成年棱皮龟的体型是最大的海龟的两倍，因此需要更长的时间来冷却。

An adult leatherback is twice the size of the biggest cheloniid sea turtles and will therefore take longer to cool off.

棱皮龟的脚蹼比较薄并且呈刀片状，因此，它们就是棱皮龟身体中有可能被冻住的部位。

Because the flippers are comparatively thin and blade-like, they are the one part of the leatherback that is likely to become chilled.
