A killer whale, 25 feet long and weighing 10,000 pounds, hurls through the waves to stike a seal pup onshore, rocking back to sea with his prey caught in his jaws. This is just one of the heart-pounding experiences that the Kratt brothers bring to this episode, which depicts the coastal creatures of Patagonia. Patrolling the shoreline where arid land meets teeming sea, the Kratts experience the point-of-view of other sea hybrids like the sea lion, penguin, and more.
