A baleen whale can gulp or skim krill from the water. Humpbacks are baleen whales. They spend three or four summer months off Alaska. During that time, they consume a full year's supply of food. Each whale species has its own variety of sound or song, which can be a click, groan, whistle, creak, burp, cry, scream, or chirp.
Some sounds are inaudible to humans but can be heard by other whales thousands of miles away.
Whales migrate to warmer waters in winter. While on a whale watch a young girl observes a mother whale with its baby swim close by the boat before disappearing into the deep.
