Cape Domett turtles hatch more males

Scientists says more male flat back turtles are hatching from nests at Cape Domett.

Sex in turtles is determined by sand temperature, and Cape Domett turtles hatch in winter, where increased rainfall is making the sands cooler.

Meanwhile, hotter summers are making beaches in places like Broome hotter, and more females are hatching.

It is hoped the boost in male numbers at Cape Domett will help make up the sex imbalance when they are old enough to mate in several decades’ time.
