An Atlantic bottlenose dolphin calf, born at SeaWorld San Diego on June 10, 2009, swims alongside her 11-year-old mother, Malibu. SeaWorld used sex-selection techniques to determine the sex of the calf prior to birth, which enables them to optimally balance their ratio of males and females.
This energetic dolphin calf was born at SeaWorld San Diego on Nov. 28, 2008. Estimated to be a healthy 35 - 40 lbs. and 3 1/2 - 4 feet long, the calf is regularly nursing from her mother, Tobie, and growing steadily.
The female calf was conceived through artificial insemination with sperm that had undergone a gender-selection process. Responsibly managing captive populations is a challenging process, and the ability to choose the sex of a zoo or aquarium baby allows these organizations to maintain a healthy balance.
