. Only human hunting can hurt rhinos. Otherwise, basically in the African grasslands, rhinos have no natural enemies, and lions are no exception. Moreover, although the lion is a large cat, the size of the lion is far less than that of the rhino.

A single lion cannot beat a rhino, because the rhino weighs about 6 tons and has very hard skin. The rhinos that have been exposed to the wind and the sun all day are rough and thick, and their skin is covered with fine lines, which are hard and tough. The lion's teeth really can't do anything to them.
