Global Range: (>2,500,000 square km (greater than 1,000,000 square miles)) Tropical, subtropical, and, less often, warm temperate regions of Atlantic, Pacific, and Indian oceans (Leatherwood and Reeves 1983). Costa Rican spinner occurs primarily less than 80 km from shore along the western coast of Central America (7-18 degrees north latitude). Eastern spinner ranges from southwestern coast of Baja California south to the equator and offshore to about 145 degrees west longitude. Whitebelly spinner occupies much of the equatorial Pacific, well offshore, extending south to 20 degrees south latitude off western South America, north to 20 degrees north latitude west of Mexico, and west almost to the Hawaiian Islands. Eastern and whitebelly spinners overlap greatly in range. See Leatherwood and Reeves (1983) and IUCN (1991).
