Baby Sea Turtles Found to Make Noise to Coordinate Hatching

If you’ve ever witnessed a sea turtle nest hatch, you’ve probably noticed that it seems like these reptiles emerge from their nests in silence. Scientists have long assumed that too, but a new study adds to a growing body of literature that finds that baby sea turtles can in fact make noise—and this communication is key to a successful hatching process.
In a recent study published in Chelonian Conservation and Biology, researchers examined leatherback sea turtle nests, and found that the hatchlings and embryos made multiple noises and sounds—indicating they’re communicating with each other in the days before they hatch. The scientists recorded more than 300 different sounds, and classified them into four unique sound types: chirps, grunts, and two “complex hybrid tones,” according to the Smithsonian…
