Young (mean mass 735 g) green turtles (Chelonia mydas) were able to swim in a water channel at sustained speeds between 0-14 and 0-35 m.s-1. Oxygen consumption at rest was was 0-07 l.kg-1.h-1; at maximum swimming speed oxygen consumption was 3-4 times greater than at rest for a given individual. In comparison with other animals of the same body mass the cost of transport for the green turtle (0.186lO2.kg-1.km-1) is less than that for flying birds but greater than that for fish. From drag measurements it was calculated that the aerobic efficiency of swimming was between 1 and 10%; the higher efficiencies were found at the higher swimming speeds. Based upon the drag calculations for young turtles, it is estimated that adult turtles making the round-trip breeding migration between Brazil and Ascension Island (4800 km) would require the equivalent of about 21% of their body mass in fat stores to account for the energetic cost of swimming.
体重平均为735克的绿海龟（蠵龟）能够在水道中以0.14至0.35米/秒的持续速度游泳。静止时的耗氧量为0.07升/千克·小时；对于特定个体，最大游泳速度时的耗氧量比静止时大3至4倍。与其他相同体重的动物相比，绿海龟的运输成本（0.186升氧气/千克·千米）低于飞鸟，但高于鱼类。根据阻力测量结果计算得出，游泳的有氧效率在1%至10%之间；游泳速度越高，效率越高。根据幼龟的阻力计算，估计成年海龟在巴西和阿森松岛之间往返进行繁殖洄游（4800千米）时，需要约占其体重21%的脂肪储备来支付游泳的能量成本。
