Explanation:

Gharials once inhabited all the major river systems of the Indian Subcontinent, from the Irrawaddy Riverin the east to the Indus River in the west. Their distribution is now limited to only 2% of their former range.

The Leatherback Turtle (Dermochelys coriacea) is the only existing species of the family Dermochelyidae. They are the largest of living sea turtles, growing up to 2 metres and weighing as much as 900 kg.

The barasingha, also called swamp deer, is a deer species distributed in the Indian subcontinent. Populations in northern and central India are fragmented, and two isolated populations occur in southwestern Nepal

All three are endangered in India.
