SeaWorld San Antonio welcomed seven more beluga whales on Tuesday, the latest development in the international effort to relocate dozens of the mammals from a shuttered Canadian theme park. "We are so happy that all went well and the second transport of this huge rescue effort is complete," said Steve Aibel, SeaWorld San Antonio's vice president of zoological operations. The seven whales joined Frankie and Bertie Botts, who completed the same nearly 2,000-mile journey from Niagara Falls to San Antonio during the first relocation last month. Four other whales from that transport were brought to the Shedd Aquarium in Chicago. The two males are adjusting well, according to caretakers at SeaWorld, and are slowly being introduced to the existing whales at the park.
