Washington, UNITED STATES: People watch two 10-month-old sea lion pups, Calli and Summer, as they make their debut at the National Zoo in Washington 03 May 2006. Calli's mother died shortly after giving birth, and Summer's mother abandoned her. They were taken to the Pacific Marine Mammal Center in Laguna Beach, which typically releases rehabilitated pups into the wild. But because these pups were hand-reared, they require human attention and were sent to the National Zoo in March. AFP PHOTO/Nicholas KAMM (Photo credit should read NICHOLAS KAMM/AFP via Getty Images)
