What causes a sea turtle to be born male or female? - NOAA's …
Research shows that if a turtle's eggs incubate below 27.7° Celsius (81.86° Fahrenheit), the turtle hatchlings will be male. If the eggs incubate above 31° Celsius (88.8° Fahrenheit), however, the hatchlings will be female. Temperatures that fluctuate between the two extremes will produce a mix of male and female baby turtles.

Do sea turtles ever lay eggs underwater? For the eggs to survive and have a chance of hatching, sea turtles must lay their eggs on sandy beaches.

SEA TURTLE LIFE CYCLE – Egg Incubation - NSU
Having a soft shell allows for the egg to withstand the force of being dropped into an egg chamber, which can be anywhere from 2-6 feet deep into the sand depending on the species, without breaking open. The eggs are also porous, meaning that it allows for gases, such as oxygen, and liquids, such as water, to pass freely through the membrane.
