St. Martin's Island is a small coral island in the northeastern Bay of Bengal near the mouth of the Cox's Bazar coast of Bangladesh. The island lies southwest of Teknaf Upazila and is the country's southernmost inhabited landmass, noted for its coral formations, seasonal migratory species, and a fishing-dependent local community. It is administratively part of Teknaf Upazila within Cox's Bazar District of Chittagong Division.

Geography and Geology

The island sits in the northeastern Bay of Bengal off the coast of Teknaf, separated from the mainland by a narrow channel near the mouth of the Naaf River and adjacent to maritime boundaries with Myanmar and the Andaman Sea. Geologically, the island comprises Holocene-era coral sand, consolidated limestone-like reef deposits, and tidal flats that reflect influences from the Ganges Delta sediment regime and seasonal monsoon currents governed by the Indian Ocean Dipole and Monsoon of South Asia. Coastal features include intertidal zones, fringing coral collections, and a continuous sand spit linking a smaller eastern islet; these features are shaped by wave action from the Bay of Bengal and episodic cyclonic storms such as Cyclone Sidr and other regional cyclones. The island's low elevation makes it vulnerable to sea-level rise associated with Climate change and regional subsidence.

History

Human use of the island traces to maritime routes in the Bay of Bengal and coastal communities linked to Arakan and Chittagong trading networks. During the colonial era the island fell under administrative patterns connected to Bengal Presidency and later Eastern Bengal and Assam; maritime charts produced by the British Admiralty recorded its reefs and shoals. In the 20th century the island featured in local fisheries and navigation for vessels operating between Chittagong and Rangoon. Following the Partition of India and the creation of Pakistan (1947–1971), and later the independence of Bangladesh in 1971, the island became integrated administratively with Cox's Bazar District under the Government of Bangladesh. Contemporary history includes conservation initiatives influenced by international bodies such as the International Union for Conservation of Nature and regional marine research collaborations with institutions like the University of Chittagong and Bangladesh Marine Fisheries Research Institute.

Ecology and Wildlife

The island is recognized for fringing coral assemblages, seagrass beds, and intertidal ecosystems that support migratory and resident fauna, including reef fish monitored in studies by the Bangladesh Forest Department and international marine biologists from organizations such as IUCN and university marine programs. Notable fauna and flora reported include acroporid and faviid corals, reef fishes similar to those cataloged by the Southeast Asian Fisheries Development Center, shorebirds frequenting the island during migrations along the East Asian–Australasian Flyway, and occasional sightings of marine megafauna such as dugong-like records comparable to those in Gulf of Mannar reports and sea turtles referenced in Convention on International Trade in Endangered Species of Wild Fauna and Flora discussions. Conservation concerns center on coral bleaching events tied to elevated sea surface temperatures during strong El Niño–Southern Oscillation phases, overfishing affecting reef trophic structure as described in regional fisheries literature, and habitat degradation from unregulated tourism noted by environmental assessments by Bangladesh Navy coast patrols and conservation NGOs.

Demographics and Culture

Resident population figures have been reported in national censuses administered by the Bangladesh Bureau of Statistics, with livelihoods traditionally linked to artisanal fisheries and small-scale agriculture influenced by cultural practices of Bengali coastal communities. The island's social fabric reflects connections to nearby settlements such as Teknaf and Cox's Bazar, with religious life centered on local mosques in line with broader Islam in Bangladesh demographics, while cultural exchange occurs through seasonal maritime links to Myanmar and historical ties to Arakanese coastal peoples. Local craftsmanship includes boatbuilding reminiscent of techniques used in Chittagong shipyards and fish processing methods common across the Bay of Bengal littoral.

Economy and Tourism

The island's economy is primarily based on artisanal fisheries, small-scale retail services, and a growing tourism sector that attracts domestic and international visitors interested in beaches, coral viewing, and marine biodiversity, similar to tourism patterns found in Cox's Bazar and Saint Martin (French) destinations. Tourism pressure, especially during peak seasons, has prompted policy responses from the Bangladesh Tourism Board and local administration in Teknaf Upazila to regulate day trips, lodging, and environmental impacts. Fisheries are monitored by the Bangladesh Fisheries Development Corporation and local cooperatives, with concerns about stock sustainability paralleling regional challenges addressed in reports by the Food and Agriculture Organization.

Transportation and Access

Access is primarily by small boats and launches operating from ports and landings at Teknaf and nearby launch points used for coastal transit in Cox's Bazar District. Seasonal weather patterns driven by the Southwest Monsoon and occasional cyclones influence navigability, with the Bangladesh Coast Guard and Bangladesh Navy providing maritime safety and occasional search-and-rescue operations. Infrastructure on the island includes basic jetties, walkways, and limited guesthouses; proposals for improved docking and regulated transport services have been discussed by regional planners from Chittagong Division authorities and national ministries concerned with coastal development.
