The spinner dolphin (''Stenella longirostris'') is a small dolphin found in off-shore tropical waters around the world. It is famous for its acrobatic displays in which it spins along its longitudinal axis as it leaps through the air. It is a member of the family Delphinidae of toothed whales. ==Taxonomy== The spinner dolphin is sometimes referred to as the long-snouted dolphin, particularly in older texts, to distinguish it from the similar Clymene dolphin, which is often called the short-snouted spinner dolphin. The species was described by John Edward Gray|John Gray in 1828. The four named subspecies are: *Eastern spinner dolphin (''S. l. orientalis''), from the tropical eastern Pacific. *Central American or Costa Rican spinner dolphin (''S. l. centroamericana''), also found in the tropical eastern Pacific. *Gray's or Hawaiian spinner dolphin (''S. l. longirostris''), from the central Pacific Ocean around Hawaii but represents a mixture of broadly similar subtypes found worldwide. *Dwarf spinner dolphin (''S. l. roseiventris''), first found in the Gulf of Thailand. The species, though, displays greater variety than these subspecies might indicate. A hybrid form characterized by its white belly inhabits the eastern Pacific. Other less distinct groupings inhabit other oceans. The zoology comes from the Latin term for long-beaked. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「spinner dolphin」の詳細全文を読む スポンサード リンク
