If you've seen the documentary Blackfish, you know why it's so surprising.
SeaWorld Orlando is where the orca Tilikum is kept. He was caught in the wild about 30 years ago and has since been involved in three human deaths including that of SeaWorld trainer Dawn Brancheau right there in Orlando. The orcas at SeaWorld's theme parks (if they cared about animals, they would be non-profit sanctuaries or rehabilitation centers) are kept in tiny tanks where they become stressed, lack proper exercise, and are a risk to other animals and people.
SeaWorld also has also been fighting to import even more wild animals, beluga whales, into the United States, so it can make money off their captivity. And they're fighting to get trainers back into the water for performances even though they've been fined tens of thousands of dollars because it's already been proven to be a huge risk to the workers.
