移动的变温动物可以通过选择环境中特定的温度条件来控制体温，但是胚胎被困在一个不移动的蛋中并且缺乏运动结构被认为缺乏这种能力。我们的实验研究证明，即使是早期阶段的海龟胚胎也会在蛋内移动，以利用小规模的空间热异质性。行为体温调节并不局限于孵化后的生活，而是可能是生活史每个阶段的重要策略。
Mobile ectothermic animals can control their body temperatures by selecting specific thermal conditions in the environment, but embryos-trapped within an immobile egg and lacking locomotor structures-have been assumed to lack that ability. Falsifying that assumption, our experimental studies show that even early stage turtle embryos move within the egg to exploit small-scale spatial thermal heterogeneity. Behavioral thermoregulation is not restricted to posthatching life and instead may be an important tactic in every life-history stage.
