Each summer, massive groups of sperm whales travel through warm waters to the icy ocean of the Arctic and Antarctive to feed on the swarms of fish that group there. In the fall, the massive creatures travel back to toward the equator to breed. Driven by the need to lead these largest toothed migratory mammals interact with dolphins, swarming bait balls, and other whales along the way. This level 3 reader Great Migrations: Whales follows their perilous, but amazing journey, in a fun and informative fashion.
