胚胎海龟的质量随孵化时间的增加可用指数增长方程来描述，呈S形。将生长方程与胚胎数据进行拟合所需的系数在物种之间和物种内都有所不同，这取决于海龟种群的质量和孵化时间。当成群结队的卵在可以控制气体交换的人工巢中孵化时，生长速度和孵化成功率与巢气体交换有关。最大的生长速度(孵化-60天)和孵化成功发生在与在自然巢中测量的非常相似的呼吸环境中。由于呼吸气体在巢和大气之间的移动受到限制，胚胎的生长速度和卵孵化的成功率都会降低。
The increase in mass of embryonic sea turtles (Chelonia mydas, Caretta caretta) with incubation time can be described by a decaying exponential growth equation and appears sigmoidal in pattern. The coefficients required to fit the growth equation to the embryonic data vary among and within species depending on the mass and incubation times of the sea turtle population. When groups of eggs are incubated in artificial nests where gas exchange can be manipulated, rates of growth and hatching success are related to nest gas exchange. Maximal rates of growth (incubation - 60 days) and hatching success occur in a respiratory environment quite similar to that measured in natural nests. As movement of respiratory gases between the nest and the atmosphere is limited, embryonic rates of growth and egg hatching success are reduced.
