Do leather back need warmth when they hatch?

Leatherback sea turtles do not require warmth when they hatch, as they are ectothermic and rely on ambient temperatures for thermoregulation. The temperature of the sand where the eggs are laid determines the sex of the hatchlings rather than the need for warmth during hatching. Typically, warmer sand produces more females, while cooler sand results in more males. Once hatched, the young turtles must quickly move to the ocean to avoid predators and find suitable conditions.
