The black rhinoceros is also called the hook-lipped rhinoceros or Diceros bicornis. It is a critically endangered species native to eastern and southern Africa. Besides its large size and popularity, a black rhinoceros can exhibit diverse behavioral adaptations to survive even in the harshest environments.

The Physical Appearance of a Black Rhinoceros

Despite the reference to the black color, the black rhinoceros’s colors range from brown to grey. An adult rhino stands 132 to 180 cm (52 to 71 inches) tall at the shoulder and can grow to 2.8 to 3.75 m (9 to 12 feet) long.

They weigh about 800 to 1400 kg (1763 to 3086 pounds), with the cows (female rhinoceroses) slightly smaller than the bulls. The most striking feature of a black rhinoceros is the two horns on the skull made of keratin. In some cases, the species may have a third, smaller horn.

The Social Structure and Communication Methods of a Black Rhinoceros

Black rhinoceros mainly prefer to live alone, except for the females, who live with their calves or at occasional, temporary gatherings in water areas. This, in turn, reduces the competition for food and resources in the sparse habitats.

Male black rhinos are substantially territorial; they mark their spaces through scent from their dung and urine. They also rub their bodies against trees to leave their bodily scent to communicate their presence and dominance to other males.

Grunts, snorts, and trumpet sounds are the main ways through which black rhinos communicate. The tactics are employed differently, depending on the message they want to pass. For instance, warnings differ from mating calls, which are also different from distress signals.

What Do Black Rhinoceros Eat?

Black rhinos are browsers who feed on a range of bushes, shrubs, and trees. Their unique upper lip is specially adapted to hold and pluck out twigs and leaves. Feeding normally occurs during the cooler parts of the day to evade the heat.

Their ability to feed on different types of vegetation allows them to cope well in varying habitats. The species’ ability to conserve energy and stay hydrated in their mostly hot and arid environments.

The Social Interactions of Black Rhinoceros

The bond between a cow and its calf is unbreakable, with calves living with their mothers for as long as three years. A time in which the calf is taught essential skills for survival to ensure a successful transition into an independent life.

Black rhinos are infamous for their aggressive behavior, especially the males. They charge at perceived threats and intruders with strength and great speed. Fights between male rhinos often result in serious injuries. This aggression is part of their territorial trait and serves to guard their area and resources.

Black Rhinoceros Reproduction and Breeding

The courting period in black rhinos comprises a series of interactions, including chasing and vocal exchanges. Mating pairs can stay together for a couple of days during this period. This ensures that only the fittest individuals reproduce, guaranteeing robust health for the species.

Once the mating pair is mutually interested, they practice copulation, which is often prolonged; the pair stays together and mates multiple times. This increases the chances of successful fertilization. After mating, the bond between the pair is no longer there, and each goes their separate ways.

The gestation period for black rhinos is precisely 15 to 16 months; birthing a single calf – twins is rare but possible. The calf stays concealed from the public for its first few days before starting to follow its mother. This seclusion protects the defenseless newborns from predators.

Where Do Black Rhinoceros Live?

Black rhinos like to wallow in mud to regulate their body temperature, protect their skin from parasites, and prevent sunburn. Their skins are thick-layered, which comes in handy when going through thorns or sharp grass.

They inhabit various environments, from savannas and grasslands to forests and shrubs. You can find them in Eastern and Southern African countries, including Kenya, Tanzania, Eswatini, Mozambique, Malawi, Botswana, Angola, Zimbabwe, South Africa, Malawi, and Zambia. The average life expectancy of a black rhino is between 35 and 40 years.

How Do Black Rhinoceros Evade Predators?

Adult black rhinos have few predators because of their size, strength, and deadly horns. Calves, on the other hand, are more vulnerable and can fall prey to animals like lions, hyenas, and crocodiles. Mothers are highly protective of their offspring and aggressively defend their young, using their size and strength to scare away potential threats.

Despite having less helpful eyesight, rhinos have an exceptional sense of smell and hearing. These help in danger detection and navigation, compensating for their visual shortcomings.

Why Are Black Rhinoceros Endangered?

Unfortunately, black rhinos lie on the brink of extinction, a plight of many large mammals today. Factors like poaching, habitat loss, conflict with humans, and low reproductive rates contribute to the endangered status.

The dedicated efforts of conservationists, governments, and local communities offer hope that the black rhino’s future can be secured.

Conclusion

Contrary to their name, black rhinoceroses are not black but brown or grey. They majorly inhabit eastern and southern African countries, where they are huge tourist attractions. Male black rhinos prefer to live alone, with the majority of interactions being between cows and calves. The species feeds primarily on shrubs, leaves, trees, and bushes – they are strictly herbivores. Sadly, black rhinos are endangered. Conservationists, governments, and local communities are doing all they can to ensure this doesn’t happen.
