Swimming performance of zebrafish Danio rerio males and females initially reared in four different temperatures was assessed by measuring their relative critical swimming speed after acclimation to a common temperature. Males reared at 31° C achieved higher swimming speeds than females reared at the same temperature. Morphometric measurements indicate differences in body shape between sexes that could account for the difference in swimming speed.
斑马鱼 Danio rerio 雌雄鱼最初在四种不同温度下饲养，然后在适应共同温度后测量其相对临界游泳速度，以此评估其游泳性能。在 31°C 下饲养的雄性鱼比在同一温度下饲养的雌性鱼游得更快。形态测量表明，两性之间的身体形状存在差异，这可能是游泳速度差异的原因。
