Spinner dolphins have long been known for their teamwork in capturing prey, but a study using high-tech acoustics found their synchronization is even more complex than scientists realized, and likely evolved as a strategy to maximize their energy intake. The study found that dolphins engage in a highly choreographed night-time dance to enclose their prey, and then dart into the circle...
