How Much Does a Blue Whale Weigh? Animalia Facts

Rhinoceros: odd-toed ungulates (hoofed mammals) in the family Rhinocerotidae

While nearly 100 known rhinoceros species have existed throughout the eons, there are currently five species of living rhinos

Two rhino species can be found in Africa and three species can be found in Asia

The two African species are the black rhino (Diceros bicornis) and the white rhino (Ceratotherium simum)

The three Asian species are the Sumatran rhino (Dicerorhinus sumatrensis), the Javan rhino (Rhinoceros sondaicus), and the greater one-horned rhino (Rhinoceros unicornis)

While 500,000 rhinos roamed Africa and Asia at the beginning of the 20th century, rhino numbers dropped to 70,000 by 1970

Now, as few as 29,000 rhinos remain in the wild

The remaining rhinos can be found outside national parks and reserves

Three species of rhino (black, Javan, and Sumatran) are critically endangered

Rhinos vary in size and weight depending on the species

On average, their height is between 33 and 5 feet, their length is between 65 and 13 feet, and their weight is 1,320 to 2,090 pounds

Black rhinos are the smaller of the two African rhino species

On average, their height is 52 feet and their weight is between 1,720 and 3,080 pounds

The white rhino is the larger African species, weighing 3,080 between and 7,920 pounds and standing at a height between 5 and 6 feet

Javan rhinos are 46 to 58 feet in height and can weigh between 1,984 and 5,071 pounds

The greater one-horned rhino is the largest of the rhino species, with height ranging from 575 to 65 feet and weight ranging from 4,000 to 6,000 pounds

The rhinoceros gets its name from one of its most notable features: its horns

The word rhinoceros come from the Greek words rhino meaning “nose” and ceros meaning “horn” The number of horns that a rhino has varies on the species

The two African species (the black rhino and the white rhino) and the Sumatran rhino have two horns, while the Javan rhino and one-horned rhino have one horn

Rhinos’ appearances vary depending on the species

The Sumatran rhinos are the smallest of the living rhinos

The Sumatran rhinos are the smallest of the living rhinos

They are covered with long hair and are more closely related to the extinct woolly rhinos than any of the other rhino species alive today

The greater one-horned rhino is identified by a single black horn, which is about 8 to 25 inches long

The Javan rhino is very similar in appearance to the closely-related one-horned rhino, but the Javan rhino has a much smaller head and less apparent skin folds

Javan rhinos are a dusky grey color and have a single horn of up to about 10 inches

Both species of African rhinos, black and white rhinos, are the same color

Of the two African species, black rhinos are the smaller species

The most notable difference between white and black rhinos is their hooked upper lip

White rhinos are known for their square lip, which distinguishes them from the black rhino

Black rhinos are browsers rather than grazers, and their pointed lip helps them feed on leaves from bushes and trees

Black rhinos have two horns, and occasionally a third, small posterior horn

All five species of rhinos are herbivores, eating mainly vegetation

They spend most of their time browsing and grazing through their natural habitat in search of plants and grasses to eat

The specific types of food that each of the species eats depend upon their habitat and location

Rhinos are one of the few remaining megaherbivores, which are plant-eaters that weigh more than 2,000 pounds

Their habitat depends on the species

For example, the Sumatran rhino’s habitat is dense highland and lowland tropical and subtropical forests

Meanwhile, the white rhino can be found in African grasslands

While rhinos once roamed great portions of Africa and Asia, their range has decreased dramatically in recent years

Rhinos can currently be found in Borneo and Sumatra, Namibia, the Eastern Himalayas, and Coastal East Africa

Their location depends on species

For example, the Sumatran rhino can be found on the Indonesian islands of Sumatra and Borneo

Meanwhile, the white rhino and the black rhino can be found in Africa

Female rhinos give birth to a single calf, which can weigh over 100 pounds

Rhino breeding patterns depend on the species and its habitat

The mother may stay with her calf for up to four years unless she has another baby, in which case she pushes her older calf into independence to make way for the new arrival

Sumatran rhinos are the exception, where the mother will only stay with the calf for two to three years, even if the mother does not have another newborn for another two years

For the Sumatran rhino, only two captive females have reproduced in the last 15 years

This covering later becomes sparse, bristly and near black in older animals

White rhinos, which have a complex social structure, have different breeding patterns

The home range for adult females can be more than seven times larger than males, depending on habitat quality and population density

