SeaWorld has previously agreed not to take any more wild-caught cetaceans, meaning this should be its last generation of killer whales. The orcas it already owns — including one that became pregnant last year — will continue living at SeaWorld, likely for decades. The company has 29 orcas, seven of them in Orlando. Six of those whales are in a Spanish theme park. Average life spans have been debated but SeaWorld has several killer whales in their 30s and one that is close to 50.
