Explanations:The national aquatic animal of India is the Ganges River Dolphin, also known as the Susu or Platanista gangetica. This species is a freshwater dolphin that is endemic to the Ganges and Brahmaputra river systems in India, Bangladesh, and Nepal. The Ganges River Dolphin is a critically endangered species and is protected under the Wildlife Protection Act of India.
The Ganges River Dolphin is a unique species that has adapted to living in freshwater environments. It is characterized by its elongated beak, which can be up to 20% of its body length, and its poor eyesight, which has led to the development of echolocation for navigation and hunting. The species is an important indicator of the ecological health of the Ganges and Brahmaputra rivers, as it is sensitive to pollution and habitat degradation.
The choice of the Ganges River Dolphin as the national aquatic animal of India reflects the country's commitment to the conservation of its unique biodiversity and the protection of its natural resources. The Ganges River Dolphin is not only a symbol of the ecological health of the rivers but also a cultural icon, with a rich history in Indian mythology and folklore.
It is important to note that while the Ganges River Dolphin is the national aquatic animal, other species such as the Olive Ridley Turtle and the Blue Whale are also significant in India's biodiversity and conservation efforts. However, they are not designated as the national aquatic animal. The Olive Ridley Turtle is known for its mass nesting events on Indian beaches, while the Blue Whale is a marine mammal and not endemic to India's rivers.
The Dugong, another marine mammal, is found in coastal waters and is not endemic to India's rivers. It is not the national aquatic animal of India, although it is protected under the Wildlife Protection Act of India.
Understanding the national symbols of a country, such as the national aquatic animal, is important for students preparing for competitive examinations like the UPSC, SSC, and Bank PO, as these symbols often feature in questions related to general knowledge and current affairs.
