Which of the following is the National Aquatic Animal of India?
- A.Gangetic dolphin
- B.Olive ridley turtle
- C.Mahseer
- D.Dugong
Show answer
Correct answer: A. Gangetic dolphin
Explanation
The correct answer is A, Gangetic dolphin. Platanista gangetica, the South Asian river dolphin of the Ganga, Brahmaputra and Meghna systems, was notified as the National Aquatic Animal in 2009. It is nearly blind and hunts by echolocation, it surfaces to breathe, and it is treated as an indicator of the health of the river, which is why the declaration came alongside the work on the Ganga.
Option B, the olive ridley turtle, nests in huge numbers at Gahirmatha in Odisha and is protected, but it holds no such title. Option C, the mahseer, is a large freshwater game fish of Himalayan rivers and is threatened, not a national symbol. Option D, the dugong, is a marine mammal of the Gulf of Mannar and the Andaman waters, and is sometimes confused with the dolphin because both are protected aquatic mammals.
