According to Graham Henry, the campaign coordinator for Sea Shepherd, people probably don't know what the dolphins go through before they pay to swim with them. "I don't think the tourists are provided with information as to how the dolphins are obtained during the drive hunts and captive selection process," Henry told The Dodo. "This is just my opinion, but I really don't think the tourists are told."
To make matters worse, the dolphins live in substandard conditions at the Dolphin Base. They're kept in tiny sea pens that are about 26 feet by 26 feet, prohibiting them from traveling the long distances they're accustomed to in the open ocean. Dolphins are social creatures, but they're often kept in isolation from others, and given very little enrichment or stimulation.
"It's unnatural," Henry said. "It causes the dolphins to be depressed, frustrated and stressed."
