Saint Martin Island () is a small island (area only 3 km2) in the northeastern part of the Bay of Bengal, about 9 km south of the tip of the Cox's Bazar-Teknaf peninsula, and forming the southernmost part of Bangladesh. There is a small adjoining island that is separated at high tide, called Chera Dwip. It is about west of the northwest coast of Myanmar, at the mouth of the Naf River. History and description Millennia ago, the island used to be an extension of the Teknaf peninsula, but at a later time some portion of this peninsula got submerged and thus the southernmost part of the aforementioned peninsula became an island, and was disconnected from the Bangladesh mainland. The first settlement started 250 years ago, in 18th century, by Arabian merchants who named the island 'Jazira'. During British occupation the island was named after the then Deputy Commissioner of Chittagong Mr. Martin as St. Martin Island. Likely because one or more of the Arabs were Saint and whose name could not be identified. Local names of the island are "Narikel jinjira" which means 'Coconut Island', and "Daruchini Dwip" which means "Cinnamon island". It is the only coral island in Bangladesh. Administration The island makes up the Saint Martin's Union Parishad. It has 9 villages/areas: Paschim Para (Western Neighbourhood) Deil Para Uttar Para (Northern Neighbourhood) Majher Para (Middle Neighbourhood) Purba Para (Eastern Neighbourhood) Konar Para (Edge Neighbourhood) Nazrul Para (Neighbourhood of Nazrul) Golachipa (literally "narrow neck") Dakkhin Para (Southern Neighbourhood) Inhabitants Most of the island's approximately 3,700 inhabitants live primarily from fishing. The other staple crops are rice and coconut. Being very common on the island, algae are collected, dried, and exported to Myanmar. Between October and April, the fishermen from neighboring areas bring their caught fishes to the island's temporary wholesale market. However, imports of chicken, meat and other foods come in from the mainland Bangladesh and Myanmar. As the centre and the south are mainly farmland and makeshift huts, most of the permanent structures are around the far north. During the rainy season, because of the dangerous conditions on the Bay of Bengal, the inhabitants have no scope to go to the mainland (Teknaf) and their life can become dangerous. There is a hospital on the island, but in the past there has often been no doctor. Biological diversity and bioprospecting potential Research by the Bangladesh Department of