Breeding females are prevented from leaving a dominant male’s territory, which is marked and patrolled by its owner on a regular basis

Males will compete over a female, which can cause a conflict where the males will use their horns and massive size to inflict wounds on their competitors

Several species of rhinos are endangered with small populations remaining

For example, the remaining Sumatran rhinos live in small, fragmented non-viable populations

Meanwhile, there are only 58 to 68 Javan rhinos remaining, which only live in Ujung Kulon National Park in Java, Indonesia

The two species of African rhinos live in home ranges that can sometimes overlap with each other

Their feeding grounds, wallows, and water holes may be shared among other local rhinos

Of the two African species, the black rhino is usually solitary, while the white rhino tends to be more social

White rhinos have complex social structures

Groups of sometimes 14 rhinos may form, which typically includes females and their calves

White rhino adult males defend territories of roughly one square mile, which they mark with vigorously scraped dung piles

The one-horned rhino is solitary, except when adult males, or rhinos nearing adulthood, gather at wallows or to graze

Rhinoceroses’ lifespans vary on species

Javan rhinos are the most threatened of the five rhino species and are found in only one protected area in the world

The species is extremely vulnerable to extinction due to natural catastrophes, habitat loss, diseases, poaching, and potential inbreeding

Sumatran rhinos compete with the Javan rhino for the title of most threatened rhino species

While surviving in possibly greater numbers than the Javan rhino, Sumatran rhinos are more threatened due to habitat loss and fragmentation

The remaining animals survive in small, fragmented non-viable populations, and with limited possibilities to find each other to breed, its population decline continues

Just two captive females have reproduced in the last 15 years

Poaching is the largest threat to the one-horned rhino

Habitat loss due to expanding human populations is another major threat

In Africa, wildlife crime is the biggest threat to both black and white rhino

The white rhino has been near extinction for decades to the rampant poaching for rhino horn

Habitat loss is another major threat to both species

Javan rhinos are the most threatened of the five rhino species and are listed as Critically Endangered with only 58 to 68 individuals remaining

Sumatran rhinos are also listed as Critically Endangered with a population of 80

One-horned rhinos came very close to extinction

By the start of the 20th century, around 200 wild greater one-horned rhinos remained

However, conservation efforts have brought their numbers up to about 3,500 rhinos

The one-horned rhino is now classified as Vulnerable

While black rhino numbers have doubled from their historic low 20 years ago to between 5,042 and 5,455, they are still classified as Critically Endangered

Meanwhile, the other African species, white rhinos are the only of the five rhino species not listed as endangered

With a population size of less than 19,600 to 21,000, white rhinos are classified as Near Threatened

Northern white rhinos, a subspecies of rhino, are on the brink of extinction

In 2018, the last male northern white rhino, Sudan, died

The two remaining females, who reside at Ol Pejeta Conservancy in Kenya, are too old to reproduce

Scientists used sperm from both Sudan and another male that died earlier to fertilize two eggs from the females, Fatu and Najin

As the population of rhinos continues to decrease, conservation groups and local governments are working to protect these endangered species

The illegal wildlife trade and poaching are some of the largest threats to these species

To protect rhinos from poaching, African countries began working to protect their rhinos, China no longer approved the use of rhino horn for traditional medicines, and countries in the Middle East promoted dagger handles made of synthetic materials

These efforts reduced rhino poaching drastically

Conservation efforts, including intensive anti-poaching and habitat protection efforts, have helped some wild rhinos make a comeback

For example, poaching has been almost eliminated in Indonesia, largely due to the country’s Rhino Protection Units

The greater one-horned rhino has made a dramatic recovery thanks to conservation efforts, and the recovery is considered one of the greatest conservation success stories in Asia

At the start of the 20th century, there were only 200 remaining greater one-horned rhinos

There are now more than 3,700 rhinos

The species was saved from the brink of extinction through strict protection and management action from Indian and Nepalese authorities and their partners

Sudan, a 43-year-old northern white rhino, is the last male of his subspecies

He is not able to naturally reproduce with the remaining two females, so scientists were hoping to use in-vitro fertility treatments

Their massive bodies are covered with thick armor and weigh a lot

So it isn’t uncommon to wonder how much does a rhino weigh?

