Cover Description: This Alaskan brown bear is catching a migrating salmon. This species of bear is the largest carnivore in Alaska, growing up to 9 feet tall and weighing up to 1,700 pounds. All Alaskan salmon hatch in freshwater, migrate to the sea, and then eventually return to where they hatched to reproduce.
