Rhinoceroses are the largest land mammals after the elephants. 

There are five species of rhinos:
African: black rhino and white rhino
Asian: Greater one-horned rhino (Indian), Javan and the Sumatran

Almost declared extinct, yet with intensive conservation efforts, their latest population estimate is 20 405 – this includes both the northern and southern white rhino. The majority of its population is in South Africa which is currently experiencing a poaching crisis.

Known as the square-lipped rhino. It used its flat, square lip to cut and eat grass, making them known as the grazer, as opposed to black rhinos who are known as browsers. White rhinos only eat ground vegetation.

Tend to group in herds

Average height: 1.5 to 1.8 metres

Average weight: 1 800 to 3 000 kilograms (1.8 to 3 tonnes)

Critically endangered with a population estimate of 5 055 in the wild.

Known as browsers, they eat branches, twigs, bushes and shrubs. This is due to their upper lip, specifically adapted to help them forage.

Most active during the night-time, to forage and drink

Known for being shyer and more aggressive than the white rhinos

Good swimmers - they are able to dive down and feed underwater!

They were used in entertainment fights against elephants under the Mughal emperors influence, in South Asia

• The rhinos often won! But thankfully this sport is no longer practiced or permitted

Average height: 1.75 to 2 metres

Average weight: 1 800 to 2 500 kilograms (1.8 to 2.5 tonnes)

Closest relative to the woolly rhinoceros from the ice ages

Thought to be the most 'primitive' of rhino species due to its hairy skin and other ancient characteristics

Longest living mammal on earth!

They tend to spend their days lounging in ponds or mud wallows to keep cool

Average height 1 to 1.5 metres

Average estimated weight 500 - 960 kilograms (0.5 to 0.96 tonnes)

Rarest of the rhino species and possibly the rarest large mammal on earth

• Only found in Ujung Kulon national park
• Rarely photographed

Extremely vulnerable due to their small size

More likely to run away from an enemy than attack

Average height: 1.4 to 1.7 metres

Average weight: 900 to 2 300 kilograms (0.9 to 2.3 tonnes)
