 And fishing can be dangerous. A southern sea lion. It uses the speed of a breaking wave to catch up with the gentoos. Sea lions normally eat fish. So he is used to catching streamline swimmers. But the gentoos seem more than his match-up at sea. He must change tactics. Perhaps it would be easier in the shallows. But, no, it seems penguins are uncatchable in water. How about on land? The penguin's wings are so powerful for swimming, but of no help when it comes to running. Now surely the sea lion has a chance. But on the beach both are like fish out of water. Rarely do hunter and hunted play their roles with so little skill. The outcome is anyone's guess.
