NEW DELHI, October 5 — The nation observed National Dolphin Day on October 5, 2026, spearheading public awareness and river-conservation initiatives coordinated by the Ministry of Environment, Forest and Climate Change (MoEFCC) alongside the National Mission for Clean Ganga (NMCG) to safeguard India's National Aquatic Animal, the Gangetic River Dolphin.
The Gangetic River Dolphin (Platanista gangetica) is an apex freshwater mammal inhabiting the Ganga, Brahmaputra, and Meghna river basins across India, Nepal, and Bangladesh. Being functionally blind, the mammal navigates and hunts prey via echolocation emitting high-frequency ultrasonic clicks. Through targeted habitat protection and anti-poaching vigilance under the Prime Minister's flagship "Project Dolphin", river reaches spanning Uttar Pradesh, Bihar, and Assam have registered steady population stabilization over recent ecological census cycles.
Wildlife biologists emphasize that river dolphins serve as vital bio-indicators of overall freshwater ecological integrity, functioning much like tigers in terrestrial forests. Continuous industrial effluent treatment under Namami Gange has improved river dissolved oxygen levels, supporting riverine biodiversity corridors.
Endangered species classifications, flagship conservation initiatives, and river ecology are recurring themes in UPSC Civil Services, State PSCs, and forestry examinations. Candidates should note that the Gangetic River Dolphin was formally declared India's National Aquatic Animal in 2009, is classified as 'Endangered' on the IUCN Red List, and enjoys maximum legal protection under Schedule I of the Wildlife (Protection) Act, 1972.
