Key Points

  • Baby rhinos weigh almost as much as a human adult shortly after their birth.
  • Unlike buffaloes or antelopes which learn to walk at once they take about a couple of days before being able to walk properly.
  • They’re staging a comeback. White rhino figures which once plunged between 50 – 100, have now reached 20,000.

Rhinos grow up to become the second largest land animals after elephants, but they’re born as adorable calves. Let’s look at five incredible baby rhino facts – all with pictures of course! – and discover what makes rhino calves so unique!

1. Baby Rhinos have a Gestation Period Almost Twice the Length of Humans!

Humans have a gestation period – the time it takes from conception to when a baby is born – of about nine months. For a rhino, the gestation period is 15 to 18 months! Female rhinos will wait between 2 and 3 years before giving birth to another calf.

Do rhinos have twins? Only on rare occasions.

Regardless of the number born, the young will remain close to their mother for 36 months following which they will wander off to lead a solitary existence. (White rhinos however are somewhat more gregarious and may form herds.)

2. Rhino Babies Can Weigh As Much As a Full-grown Adult!

On July 29, 2019, a rhino baby was born in the San Diego Zoo Safari that weighed 148 pounds just two days after birth! The baby, named Edward, already weighed 220 pounds by mid-August. That is to say, baby rhinos can weigh the same amount as humans just days (or weeks) after their birth!

3. Baby Rhinos have a Defense Against Attack!

While baby rhinos often weigh more than 100 pounds upon birth, that’s still a relatively small meal for predators like lions and tigers that live in the range of different rhino species. Thankfully for baby rhinos, they have a unique defense against would-be predators like lions, tigers, and leopards!

The skin of a rhino can be up to two inches thick, giving them a form of “armor plating” against predators like big cats! Baby rhinos are born with thick skin which helps defend them as they rapidly grow in the weeks and months after their birth. Still, predators will attack juvenile rhinos, attacks from prides of lions have been recorded on rhinos that weigh more than 2,000 pounds.

4. Baby Rhinos Take a Couple Days to Walk

A rhino calf won’t be able to immediately become mobile like many other species of mammals, instead it takes a calf two-to-three days to become steady on their legs. During this time, it’s up to their mom to take care of them! Male rhinos leave shortly after mating. Female rhinos are fiercely protective of their young during this period.

5. Baby Rhinos are on the Rebound!

White rhino populations have rebounded from 100 to more than 20,000


The population of white rhinos has rebounded steadily over the past 30 years. For example, while their population may have dipped as low as 50 to 100 in the wild, today it’s estimated there are around 20,000 white rhinos.

(Unfortunately, the northern white rhino population is now functionally extinct, as most the rebound has been in South Africa.)

White rhino breeding has been a success story in zoos across America. For example, the Virginia Zoo welcomed its first birth of a white rhino in July 2021. Earlier that same month, ZooTampa welcomed its own white rhino birth.

Several zoos around the world and the United States have successful white rhino breeding programs. The San Diego Zoo has placed particular emphasis on breeding white rhinos. The most recent birth at the San Diego Zoo occurred on August 22, 2021.
