Breathe and Blow
Did you know that a gray whale breathes through blowholes on top of its head? A gray whale has a predictable breathing pattern while it's migrating. The whale generally exhales, or blows, 3 to 5 times in 15-30 second intervals. Then it raises its fluke (tail) in a dive and submerges for 3 to 5 minutes. Gray whales don't follow that breathing pattern while in the lagoons. Check out this video clip and you'll see an example!
