Patna, in Bihar, will soon have first research centre to conserve the dwindling number of Gangetic River Dolphins. These creatures inhabit the tributaries of the Ganga River, in India, Bangladesh and Nepal. In India, only around 2,000 Gangetic river dolphins are left. The Gangetic river dolphin is India’s national aquatic animal. They are blind and move about in the water using echo-location.

A census in the river, in Bihar, is also planned. Poaching has left these mammals in the endangered list. The Vikramshila Gangetic Dolphin Sanctuary in Bihar’s Bhagalpur district is trying its maximum to increase their numbers. It is the lone dolphin sanctuary in India. It covers 50km along the Ganga River.

Freshwater Dolphin are also found in the Yangtze river in China, the Indus river in Pakistan and the Amazon river in South America.
