Their name was given to the Caribbean Sea, and its Arawakan equivalent is the origin of the English word cannibal. Carib groups of the South American mainland lived in the Guianas, and south to the Amazon River. Some were warriors and they lived in small autonomous settlements, growing cassava and other crops and hunting with blow-gun or bow and arrow. The Caribbean Sea is divided into five submarine basins that are roughly elliptical in shape and separated from one another by submerged ridges and rises. These are the Yucatan, Cayman, Colombian, Venezuelan, and Grenade basins.
Subsurface water enters the Caribbean Sea across tow sills.
These sills are located below the Anegada Passage, which runs between the Virgin Islands and the Lesser Antilles, and the Windward Passage, which runs between Cuba and Hispaniola. Casals was a Spanish cellist, conductor, composer, and admired public figure. He received his first music lessons from his father and studied violin before turning to the cello at the age of 12. By age 21 he had made important modifications in the technique of the cello and was hailed as a master. He toured widely in Europe and the Americas, adding greatly to the popularity of the cello as a solo instrument.
