Back to this week's update.

See Two Blowholes?

As baleen whales, gray whales exhale through TWO slits called blowholes on top of their head. You can see the blowholes on this baby's head. The whale's exhale is called the blow. Blasting out of two blowholes, the blow appears as two misty towers high in the air. If it's not windy, the blow can look heart-shaped. Whales with teeth instead of baleen have only one blowhole. What do you think the blows of those whales look like?