Five species of these huge mammals still are roaming the surface of the earth

Among them, the white rhino is the largest of all

Their weight ranges from around 2700 kilograms that are about 6000 pounds

Adults of these larger species have a massive weight of 3 to 5 tons

Rhinos have massive bodies

Their huge shoulders carry a lot of weight

Even their horns weigh around 15 to 4 kilograms

Many signs of bone health issues such as bone degeneration, infection, etc were found in the extinct and existing species of the horned animal

Many scientists are currently studying the detriment of long-term bone health issues in the giants

How much do rhinos weigh through different life stages?

An animal can weigh differently in different conditions in its life

Many scientists stand amazed at the fact that something that lives on grass can grow that big

Again, a rhino in the wild may weigh differently than the one in captivity

Different species also weigh differently

Such as the White Rhino is the largest of all and the Sumatran Rhino is the smallest species existing

Their average weight is determined by examining a lot of specimens over many years

Weight of a rhino baby

At birth, the baby of a White Rhinoceros can weigh from 50 to 60 kilograms

The baby starts walking after a few hours of its birth and lives totally on its mother’s milk for 2 or 3 weeks

The milk has so much fat in it that the baby gains 15 to 2 kilograms daily during the first few days of its birth

After a few weeks, the mother familiarizes her calf with fresh grass

The calf then starts eating its first vegetation but it also drinks breast milk for about 2 years

During this time it grows physically to being an adult and learns survival skills from the mother

Weight of an adult rhino

The mother feeds the calf with her milk

The rich milk helps it to grow fast

After some time the calf starts eating grass

After 3 to 4 years, the giant becomes an adult and can leave the mother and live in the wild alone

During this time their average weight ranges from 3 to 5 tons

Only a few of today’s existing adult mammal species weigh over a ton and the horned African giant is one of them

Different species Weight Comparison

Five species of massive animals are still roaming the planet’s forests and deserts

These include The African White and The Black Rhino, The Greater One-Horned species, The Sumatran Rhinoceroses, and The Javan Rhinoceroses

White Rhinoceros

White Rhinoceroses are the biggest Rhinoceros breed alive

The gestation period of these creatures lasts for about 16 months

It gains 15 to 2 kilograms daily during the few days of its birth

Males grow faster than females

After 3 to 4 years an adult can be a lot heavier

Their average weight ranges up to 2700 kilograms

Females are less heavy than males of the same family

Black Rhinoceros

Females weigh less than males

Their gestation can last for about 15 to 16 months

The calf is about 35 to 50 kilograms at birth, which is about 75 to 110 pounds

The mother’s rich milk helps the calf to grow a lot faster

They leave their mothers after about 3 to 4 years

The greater one-horned Rhinoceros

These Indian species of giants can be about 50 to 65 kilograms at birth

About 60 kilograms is considered to be a good weight for these infantsAfter 4 to 6 years the calf reaches its mature age

During this time, they can weigh from around 1600 to 2700 kilograms, about 4000 to 6000 pounds

The males are heavier than the females

An average male in the wild carries about 2200 kilograms and an average female carries about 1600 kilograms

Sumatran Rhinoceros is the smallest breed of all rhinoceros species

An adult’s body carries about 1300 to 2100 pounds that are 600 to 900 kilograms

Males are heavier than femalesThe infants can be about 40 to 60 kilograms that are about 88 to 132 pounds

An infant can have a weight of 45 to 69 kilograms(88 to 150 pounds)

During this, they weigh about 900 to 2300 kilograms(Around 2000 to 5000 pounds)

The females weigh little more than the males

The weight comparison between two different mammals always depends on the families that are being compared

The hippo has 2 living species currently and the rhino has 5 species

If the biggest breed of both mammals is compared, that is the white rhinoceros and the common hippo, the horned giants obviously win

Rhinoceros and hippopotamuses are the two biggest land mammals currently existing on the planet

The hippo despite being more ferocious than the horned beast is smaller in size

The average male armored giant can be up to 2700 kilograms heavy

Whereas the average male hippo can only weigh from 1500 to 1800 kilograms

The Sumatran rhinoceros are way heavier than the pygmy hippos

The pygmy hippos are only 400 to 600 pounds heavy

Whereas the Sumatran horned giants are 1300 to 2100 pounds heavy

Scientists are still studying the weight distribution of these huge animals to learn new things

They believe there is more to know from the question of “how heavy is a rhino?”

The giant horned animal is the second-largest living mammal on the planet

Though they live on vegetation, their body has a lot stronger structure

Rhinos’ weight changes during the different stages of life

Different species also are differently heavy

Lastly, a rhinoceros is obviously heavier than a hippo
