Contents9
- ASaltwater crocodile
- BOlive ridley turtle
- CGangetic dolphin
- DGharial
Show answer
Answer: (C) Gangetic dolphin
The Gangetic River Dolphin (Platanista gangetica) was declared India's National Aquatic Animal in 2009 by the then Prime Minister.
It is a freshwater dolphin found in the Ganga-Brahmaputra-Meghna and Karnaphuli-Sangu river systems.
It is practically blind and navigates using echolocation (like sonar).
It is listed as Endangered on the IUCN Red List and is protected under Schedule I of the Wildlife Protection Act, 1972.
Why are the other options wrong?
- Saltwater crocodile — found in Sundarbans and Bhitarkanika, but it is not the national aquatic animal.
- Olive ridley turtle — famous for mass nesting (Arribada) at Odisha's coast, but not the national aquatic animal.
- Gharial — a critically endangered crocodilian found in North Indian rivers, but again not the designated national aquatic animal.
Quick revision of national symbols:
- National Animal = Bengal Tiger
- National Bird = Indian Peacock
- National Aquatic Animal = Gangetic Dolphin
- National Heritage Animal = Elephant.
The Gangetic River Dolphin was declared India's National Aquatic Animal in 2009, making it the official symbol representing India's freshwater ecosystems.
This endangered freshwater dolphin is practically blind and navigates using echolocation, found only in the Ganga-Brahmaputra-Meghna river systems.
The question tests knowledge of India's official national symbols - National Animal (Bengal Tiger), National Bird (Peacock), National Aquatic Animal (Gangetic Dolphin), and National Heritage Animal (Elephant).
