The white rhinoceros is one of the most easily identifiable animals in Africa, thanks to its square lip. It is the largest of all the five species of rhinoceros and can weigh up to 2,000 kg! The white rhino is a herbivore and spends most of its time grazing on grasses. In this blog post, we will learn more about these impressive animals!

The white rhino is one of the largest African animals, coming in after only the elephant and hippo. They usually weigh around 1,700 to 2,400 kg.
Contrary to popular belief, white rhinos are not actually white. Their grey color is a result of a misinterpretation of the Dutch word ‘wijde’ (wide) to describe the shape of the rhino's mouth.
The white rhino has a wider mouth to allow it to graze on grass, while the narrower black rhino's mouth is adapted for eating leaves, shoots, and branches.
Rhino horn has a long cultural history of being used in traditional Asian medicines, as well as to flaunt one's social status.
The white rhino is a grazer and spends most of its time eating grass. They can consume up to 80 kg of food per day! Due to their size, they need to spend around 16 hours a day feeding.
Because they are constantly grazing, white rhinos play an important role in the African ecosystem by keeping the grass short. This benefits other animals who eat grass, as well as the health of the Savannah.
It is thought that their grazing also helps to spread seeds and fertilize the soil with their dung.
Mating season for white rhinos is usually between June and August. During this time, the males will become increasingly aggressive as they compete for females.
The gestation period for a white rhino is 16 months and they will usually only have one calf at a time.
However, twins have been known to occur on occasion.
When the calf is born, it weighs around 50-60 kg and is almost fully grown. The mother will protect her calf for the first few years of its life.
The average lifespan of a white rhino in the wild is around 35 years but they can live for up to 50 years in captivity.
Habitat and Distribution
White rhinos are found in the Savannah grasslands of Africa. They used to have a much wider range but due to hunting and habitat loss, they are now restricted to only a few countries in East and Central Africa.
The majority of the white rhino population is found in South Africa with smaller populations in Kenya, Uganda, Tanzania, Zimbabwe, and Namibia.
White rhinos are semi-aquatic and love wallowing in mud to cool down and protect their skin from the sun. They are also good swimmers!
They are most active during the cooler hours of the day and will often spend over half of the day sleeping or resting.
White rhinos are social animals and live in groups of up to 14 individuals, led by a dominant male. However, groups of females and their calves are the most commonly seen.
The size of the group depends on the availability of food and water, as well as the presence of other rhino groups in the area.
White rhinos are generally peaceful animals but can become aggressive if they feel threatened. When two males meet, they will often fight for dominance.

The white rhino is classified as a near-threatened species by the IUCN. Although their numbers have increased in recent years, they are still at risk of extinction.
The biggest threat to the white rhino is poaching. Their horns are valuable on the black market and are used for traditional Asian medicines and ornamental purposes.
A single horn can be worth up to $300,000!
The white rhino is also at risk from habitat loss and conflict with humans. As the human population in Africa continues to grow, there is less space for wildlife. This leads to increased contact between humans and animals, which can often result in conflict.
Climate change is also a threat to the white rhino as it is predicted to cause more extreme weather conditions and reduce the amount of available food.
The white rhino is protected by law in many countries and there are several conservation projects underway to help protect this species.
One of the most successful projects is the Rhino Repatriation and Conservation Project in Kenya. This project aims to move white rhinos from zoos back into the wild.
So far, this project has released 10 rhinos into Kenyan national parks and it is hoped that this will help to boost the population.
You can help to protect the white rhino by supporting conservation projects, spreading awareness about the threats they face, and refusing to buy products made from rhino horns.
