Once thought to be anti-social, new research reveals that rhinos often gather at night in sociable groups around watering holes.
There are two African rhinos, the White rhino and the Black rhino and three Asian rhinos, the Indian one-horned rhino, the Sumatran rhino and the Javan rhino. Some of these species are close to extinction, and the demand for rhino horn by people who believe it has healing properties, means that rhino are being poached and numbers continue to fall.
Rhinos have lived on earth for over 40 million years but habitat loss from human encroachment and poaching for their horn means they need our protection. In the wild, the only predator of adult rhinos is man.
