Whale survives first night at Sea World SAN DIEGO, Jan 12 (UPI) -- Sea World officials say it is too early to tell whether the newborn gray whale that lost its mother has stabilized after surviving its first night at the San Diego theme park. The park's veterinarians say the 5-day-old mammal -- a female with its umbilical cord still attached -- is alert and seems to be doing well in its holding pool. The 1,670-pound (750-kg) baby is being treated for severe dehydration and low blood sugar after being lost in the Pacific Ocean and roaming the harbors of the California coastal cities of Venice and Marina Del Rey. Park veterinarians are feeding the baby a whale milk substitute, fluids and antibiotics. But officials say it will take weeks or months before they can say she has a good prognosis. The whale, which is about 14 feet (4 meters) long, apparently was separated from its herd after being born prematurely during the annual three-month migration from Alaskan waters to the winter feeding grounds in Baja California. It was taken to Sea World after lifeguards and others managed to beach it Saturday. Experts had feared it would die unless it found its mother. Gray whales are federally protected.
