Krill

Dinner Time

Penguins eat seafood.  Their main diet is fish, though they'll also eat squid, small shrimplike animals called "krill" (see photo to the right) and crustaceans.

If you look closely at a penguin's bill you'll notice a hook at the end, perfect for grabbing dinner.  They also have backward facing bristles on their tongues that helps slippery seafood from getting away.

Penguins don't live near freshwater -- at least none that isn't frozen.  Instead they drink salt water.  They have a special gland in their bodies that takes the salt out of the water they drink and pushes it out of grooves in their bill.  A handy in-house filtration system!
