There are five species of rhinos in the world today, and all are endangered or threatened in some way. Three species are found in Asia and two are located in Africa. Thousands of years ago, rhinos were found in North America and Europe.
The black rhino and the white rhino live in Africa. The black rhino is critically endangered. The white rhino is the most abundant of the rhino species, but it is still threatened.
Rhinos can live in the wild for 30-35 years. They are herbivorous (plant eaters) and are some of the largest land mammals on earth. Some people believe the horns have healing properties and eat the ground up horns.
Rhinos are endangered mostly because of poaching for their horns. Their horns are made from keratin- the same protein found in our hair and fingernails.
