The sea lions that hang out on the Elliott Bay buoys enjoyed the sunshine today and entertained walkers with their high-flying acrobatics. These athletic maneuvers, called porpoising, are used to elude predators such as orcas and sharks, but also seemed to just be plain fun on this gorgeous day. Sea lions hone their skills at these movements through play. The buoy was packed with male sea lions, barking loudly as they jostled for a resting place.
