India is a country with a rich, varied ecology. The subcontinent is home to deserts, tropical forests, grasslands and mountains. This is reflected in its large variety of animals, from elephants to monkeys to yaks to tigers.
Many of the animals that live in India today are endangered. But what of the animals India has already lost? India's extinct animals are among the most varied - and sometimes strangest, of all.
The Indian Cheetah, or Asiatic cheetah, became extinct in India in 1948. It lives on in Iran, but is critically endangered. It is estimated that less than 100 Indian cheetahs remain in the wild.
The Indian auroch was a gigantic species of cattle. It was stocky and had characteristically large horns compared to its European cousins.
The Sivatherium giganteum was an ancient Indian grazing mammal. It was similar in appearance to a giraffe, but chunkier and with a moose-like head.
The Gigantopithecus blacki was an ancient species of ape. It weighed over half a tonne and stood 3 metres tall. This gave it the title of the largest ape ever to have existed.
The Pink-headed duck was a slim, brightly coloured diving duck. While it is technically classified as Critically Endangered, no living examples have been found since the 1950s.
