Bone up on your knowledge of whales, dolphins, and porpoises at, a collection of backgrounders on all 81 known species of cetaceans. The streamlined accounts by a British writer and whale aficionado deliver the basics on appearance, classification, behavior, food, and habitat. You can investigate the lives of species such as the bottle-nosed dolphin and the beluga whale, a vocal inhabitant of the arctic seas. Centuries of slaughter have nearly extirpated some species, and the site is chock-full of grim statistics. For instance, blue whale numbers have fallen 99% in the last century, to only 3000 animals, and experts fear that populations of some protected species, such as the northern right whale, may never recover.
