Animal-borne video from a sea turtle reveals novel anti-predator behaviors.

Predation is a primary selection pressure contributing to both the morphological and behavioral adaptations of organisms (Brodie 1983, Lima and Dill 1990). However, studying the anti-predator behaviors of aquatic taxa such as sea turtles is currently limited by the difficulty of observing the natural behaviors of free-ranging individuals at sea (Heithaus et al. 2008).
