Why dont we just breed them in captivity or collect the eggs in a hatchery?
One of the most interesting aspects of sea turtle biology is that the sex of developing embryos is determined by temperature! Female turtles are produced in warmer nests, males in cooler locations, a temperature of about 30 C produces roughly equal numbers of males and females. Careful round the clock monitoring is therefore necessary to ensure that the natural gender balance is maintained as a population of all males or all females would be unable to reproduce.
