Right now there are leatherback, loggerhead, and green sea turtles hatching on Florida's Southeast beaches. In addition to collecting samples to ID the sex of loggerhead hatchlings, we are also collecting samples on green and leatherback hatchlings to see if this method can be used on these other species. Stay tuned for pictures of these other two species!

When a sea turtle hatches, it is impossible to identify their sex because they don’t have any sex-specific external characteristics. They don’t have sex chromosomes, instead their sex is determined by the nest incubation temperature. Recently, our lab has shown that the sex of a hatchling can be determined by the presence of a protein in their blood. Our goal is to improve this assay and develop a large-scale method that will allow us to estimate the sex ratio of a given population.
