Which one of the following is the national aquatic animal of India?

Result
Your answer: —  ·  Correct: C
Explanation

The Ministry of Environment and Forests notified the Ganges River Dolphin as the National Aquatic Animal.[1] The Ganges river dolphin is important because it is a reliable indicator of the health of the entire river ecosystem.[2]

The Gangetic dolphin is found in the Ganges and Brahmaputra Rivers and their tributaries in Bangladesh, India, and[2] Nepal. It can survive only in freshwater and is essentially blind. This mammal hunts by emitting ultrasonic sounds, which bounce off fish and other prey, enabling it to see an image in its mind.[1]

The other options - saltwater crocodile, olive ridley turtle, and gharial - are important species in India's biodiversity but do not hold the status of national aquatic animal.
