Super Swimmers
Emperor penguins swimming underwater in Antarctica. These Emperor penguins almost never leave the sea at all. Their streamlined silhouette helps them speed through the water. And to help them dive, they have solid bones, instead of the light hollow skeletons of other birds. A layer of fat keeps them warm. Their adaptations make penguins world-class swimmers.

Jumping Whale
A humpback whale coming out of the water. Since their ancestors first returned to the sea 50 million years ago, whales and their relatives have adapted to the most extreme conditions.

A Dangerous Game
An orca whale hunting seals. They turn the beach into their hunting ground. To score a kill, the orcas put themselves into a situation that could kill them. They’re after young prey – sea lion pups that are just learning to swim in the icy surf. The orcas’ strategy is to hit the beach and grab a pup. Once an orca drags its massive bulk onto the sand, it takes a lot of effort to get back in the water. A beached orca is a dead whale.

Underwater Reptile
The marine iguana looks like a dinosaur, but it’s something relatively new in nature. These are the only lizards that dive in the sea. They live on the rocky shores of the Galapagos Islands. Their ancestors were land iguanas that probably floated over from the South American mainland - 600 miles away. Marine iguanas are vegetarians. Here in the Galapagos, they eat the algae that grows along the shore. An iguana’s flat snout and sharp teeth make it easy to scrape algae off the rocks. A marine iguana can stay submerged for more than half an hour.
