Ravindra Kumar Sinha is a Padma Shri awarded Indian biologist and environmentalist. He served as Vice-Chancellor of Shri Mata Vaishno Devi University from 2019-2023 and also served in Nalanda Open University. Previously he was the Head of the Department of Zoology at Patna University, and is a pioneer researcher and wildlife conservationist, famous for his efforts for the conservation of Gangetic Dolphins, he is popularly known as the "Dolphin Man of India".

His scientific research and conservation campaign for the last 4 decades have been crucial to the efforts of saving the South Asian river dolphin from extinction. In response to the awareness of the urgency of protecting the Ganga River dolphin raised by Sinha, the Government of India designated this Dolphin as the National Aquatic Animal of India^[1][2] in 2009.

A member of the IUCN Species Survival Commission^{[citation needed]} and the National Ganga River Basin Authority, his contributions are reported in the establishment of the Vikramshila Gangetic Dolphin Sanctuary, Bhagalpur and he is a recipient of the Order of the Golden Ark of the Netherlands.^[3] The Government of India awarded him the fourth highest civilian honour of the Padma Shri, in 2016, for his contributions to environmental conservation.^[4]

Prof. R K Sinha conducted surveys of the entire length of the Ganges and most of its tributaries in India and Nepal to assess the distribution, population status, ecological requirements, and threats to the dolphin. The animal was facing extinction due to indiscriminate poaching and habitat degradation and loss in many areas. Sinha organized education and awareness programs among the local fishermen as well as secondary and college students. The national and international print and electronic media widely promoted his research and conservation efforts, attracting the attention of both national and international policy makers, executives, and scientific communities.

He was designated as the "Dolphin Man of India" by S.Z. Qasim, Member of the Planning Commission, in the International Seminar on River Dolphins in Delhi in 1992. Sinha was invited to membership of the IUCN (International Union for Conservation of Nature) headquartered in Geneva, Switzerland in 1994; was elected Fellow of the Linnean Society of London in 1996, and elected Chairman of the Asian River Dolphin Committee in 1997 under the aegis of the IUCN.

Sinha has published over 100 research papers in peer-reviewed journals, four books, and over 40 technical and research reports primarily on the Ganges dolphin, river biodiversity, and Ganges pollution. In 2001, he accomplished the first ever rescue and translocation of a stranded pregnant dolphin.

This Gangetic dolphin, which Dr. Sinha is trying to conserve, is one of the only three obligate fresh water dolphins in the world, one of the most endangered mammals on earth; an endemic species of the Indian subcontinent; a natural aquatic heritage of India and an indicator species of the health of the Ganga system. The Gangetic dolphins have long been poached for the extraction of their body oil as a fish attractant for use in oil fishery. Sinha discovered an alternative made from fish scraps. By effectively communicating and popularizing this alternative among Indian fishermen, dolphin poaching has been significantly reduced. This discovery was published in the internationally reputed journal Biological Conservation (London). Sinha developed the Conservation Action Plan for the Gangetic Dolphin in 2010 which was enthusiastically accepted by the Government of India.

Sinha is also known for his contribution to two famous documentaries Alert on the Ganges (26 minutes, French) and Mr. Dolphin Sinha: Think Globally and Act Locally (52 minutes, English) both produced by Mr. Christian Gallissian in 2007.

Sri Jairam Ramesh, Union Minister of Environment and Forests, highlighted Sinha's work in the Rajya Sabha on 8 March 2011 stating, "..one of the leading authorities on dolphin is a Professor. His name is R.K. Sinha, popularly called 'Dolphin Sinha.' With the help of people like him, we are trying to bring back the Gangetic dolphin which is a unique heritage resource for India." Montek Singh Ahluwalia, Deputy Chairman, Planning Commission of India attended dolphin watches in Patna in 2011 and 2012. His enthusiasm for Sinha's conservation efforts led him to establish the National Dolphin Research Center in Patna, now in progress.
