The Indian Ocean is the third largest of the world's oceanic divisions, covering approximately 20% of the water and 73,560,000 km² in area, of the global oceans on the Earth's surface.[1].Marine mammals, which include seals, whales, dolphins, and walruses, form a diverse group of 128 species that rely on the ocean for their existence.[2].Out of 128 species ,fourth of these may be found in India and adjacent countries.One species belonging to the order Sirenia, namely the dugong, and 30 species of cetaceans, including dolphins, whales and porpoises, are found in the waters of the Indian subcontinent.Marine Mammals of the Indian Ocean form a large group of animals including whales, dolphins, seals and the dugong, also known as the sea cow [3].In size they range from the relatively small Finless Porpoise to the largest animal ever to have lived on Earth, the Blue Whale.
