From UPSC perspective, the following things are important :
Prelims level: Indian Gharial

One may often get confused between the Mugger, Gharial and the Saltwater Crocodile. Note the differences about their IUCN status, habitat (freshwater/saltwater) etc..
Gharials

Into the wild
- A major chunk of gharials in India is found in the Chambal River, which has about 1,000 adults.
- The Ghaghara acts as an important aquatic corridor for gharials in Uttar Pradesh. The river is a major left-bank tributary of the Ganges.
- Like Uttar Pradesh, Bihar too is releasing gharials in the Valmiki Tiger Reserve as part of restocking the wild population. Unlike crocodiles, gharials do not pose any danger to humans.
Ambitious project in Punjab
- The gharial reintroduction in the Beas Conservation Reserve is an ambitious programme of the Punjab government.
- The reptiles were commonly sighted in the Beas River till the 1960s but later became extinct.
