Whale Week - Posers

There are two types of whales. The kick-ass baleen mouthed kind and the also-kick-ass toothed kind. Baleen is a sieve-like structure in the mouth of certain whales. They use this keratin-based structure to filter tiny, microscopic plankton from the water. Yes, the largest creatures on Earth stay alive by eating some of the tiniest. Toothed whales have rows of teeth. They're used for biting stuff. Like fish and squids. Also, they can use echolocation.

But what about, say...killer whales? I've got news - that's not a whale. Yeah, you heard me. Free Willy?

So never mistake a killer whale for a type of whale again. As for dolphins...*sigh*
