Flippers of the humpback whale can be as long as 15 feet. All whales are very noisy. They moan, groan, squeak and sigh to talk to each other. These underwater sounds can travel great distances. Whale are the loudest animals in the world.
Whales migrate further than any other animal.
Migrating means to move from one area to another. In the warm summer months, whales feast to build up their blubber and other fat reserves. Then, as the weather and water begin to cool when winter approaches, the whales begin their migration to warmer places. They do not stop to eat, but swim almost constantly, stopping only to rest for short periods of time. For example, gray whales spend the winter months, from December into February, in the warm water of the Pacific Ocean near Baja California, Mexico.
