Did you know that sea turtle hatchlings don’t have s*x chromosomes like humans?
Instead, the temperature of the nest during incubation helps determine whether hatchlings are male or female—a process known as Temperature-Dependent S*x Determination (TSD). In general, warmer nests tend to produce more females, while cooler nests tend to produce more males.
Many factors influence nest temperatures, including shade, rainfall, nest depth, sand color, and seasonal weather conditions. That’s why protecting nesting beaches is so important for the future of sea turtles.
