But Rally also saw something even sadder: signs of severe psychological distress.
One orca named Trua, a 9-year-old male, seemed particularly stressed. "He was being held, while I was there, in isolation, completely alone in a back holding tank," Rally told The Dodo. "I don't know the reason why."
Devoid of stimulation, Trua resorted to stereotypic behavior, a sign of captive stress where an animal will repeat meaningless patterns of behavior almost compulsively.
"He would actually approach the wall, then rub his head against the wall as he went down deeper," Rally said. As she watched, Trua would return to the other side of the tank, then swim back and do it again, repeating these strange laps over and over again.
Trua, like many of SeaWorld's orcas, would also float listlessly in the tank - which isn't a natural behavior for wild orcas, who are constantly in motion.
