Nearly all of Florida’s loggerhead sea turtle hatchlings are now female

This article discusses how Florida’s loggerhead turtles are female, caused by rising temperatures. This will impact the turtle’s ability to survive.

Every year in Florida, millions of baby sea turtles scramble across the sand from their nests to the ocean. Recently, almost all of these baby turtles have been female.

Wyneken: “When an egg is laid, there’s no x and y chromosome. The sex of the embryo, which means the sex of the hatchling, is determined by the conditions in the nest.”

Jeanette Wyneken of Florida Atlantic University says temperature is the number one factor determining the sex of sea turtles. The hotter the sand, the more likely it is that turtles will be female.
