The Caribbean Sea[1] is a sea of the North Atlantic Ocean in the tropics of the Western Hemisphere, located south of the Gulf of Mexico and southwest of the Sargasso Sea. It is bounded by the Greater Antilles to the north from Cuba to Puerto Rico, the Lesser Antilles to the east from the Virgin Islands to Trinidad and Tobago, South America to the south from the Venezuelan coastline to the Colombian coastline, and Central America and the Yucatán Peninsula to the west from Panama to Mexico. The geopolitical region centered around the Caribbean Sea, including the numerous islands of the West Indies and adjacent coastal areas in the mainland of the Americas, is known as the Caribbean.
The Caribbean Sea is one of the largest seas on Earth and has an area of about 2,754,000 km2 (1,063,000 sq mi).[2][3] The sea's deepest point is the Cayman Trough, between the Cayman Islands and Jamaica, at 7,686 m (25,217 ft) below sea level. The Caribbean coastline has many gulfs and bays: the Gulf of Gonâve, the Gulf of Venezuela, the Gulf of Darién, Golfo de los Mosquitos, the Gulf of Paria and the Gulf of Honduras.
The Caribbean Sea has the world's second-largest barrier reef, the Mesoamerican Barrier Reef. It runs 1,000 km (620 mi) along the Mexico, Belize, Guatemala, and Honduras[4] coasts.
