The fascinating rhino facts below are brought to you by International Rhino Foundation. Enjoy!
- A group of rhinos is called a ‘crash’.
- White rhinos aren’t white (and black rhinos aren’t black). The white rhino’s name is taken from the Afrikaans word describing its mouth: ‘weit’, meaning ‘wide’. Early English settlers in South Africa misinterpreted the ‘weit’ for ‘white’.
- Rhinos are fast! They can run up to 30–40 miles per hour, which may not sound like much, but if one is running straight towards you it feels like a NASCAR race car is coming your way.
- Rhino pregnancies last 15-16 months. Wow!
- A rhino’s skin is much softer than it looks, and is actually quite sensitive to sunburns and insect bites (that’s why rhinos like rolling in the mud so much – it helps to protect them from the sunburns and insects).
- Contrary to the common myth, there is no evidence that rhinos stamp out forest fires!
- The white rhino is the largest rhino (and the largest land mammal after the elephant). They can weigh up to 6,000 pounds. The Sumatran rhino is the smallest rhino, weighing in at a mere 1,300–2,000 pounds.
- Rhinos have poor eyesight, but very well-developed senses of smell and hearing. They will charge at you when startled–the best way to escape is by climbing a tree, if one is handy!
- African rhinos have a symbiotic relationship with oxpeckers, also called ‘tick birds’. In Swahili, the oxpecker is called ‘askari wa kifaru’, which means ‘the rhino’s guard’. The oxpecker eats ticks and other insects it finds on the rhino, and creates a commotion when it senses danger.
- Most rhinos use piles of dung to leave ‘messages’ for other rhinos. Nuances in the smell of dung can tell a rhino a lot about others in the area. Each rhino’s smell identifies its owner as unique. The smell is different for young vs. adult animals, for males vs. females, and females in estrus vs. non-reproductive females. Combined with urine left along trails, dung piles create invisible ‘borders’ around a rhino’s territory.
- Rhinos have existed on earth for more than 50 million years, and once roamed throughout North America and Europe (as well as Asia and Africa).
- Throughout their history, rhinos have been a very diverse group. The extinct rhino, Paraceratherium, was the largest land mammal that ever lived and resembled a big, muscular giraffe. Telecoeras was a single-horned, hippo-like grazer common in North America.

The book, The Wonderful Wizard of Oz, written by L. Frank Baum and illustrated by W.W. Denslow, differs a lot from the classic movie and actually has a reference to rhinos. Dorothy, the Scarecrow, the Tin Man and the Lion each get to meet the Wizard individually and he appears differently to each of them. To Dorothy, he appears as a huge head, to the Scarecrow as a beautiful woman, to the Lion as a great ball of fire, and to the Tin Man as a terrible beast. The beast is described as such: ‘It was nearly as big as an elephant, and the green throne seemed hardly strong enough to hold its weight. The Beast had a head like that of a rhinoceros, only there were five eyes in its face. There were five long arms growing out of its body and it also had five long, slim legs. Thick woolly hair covered every part of it, and a more dreadful-looking monster could not be imagined.’
Somehow, this never made it to the film version.
- Three of the five surviving rhino species–black, Javan, and Sumatran–are Critically Endangered, which means there is at least a 50% chance that these species will become extinct within three generations (for rhinos, this means about 30-60 years).
- The ancient woolly rhino, whose entire body was covered in a thick, shaggy coat, was hunted by early humans and is depicted in cave paintings dating back more than 30,000 years ago. The Sumatran rhino is the closest living relative of the extinct woolly rhino, and they’ve got the hair to prove it!
- The black rhino has a prehensile lip which allows it to feed on trees and shrubs (the other African species, the white rhino, has a long, flat lip for grazing on grasses).
- The Javan rhino is the rarest land mammal in the world. Less than 50 individuals survive in the wild!
- Not all rhinos are solitary. Both black and white rhinos commonly live in extended family groups, typically comprised of females and calves.
- Although science has proven rhino horn to be void of any curative medicinal properties, it is still illegally used in traditional Chinese medicines to treat a variety of ailments–from fevers to boils, liver dysfunction, cancer, and even devil possession. Contrary to a common misconception, one of the few things rhino horn is not used for is libido. The burgeoning demand for the horn stems almost exclusively from East and Southeast Asia–predominantly from China and Vietnam–and has fueled unprecedented poaching of these magnificent animals. As a result, they are now poached at a rate of at least one per day. In 2010, at least 333 rhinos were killed by poachers in South Africa alone. Already this year, the country has lost over 280!
- Sumatran, black and white rhinos all have two horns, Javan and greater one-horned rhinos have one horn (and some female Javan rhinos don’t appear to have a horn at all).
- The most famous piece of rhino artwork is Albrecht Durer’s woodcut, ‘The Rhinoceros’, printed in 1515. It (not entirely accurately) depicts a greater one-horned rhino sent as a gift from the King of Portugal to Pope Leo X, and has been reprinted countless times over the past 500 years.
- The word rhinoceros comes from the Greek words, rhino (nose) and ceros (horn).
- Depending on the species, rhinos can live to between 35 and 50 years old.
- Rhino horns are made of keratin, the same material that makes up your hair and fingernails.
- The closest living rhino ‘relatives’ are tapirs, horses and zebras.

Unfortunately we can’t afford just one day for these wonderful animals anymore……they are in desperate of help EVERY day now…..
Totally agree Betty, and a new port in a bio diverse area of Mozambique has been agreed which will not only be a disaster for the marine life but their is to be a tar road funded by the chinese from the South African border post to the new Techobanine port which goes through a new elephant corridor which has rhinos as well as the biggest tuskers in the world – easy access to Africa’s wildlife and the port and industrial area which will have all of it’s workforce brought in from China. This slaughter of Rhinos, Elephants (you just have to see the amt of orphans coming in to DSWT to see ivory poaching is increased dramatically) and obviously the port will have easy access to Sharks and whatever other animals are deemed edible or suitable for traditional medicine (which seems to be every animal with a pulse).
If a rhino’s horn is carefully and humanely cut off about three inches above its base (anesthetizing the animal first), the horn will grow back in two years and the rhino suffers no long term consequences and – most importantly – isn’t KILLED. A South African rancher, John Hume, has many rhinos whose horns he cultivates. While I wish we didn’t have to cut off the horn to begin with, isn’t this method much better than killing the animal? The horn cut is done by a trained veterinary. After the rhino wakes up, he returns to grazing in the field. We need to be smart about our wildlife conservation and this is just one idea.
