Explanation: The national aquatic animal of India is the Ganges River Dolphin, scientifically known as Platanista gangetica. This species is endemic to the Ganges and Brahmaputra river systems and their tributaries, making it a unique and significant part of India's biodiversity. The Ganges River Dolphin is a freshwater dolphin and is one of the four species of river dolphins found in the world. It is also known as the Susu due to the sound it makes when it surfaces for air.
The Ganges River Dolphin was declared the national aquatic animal of India in 2009. This designation was made to highlight the importance of the species and to promote conservation efforts. The Ganges River Dolphin is critically endangered, facing numerous threats such as pollution, habitat degradation, and human activities like fishing and construction of dams. The Indian government has implemented several conservation measures to protect this species, including the establishment of protected areas and the enforcement of laws to prevent hunting and habitat destruction.
The Ganges River Dolphin is not only a symbol of India's rich biodiversity but also a cultural icon. It is revered in Hindu mythology and is often associated with the river Ganges, which is considered sacred in Indian culture. The choice of the Ganges River Dolphin as the national aquatic animal underscores India's commitment to preserving its unique wildlife and promoting environmental sustainability.
