marine mammals (whales, dolphins, seals, fur seals, sea lions, walrus, dugongs, manatees, sea otters, and polar bears). Topics of publication on both captive animals and wild marine mammals include aspects of husbandry; behavior; conservation; veterinary medicine; anatomy; physiology; training; population trends; and the effects of pollution,

climate change, and noise. In addition, Aquatic Mammals has the Historical Perspectives feature, which includes essays and high definition DVDs of interviews with prominent marine mammal scientists. The journal also publishes Book Reviews.
