SAN DIEGO, CA - NOVEMBER 08: In this handout photo provided by SeaWorld, Cascade, a 29-year-old Atlantic bottlenose dolphin, gave birth to a calf at SeaWorld San Diego on November 5, 2012 in San Diego, California . The 30-pound calf is the 78th dolphin born at the marine-life park. SeaWorld trainers and animal care specialists are monitoring both mom and calf round-the-clock documenting respirations and nursing frequency. Cascade and her calf are doing very well as they swim together and bond. (Photo by Mike Aguilera/SeaWorld San Diego Via Getty Images) less
