Breathe and Blow
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
for 3 to 5 minutes. Gray whales don't follow that breathing pattern while in the lagoons.
