  The geography and climate in the Caribbean region varies: Some islands in the region have relatively flat terrain of non-volcanic origin. These islands include Aruba (possessing only minor volcanic features), Curaçao, Barbados, Bonaire, the Cayman Islands, Saint Croix, the Bahamas, and Antigua. Others possess rugged towering mountain-ranges like the islands of Saint Martin, Cuba, Hispaniola, Puerto Rico, Jamaica, Dominica, Montserrat, Saba, Sint Eustatius, Saint Kitts, Saint Lucia, Saint Thomas, Saint John, Tortola, Grenada, Saint Vincent, Guadeloupe, Martinique and Trinidad and Tobago.
  
  Definitions of the terms Greater Antilles and Lesser Antilles often vary. The Virgin Islands as part of the Puerto Rican bank are sometimes included with the Greater Antilles. The term Lesser Antilles is often used to define an island arc that includes Grenada but excludes Trinidad and Tobago and the Leeward Antilles.
  
  The waters of the Caribbean Sea host large, migratory schools of fish, turtles, and coral reef formations. The Puerto Rico Trench, located on the fringe of the Atlantic Ocean and Caribbean Sea just to the north of the island of Puerto Rico, is the deepest point in all of the Atlantic Ocean.
  
  The region sits in the line of several major shipping routes with the Panama Canal connecting the western Caribbean Sea with the Pacific Ocean.
