In this Wednesday, March 27, 2013 photo, an 8-month old female harbor seal, known as Pup 49, swims in a pool at Mystic Aquarium in Mystic, Conn. The pup, rescued in July 2012 on a beach in Plymouth, Mass., was taken to Mystic for treatment, where veterinarians amputated one of her two hind flippers to prevent an infection from spreading throughout her body.
