Most animals don’t live long enough to experience the debilitating effects of old age. But some critters survive for decades, and one in particular, the thick-billed murre, manages to grow old without losing its physical prowess, scientists have found. The research could shed new light on the aging process in other wildlife—and perhaps in primates such as humans. The murre inhabits the far northern reaches of the globe and spends as much time in Arctic waters as it does in the air, diving to depths of 300 feet or more and swim through the sea to hunt fish and other prey. Murres can live 25 years or more, and while scientists from Canada and France discovered that the birds do slow down with age, they don’t lose their diving ability.
