Two thousand White Rhinos will be released into wild reserves, due a conservation project organized by African Parks.
African Parks, a conversation group that co-manages protected areas in several African countries, acquired a large captive herd of the Southern White Rhinoceros (Ceratotherium simum simum) from a private estate in South Africa. This represents about 15% of the total population of the species, according to the New Scientist magazine (7 September 2023).
The herd mainly consists of wild-caught rhinos, and rhinos born in captivity.

To protect Black Rhinos from poachers killing them for their horn, conservationalists use a strategy of de-horning. The theory is: if the Black Rhino has no horn, then poachers won’t kill it, and the rhino lives longer. Rhino horns are more valuable than diamonds or gold on the black market in Southeast Asia. Over the past decade in southern Africa, steps were taken to save the rhinos from being poached, maimed, and killed for their horns.
De-horning is painless for the rhino, taking about 20 minutes. Veterinarians sedate the rhino, blindfold it, and insert earplugs, then use a chain saw to cut off the top of its horn, but only the section that does not contain nerves. When poachers cut of a rhino’s horn, they do it quickly at night, and they often damage the nerves or kill it. Rhino horns grow back, and veterinarians usually de-horn a rhino once every 18 months.
Scientists wanted to know more about rhinos that had been de-horned. New research has found some interesting results.

Is there a limit to how big animals can grow?
Joshua A. Krish poses this question in his article in Live Science (March 2023) and he says that there is a limit – animals can’t grow indefinitely.
The largest land animal is the African Elephant (Loxodonta africana) which is a mammal that reaches 250 centimetres (8 feet 4 inches) tall and 750 centimetres (25 feet) long, weighing about 6 metric tons (7 tons). It is not a meat-eating carnivore. It is an herbivore and eats grass, trees, bushes, fruit, and bark.

The Rhinoceros Ratsnake (Gonyosoma boulengeri) is a non-venomous colubrid reptile in the Colubridae family. It is also known as the Vietnamese Longnose Snake.
The Rhinoceros Ratsnake is green with a prominent, distinctive protrusion of the front of its nose. The pointy protrusion—which looks like a rhinoceros horn—has scales like the rest of its body. It has 19 rows of dorsal (back) scales to its mid-body.

The Asiatic Rhinoceros Beetle (Oryctes rhinoceros) is a small insect in the Scarabaeidae family of scarab beetles. It is also known as the Coconut Rhinoceros Beetle or the Coconut Palm Rhinoceros Beetle.
The Asiatic Rhinoceros Beetle is glossy black with a blue-green sheen, and a large horn, like the horn of a rhinoceros. It has black wing cases, called elytra. Each wing case (elytron) is covered with white wax and a number of small nodules or lumps. Its antennae are short. It has spikey hairs on its six legs.

The African Rhinoceros is a distinctive animal due to its thick, armoured skin and large curved horn. Rhinoceros means ‘nose with a horn.’
The critically endangered Black Rhinoceros (Diceros bicornis) is also called the Hook-Lipped Rhinoceros. The White Rhinoceros (Ceratotherium simum) is also called the Square-Lipped Rhinoceros. Most rhinos in zoos are the Southern White Rhinoceros.
Some animals are described as ‘rhinoceros’ in their scientific or common name because they have a horn that looks like a rhinoceros horn.
The Rhino Catfish (Pterygoplichthys scrophus) from South America is a fish with a ridged, armoured body and two horn-like protrusions from its head that looks like the horns of a rhinoceros. The protrusions are actualy nostril flaps so that water doesn’t get up its nose. Its body is completely covered in small plates that look like armour.

What do Rhinoceros teeth look like?
The White Rhinoceros (Ceratotherium simum) has a wide, flat fronted mouth with broad lips.
It is a grazer, and eats short grass. Therefore, the White Rhinoceros has large, regular, flat-topped teeth to grind the grass.

What is the rhinoceros horn made of?
The rhinoceros horn is not a true horn, because it is not made of keratin.
The horn of a rhinoceros is made of a solid mass of compressed hair.

What are Africa’s ‘Big Five’ animals?
Africa’s Big Five animals were originally the five animals that big-game hunters believed were the most difficult to hunt on foot. Nowadays, the five animals are the animals that tourists want to see and photograph. They are all land mammals.

The Rhinoceros Iguana (Cyclura cornuta) is a large reptile – it is a lizard.
The Rhinoceros Iguana is grey-brown or grey-green. It has a bony horn-like lump on its nose, which looks like a rhinoceros horn. It has a crest of pointed scales from the nape of its neck to to the tip of its long tail. It has blue eyes.

The Malayan Tapir (Tapirus indicus) is also called the Asian Tapir, and is the largest of all the tapirs. It is related to horses and rhinoceroses. It is an ungulate (hoofed) mammal.
The Malayan Tapir is black with a dull-white strip of fur from its shoulders to its tail. It has a short prehensile trunk (like an elephant’s trunk but much shorter). Its trunk can grab branches and leaves or pick fruit from trees. It has a low crest of hair from the crown down the back of the neck. Its round, dark ears have white edges. Its tail is short and stubby.
They have hoofed feet (hooves). They have four toes on their front feet and three toes on their back feet.

The Black Rhinoceros (Diceros bicornis) is also called the Hook-Lipped Rhinoceros. It lives in eastern and southern Africa and it is critically endangered.
It is not actually black: it is grey or dark grey. It is hairless, except for hair on the ears and tail tuft.
It has a wide mouth, a broad body, a large head, a short neck, and stumpy legs with three toes on each foot. It has two horn-like keratin growths, one behind the other. The front horn is larger than the second horn. The front horn is about 50-140 centimetres (2 to 4.5 feet) long, which is longer than the horn of White Rhinoceroses. Sometimes, a third, smaller horn may develop.
It can grow to about 1.8 metres (6 feet), which is about half the size of a White Rhinoceros.

The White Rhinoceros (Ceratotherium simum) is also called the Square-Lipped Rhinoceros. Most rhinos in zoos are Southern White Rhinoceroses. There are only two Northern White Rhinoceroses (Ceratotherium cottoni) left in the world – two females – and they are in the Ol Pejeta Conservancy in Kenya under 24-hour armed guard. There were three Northern White Rhinos, but Sudan, a male, died of old age on 19 March 2018 at the age of 45.
