The Clymene Dolphin is found only in the tropical and subtropical Atlantic Ocean, including the Caribbean Sea and Gulf of Mexico (Jefferson et al. 1995). This species has a notable warm-water preference, although there are records as far north as New Jersey on the U.S. east coast and as far south as southern Brazil (Zerbini and Kotas 1998). The limits on the West African coast are not well known, but extend from at least the equator north to Mauritania. The Clymene Dolphin is not known to enter the Mediterranean Sea (Perrin and Mead 1994, Jefferson and Curry 2003, Fertl et al. 2003).
