Galápagos sea lions are as playful as any of their pinniped relatives, and this picture proves it. Puffer fish are some of their favorite toys: they bother the fish until it bloats up in self-defense, then toss it back and forth like a ball. Captive sea lions who play with beach balls are emulating this behavior.
This photo was taken on Sombrero Chino/China Hat island, a heavily protected isle in the Galápagos.
