A sea turtle's gender, determined by the temperature

Post by sujin007 on Sat Nov 17, 2012 7:41 pm

Sea turtle eggs need to incubate for 45 to 70 days before they hatch. The length of incubation time is affected by the temperature of the sand in which the eggs are laid.

Eggs hatch more quickly if the temperature of the nest is warm. It is same like that in the case of crocodile.. cold for males and warm for females..

So if eggs are laid in a sunny spot and there is limited rain, they may hatch in 45 days, while eggs laid in a shady spot or in cooler weather will take longer to hatch.

Temperature also determines the gender of the hatchling. Cooler temperatures favor the development of more males, and warmer temperatures favor the development of more females. Just think of the potential implications of global warming!!!!!

Interestingly, even the position of the egg in the nest could affect the gender of the hatchling. The center of the nest is warmer, therefore eggs in the center are more likely to hatch females, while eggs on the outside are more likely to hatch males.

As noted by James R. Spotila in Sea Turtles: A Complete Guide to Their Biology, Behavior and Conservation, "Indeed, which way an egg bounces into the nest might determine its sex."
