Gulf of Mannar Marine National Park

Gulf of Mannar Marine National Park is a protected coastal and marine area in southeastern India, encompassing 21 small islands and their surrounding coral reefs in the Gulf of Mannar along the Tamil Nadu coastline. The park stretches approximately 160 kilometers between Thoothukudi and Dhanushkodi, lying one to ten kilometers offshore in the Indian Ocean. Established as a National Park in 1980 and formally notified in 1986, it serves as the core zone of the larger Gulf of Mannar Biosphere Reserve, which includes a ten-kilometer buffer zone encompassing populated coastal areas. The park protects a remarkable diversity of marine, intertidal, and near-shore habitats, making it one of India's most biologically rich marine protected areas. Its islands vary dramatically in size from less than one hectare to over 130 hectares, and support ecosystems including coral reefs, seagrass beds, mangrove forests, and seaweed communities.
