Guide to Marine Mammals of Alaska is the only field guide that exclusively covers all 29 marine mammal species of Alaska. Each whale, porpoise, dolphin, seal, sea lion, walrus, sea otter, and polar bear is described and illustrated. Color photos and surface profile drawings show Alaska marine mammals and compare similar species, and color range maps show distribution. Mammal characteristics and descriptions are presented in a format that allows fast, accurate identification at sea. The 80-page, award-winning, richly illustrated book is printed on durable water-resistant paper, and is wire-bound to give years of service outdoors and in the office, classroom, and home.
