Welcome back to Fun Fact Friday! With hatching season in full swing, we’re sharing one of our favorite sea turtle hatching facts! 🐢
Did you know a sea turtle’s s*x is influenced by the temperature of the sand?🌡
Unlike humans and many other animals, sea turtles don’t have their s*x determined at fertilization. Instead, the temperature of the nest during incubation plays a major role in whether hatchlings develop as male or female.
Cooler sand temperatures are more likely to produce males, while warmer temperatures are more likely to produce females. Since temperatures can vary throughout a nest, one nest can produce a mix of males and females!
North Carolina is especially important for sea turtles. Because our beaches are farther north than many other nesting sites along the East Coast, our cooler temperatures may help produce more male sea turtles. This makes North Carolina an important part of the sea turtle population!
Every nest plays an important role in the future of sea turtle populations.
