Did you know?
- Black rhinoceros are part of the Rhinocerotidae family, which they share with other rhinos.
- There are five species of rhino in the world: two in Africa and three in Asia.
- Rhino horns are made of keratin, or densely compressed hair, the same material as our fingernails!
- An adult can weigh more than one ton (2,000 pounds).
- A female will have one calf.
Black rhinoceroses are imposing animals, with an adult weighing in at more than 1 ton. Their horns are large as well: the front (anterior) horn is larger and measures up to 55 inches, while the rear (posterior) horn is smaller and measures up to 22 inches. Although they have poor eyesight, they have keen senses of smell and hearing, which help them communicate and observe their surroundings.
Young and Family
Black rhinoceros are semi-social and territorial animals; adult females have overlapping ranges while males are generally solitary. Black rhino ranges vary greatly depending on the habitat and, to some extent, on sex and age. Females will have a gestation period between 14 and 16 months, and then give birth to one calf.

We care about black rhinos
The black rhinoceros has been pushed to the brink of extinction by illegal poaching for their horns, and to a lesser extent by loss of habitat.
We are working to help protect rhinos through the Saint Louis Zoo WildCare Institute Center for Conservation in the Horn of Africa. The Saint Louis Zoo also participates in the Black Rhino Species Survival Plan, a cooperative breeding program that helps ensure a healthy population of animals. Learn more about how we are helping rhinos in the wild.
