The Gulf of Mannar is a large shallow bay forming part of the Laccadive Sea in the Indian Ocean. It lies between the southeastern tip of India and the west coast of Sri Lanka, in the Coromandel Coast region. The chain of low islands and reefs known as Ramsethu, also called Adam 's Bridge, which includes Mannar Island, separates the Gulf of Mannar from Palk Bay, which lies to the north between India and Sri Lanka. The estuaries of Thamirabarani River and Vaipar River of South India and the Malvathu Oya (Malvathu River) of Sri Lanka drain into the Gulf. The dugong (sea cow) is found here.
