Study: Sea turtles create ‘decoy’ nests to protect eggs

Two species of sea turtle, leatherbacks and hawksbills, make ‘decoy nests’ to protect their eggs from predators. When female sea turtles cover their nest chambers in which they lay their eggs, they spend enough time and effort on scattering sand away from the main nest site to reduce the risk of predators discovering their eggs. Interestingly, these two species shared a common ancestor over 100 million years ago.
