What are Rhinoceros?

Rhinoceros are large, herbivorous mammals that are identified by their characteristic horn. There are five species of rhinoceros: the black rhinoceros, the white rhinoceros, the Indian rhinoceros, the Javan rhinoceros, and the Sumatran rhinoceros. Rhinos are found in Africa and Asia, and they play an important role in the ecosystems in which they live.

Rhinos are important in their ecosystems because they help to keep the vegetation in check. Without rhinos, the vegetation would grow out of control and eventually choke out other animals.

Rhinoceros Physical Appearance and Size


Rhinoceroses are large animals, and they vary in size depending on the species. The black rhino is the smallest of the species, and it can weigh up to 1,800 kg (4,000 lb). The white rhino is the largest and can weigh up to 2,300 kg (5,100 lbs).

The largest rhinoceros species now living is the white rhino, often known as the square-lipped rhinoceros. There are just two white rhinos in Ol Pejeta Conservancy in Kenya, yet they are constantly guarded. The last two female white rhinos could not reproduce after the last male’s death in 2018.

Rhinos have thick skin that is covered in hair. They also have a thick layer of fat that helps to keep them warm in cold climates. Additionally, the black rhinos have a thick, hairless gray hide. Both rhinos have two horns.

The Rhino horn is made of keratin, which is the same material that makes up human fingernails. In Africa, the southern white rhinos are the most common and are found in grasslands. The Woolly Rhinoceros had thick, shaggy hair covering them, unlike the modern rhinoceros we see now.

Although some of them also resided in grasslands, it was likely because they lived on ice. But they had protruding horns in front of their skulls, just like contemporary rhinos have.

Rhinoceros Habitat and Diet

Rhinoceros Habitat

Rhinoceros are found in Africa and Asia. The total black rhino population is found in eastern and southern Africa, while the white rhino is found in southern Africa. The Indian rhino is found in northern India and Nepal, and the Javan rhino is found in Indonesia. The Sumatraninoceros is found in Malaysia, Thailand, and Sumatra.

Rhinos are herbivores, and they eat a variety of plants. In Africa, the African rhino is the most common, and it is found in grasslands. Indian rhinoceros is found in forests, and the Sumatran rhino is found in rainforests.

Rhinos use their horns to dig up roots and bulbs, and they also use them to strip bark from trees. Rhinos are browsers, and they eat leaves, twigs, and fruit. The animal’s neck and temporalis muscles being larger is another piece of supporting organ. Did they consume food alone? The Woolly Rhinoceros most likely ate a diet similar to that of current rhinos. They could eat alone, in a group, or as a family.

They resemble modern rhinos in many ways. Regarding their food, there are various issues. Investigations showed that they might have been grazing and browsing simultaneously. While browsing refers to eating leaves and woody twigs from trees and bushes, grazing refers to consuming grass and other low-lying vegetation.

It is thought that trees, moss, grasses, and bushes were the woolly rhinoceros’ preferred habitats. A number of pieces of evidence supported these presumptions. The fact that the woolly rhinoceros preferred to graze over browse, however, was more pervasive in this evidence.

The skull, mandible, and teeth of a Woolly Rhinoceros from Staffordshire were subjected to biochemical analysis, which revealed the musculature and dental traits of a grazing animal. They reproduce slowly, and they have a gestation period of 16 months. Calves are born weighing between 40 and 65 kg (88-143 lb).

Rhinoceros Behavior

Rhinoceros Behavior

Rhinos are generally peaceful animals, but they can be aggressive if they feel threatened. Rhinos are also known to attack humans if they feel any threat or if they are provoked.

They are social animals, and they live in herds of up to 30 individuals. The size of the herd depends on the species of rhino. Rhinos communicate with each other through vocalizations and body language. Rhinos use their sense of smell to find food and to communicate with each other.

The black rhino (Diceros bicornis) can charge at any strange sound or smell because it is typically unpredictable and moody. Despite their size, rhinoceroses are incredibly agile. The black rhino, for example, can circle back quickly after missing a charge and may reach speeds of up to 45 km/h (30 mph) even in dense undergrowth.

The three Asian species battle not with horns but with their razor-sharp lower outer incisor teeth. When used by dominant male Indian rhinoceroses, these teeth, or tusks, can grow to a length of 13 cm (5 inches) and cause fatal wounds to rival males vying for the attention of breeding females. African species, in contrast, lack these long incisors that resemble tusks and instead use their horns for combat.

Do You Know?

  • Rhinoceros horns are used for defense, and they will charge at predators if they feel threatened.
  • Rhinoceros are social animals, and they live in herds of up to 30 individuals.
  • Rhinos use their sense of smell to find food and to communicate with each other.

Rhinoceros Threats and Predators

Rhinoceros Predators

Humans hunt rhinos for their horns, which are used for medicinal purposes. Rhinos are also poached for their meat and skin, which are used to make leather products. Rhinos are killed for their horns, which are made of keratin. Rhino horn is used in Chinese traditional medicine, and they are also used to make dagger handles in Yemen.

Rhino populations have declined dramatically in recent years due to rhino poaching and habitat loss. It is estimated that there are only 5,000 left in the wild. The Indian rhinoceros is also critically endangered, with a calculated figure of 3,500 remaining in the wild.

Rhinos are protected by law, but this has not stopped poachers from hunting them. So to protect rhinos and to stop the illegal rhino horn trade, there is a need to make rhino protection units in the national park and at governmental levels. This way, it will become more convenient to increase and protect the rhino population.

Rhinoceros Discoveries and Fossils

The first recorded rhinoceros was killed by Julius Caesar in 46 BC. Rhinoceros fossils have been found in Africa, Asia, and Europe. The oldest known rhinoceros fossil is from Africa, and it is calculated to be 24 million years old. The name “rhinoceros” comes from the Greek words “rhino”, meaning nose, and “Keras”, meaning horn.

The Woolly Rhinoceros is represented by a variety of fossils. This is because, like the Woolly Mammoth, the rhino was almost completely intact when it was discovered in permafrost. Sasha is the most well-known of these fossils. A hunter in Siberia came across Sasha, a young woolly rhinoceros.

Sasha is a five-foot-long corpse with scruffy hair that has been meticulously kept. Because Sasha is so complete, researchers are attempting to obtain a DNA sample from it. In the event that they are successful, they might mix this with the genome of the Sumatran rhinos to successfully reproduce a woolly rhinoceros.

The Woolly Rhinoceros, however, first appeared in fossil form some 350,000 years prior to this finding. The fossils were discovered throughout Asia and Europe, either in ice or oil-saturated soil. The woolly rhinoceros apparently never made it to North America. They discovered the entire carcass of a female rhino in Ukraine. Only the hair and the hooves were missing.

The rhinoceros is a member of the family Rhinocerotidae, which includes the five extant species of rhinoceros. The Rhinocerotidae family also includes the extinct woolly rhinoceros. The rhinoceros is an ancient animal, and it has been around for millions of years.



Rhinos have existed for millions of years, and humans are the only serious threat to them. In addition to benefiting other species, environments, and societies merely by existing, rhinos are compassionate animals that do not hurt humans. Because of the natural resources that provide food, fuel, and money inside the rhino habitat, humans benefit from having rhinos.

The main objective is to stop poaching in order to save rhinos from extinction. Paramilitary training methods, night vision helicopter monitoring, electronic tracking technology, and intelligence collection are all used as poaching prevention strategies.
