^h English (en)	Most fish are exclusively cold-blooded or [[ectothermic]]. However, the [[Scombroidei]] are [[warm-blooded]] (endothermic), including the [[billfish]]es and tunas. The [[Lampris guttatus\|opah]], a [[lampriform]], uses whole-body endothermy, generating heat with its swimming muscles to warm its body while countercurrent exchange minimizes heat loss. Among the cartilaginous fishes, sharks of the families [[Lamnidae]] (such as the great white shark) and [[Alopiidae]] (thresher sharks) are endothermic. The degree of endothermy varies from the billfishes, which warm only their eyes and brain, to the [[bluefin tuna]] and the [[porbeagle shark]], which maintain body temperatures more than {{convert\|20\|C}} above the ambient water.
^h Japanese (ja)	ほとんどの魚は完全に変温動物すなわち[[ectothermic/ja\|外温性]]である。しかし、[[Scombroidei/ja\|サバ亜目]]には[[warm-blooded/ja\|恒温性]]（内温性）の魚が含まれ、カジキ類やマグロがそれにあたる。[[Lampris guttatus/ja\|アカマンボウ]]は[[lampriform/ja\|マンボウ目]]の魚で、全身恒温性をもち、遊泳筋で熱を発生させて体を温め、対向流交換によって熱損失を最小化する。軟骨魚類の中では、[[Lamnidae/ja\|ネズミザメ科]]（ホホジロザメなど）や[[Alopiidae/ja\|オナガザメ科]]（オナガザメ）が恒温性を示す。恒温性の程度は、目と脳のみを温めるカジキ類から、環境水温より20℃以上高い体温を維持する[[bluefin tuna/ja\|クロマグロ]]や[[porbeagle shark/ja\|ネズミザメ]]まで様々である。
