St. Martin's Island in Bangladesh.

 

St. Martin's Island is a small island (area only 8 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 Chhera island. It is about 8 km west of the northwest coast of Myanmar, at the mouth of the Naf River. The first settlement started just 250 years ago by some Arabian sailors who named the island ‘Zajira’. During British occupation the island was named St. Martin Island. The local names of the island are "Narical Gingira", also spelled "Narikel Jinjira/Jinjera", which means 'Coconut Island' in Bengali, and "Daruchini Dip". It is the only coral island in Bangladesh. 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 now a hospital on the island, but in the past there has often been no doctor.

It is possible to walk around the island in a day because it measures only 8 km² (3 sq. mile), shrinking to about 5 km² (2 sq. mi) during high tide. The island exists only because of its coral base, so removal of that coral risks erosion of the beaches. Because of this, St. Martin's has lost roughly 25% of its coral reef in the past seven years.
