The species was beginning to come under threat due to the killing of millions of individuals in tuna purse seines. In the 1980s, the rise of "dolphin-friendly" tuna capture methods saved millions of the species in the eastern Pacific Ocean and it is now one of the most abundant dolphin species in the world. ==Taxonomy== The species was first described by John Gray in 1846. Gray's initial analysis included the Atlantic spotted dolphin in this species. They are now regarded as separate. Both the genus and specific names come from Latin words meaning thin or thinning. Three subspecies are recognised in Rice's 1998 survey of cetacean taxonomy. Two of these have not been formally named. :''S. a. subspecies A'', the off-shore form found in the eastern Pacific :''S. a. subspecies B'', a form found around the Hawaiian Islands :''S. a. graffmani'', a coastal form found from Mexico to Peru :''S. a. attenuata''. 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「Pantropical spotted dolphin」の詳細全文を読む スポンサード リンク
