SAN DIEGO -- A killer whale was born Tuesday at SeaWorld San Diego.
Kasatka, a 28-year-old killer whale, gave birth on December 21st, 2004 at 9:22 a.m. in Shamu Stadium's main show pool after a little more than two hours of labor.
The healthy-looking calf instinctively swam to the surface to draw its first breath.
The calf is estimated to weigh between 300 and 500 pounds and measures 6 to 7 feet.
The calf's sex hasn't been determined yet. A blood sample will have to be drawn to determine the father.
SeaWorld's zoologists say the mother and baby both appear healthy.
The newborn calf is the fifth born at SeaWorld in San Diego and brings the park's killer whale population to eight.
