OLYMPIC SWIMMERS<br />
The world’s fastest underwater birds,<br />
Gentoo penguins can swim up to 20<br />
miles per hour and dive to depths of over<br />
600 feet. Penguins lost the ability to fly<br />
millions of years ago, but their wings<br />
evolved into flippers that help them zip<br />
through the water.<br />
PENGUINS HAVE KNEES<br />
Yes, they do! You just can’t see them<br />
because they’re hidden under all their<br />
fluffy feathers.<br />
UNDERWATER VISION<br />
Penguins have a secondary transparent<br />
eyelid to enable them to see underwater,<br />
meaning their vision is better underwater<br />
than on land. This ‘see-through’ eyelid<br />
helps them to see clearly as they swim<br />
underwater, giving them superior<br />
eyesight to spot prey while hunting.<br />
LET’S STICK TOGETHER<br />
Highly social birds, penguins form<br />
breeding colonies called rookeries, in<br />
which they live in the tens of thousands<br />
and even millions. Many penguins<br />
stay with the same mate for years,<br />
and families stick together, with many<br />
generations using the same nesting<br />
ground. Penguins’ excellent hearing<br />
helps them find each other in a crowd.<br />
