Answer:
Although penguins look clumsy on land<em>(</em><em><u>, they)</u></em> are graceful in the water. Their bodies are perfectly suited for swimming and diving. They are streamlined torpedo shape. Their wings are shaped like flippers<em>(</em><em><u>; penguins)</u></em>use them to propel themselves through the water at speeds up to 30 miles per hour <em>(</em><em><u>and use)</u></em> their webbed feet to steer. Most penguins can even swim like porpoises<em>(</em><em><u>, leaping)</u></em><em> </em>out of the water to breathe and then diving back in with one graceful motion. Penguins frequently need to dive deep to catch prey(<em><u>, sometimes</u></em><u>) </u>descending to depths of over a thousand feet. The water pressure can be great enough to collapse the lungs (<em><u>but</u></em><u>) </u>penguins have special air chambers in their bodies. When a penguin dives, the chambers squeeze,<u> </u><em><u>(and)</u></em> air is forced into the lungs. The extra air keeps the lungs from collapsing. The chilly waters that penguins prefer would be too cold for most birds (<em><u>but</u></em><u>) </u>penguins are insulated by waterproof feathers and a thick layer of fat. Penguins more than make up for being awkward on land (<em><u>by</u></em><u>)</u> being perfectly suited for the water.
