Panga is the common South African name for ''Pterogymnus laniarius'', a small, ocean-dwelling fish, native to the southeast Atlantic Ocean and southwest Indian Ocean. Alternatively called "torpedo scads", they are cold-blooded with white flesh. Their scales are generally pink in color with whitish underbelly and blue-green stripes running laterally along their sides. Over the course of its life, a panga will undergo periodic sex-changes with as much as 30% of the population being hermaphroditic at a time. Despite the presence of both sex organs, it is thought unlikely that both are simultaneously active. Panga are slow to reach sexual maturity, with a minimum population doubling time of 4.5–14 years. In other countries, the name ''panga'' may refer to a different species. In Indonesia, it refers to ''Megalaspis cordyla'', in Spain, France, the Netherlands and Poland it refers to ''Pangasius hypophthalmus'', and in Kenya it refers to ''Trichiurus lepturus''. ==References== * * 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「panga」の詳細全文を読む スポンサード リンク
