The Bahamas, officially the Commonwealth of The Bahamas, is a country in North America. It is an island country within the Lucayan Archipelago of the West Indies in the Atlantic Ocean. It contains 97% of the Lucayan Archipelago's land area and 88% of its population. The archipelagic state consists of more than 3,000 islands, cays, and islets in the Atlantic Ocean, and is located north of Cuba and northwest of the island of Hispaniola and the Turks and Caicos Islands, southeast of the U.S. state of Florida, and east of the Florida Keys. The capital is Nassau on the island of New Providence. The Royal Bahamas Defence Force describes The Bahamas' territory as encompassing 470,000 km2 (180,000 sq mi) of ocean space.
The Bahamas are a group of about 700 islands and cays in the western Atlantic Ocean, of which only between 30 and 40 are inhabited. The largest of the islands is Andros Island, located north of Cuba and 200 kilometres southeast of Florida. The Bimini islands are to its northwest. To the North is the island of Grand Bahama, home to the second-largest city in the country, Freeport. The island of Great Abaco is to its east. In the far south is the island of Great Inagua, the second-largest island in the country. Other notable islands include Eleuthera, Cat Island, San Salvador Island, Acklins, Crooked Island, and Mayaguana. Nassau is the capital and largest city, located on New Providence. The islands have a tropical savannah climate, moderated by the Gulf Stream. The total size is 13,878 km2 (5,358 sq mi). Due to the many widespread islands it has the 41st largest Exclusive Economic Zone of 654,715 km2 (252,787 sq mi).
Andros Island is an archipelago within The Bahamas, the largest of the Bahamian Islands. Politically considered a single island, Andros in total has an area greater than all the other 700 Bahamian islands combined. The land area of Andros consists of hundreds of small islets and cays connected by mangrove estuaries and tidal swamplands, together with three major islands: North Andros, Mangrove Cay, and South Andros. The three main islands are separated by bights, estuaries that trifurcate the island from east to west. It is 167 kilometres (104 mi) long by 64 km (40 mi) wide at the widest point.
Cat Island is located in central Bahamas, and is one of its districts. Cat Island also has the nation's highest point, Mount Alvernia. It rises to 63 metres (207 ft) and is topped by a monastery called The Hermitage. This assembly of buildings was erected by the Franciscan "Brother Jerome".
In Caribbean folklore, the Lusca is a name given to a sea monster said to exist in the region of the blue holes nearby Andros, an island in the Bahamas.
A blue hole is a large marine cavern or sinkhole, which is open to the surface and has developed in a bank or island composed of a carbonate bedrock. Blue holes typically contain tidally influenced water of fresh, marine, or mixed chemistry. They extend below sea level for most of their depth and may provide access to submerged cave passages. Well-known examples are the Dragon Hole and, in the Caribbean, the Great Blue Hole and Dean's Blue Hole.
The Bahama Banks are the submerged carbonate platforms that make up much of the Bahama Archipelago. The term is usually applied in referring to either the Great Bahama Bank around Andros Island, or the Little Bahama Bank of Grand Bahama Island and Great Abaco, which are the largest of the platforms, and the Cay Sal Bank north of Cuba. The islands of these banks are politically part of the Bahamas. Other banks are the three banks of the Turks and Caicos Islands, namely the Caicos Bank of the Caicos Islands, the bank of the Turks Islands, and wholly submerged Mouchoir Bank. Farther southeast are the equally wholly submerged Silver Bank and Navidad Bank north of the Dominican Republic.
