After being born in San Antonio, Kayla's mother, who is now deceased, was moved to Orlando, Florida, after the pair spent a little less than two and a half years together. SeaWorld has since moved Kayla all over the country - to Ohio and Florida and back to Texas. Her own calf, Halyn, who died at only 2-years old, was torn away from her almost immediately after birth because Kayla, who didn't grow up in a pod with her family, rejected her, likely because she never had the chance to learn to care for a calf.
Splash was taken from his mother when he was 2-years old and moved from Marineland to SeaWorld San Diego. Some allege that Splash died from gastrointestinal complications that may have resulted from his consumption of large quantities of sand that came through his tank's filtration system, something trainers noted that he often ate. This unnatural fixation potentially developed as a result of the stress of perpetual confinement and boredom.
Sumar was raised by surrogate mothers after his own mother, Taima, attacked him when he was 6-months old during a live show at SeaWorld Orlando, likely because she had never learned to care for calves properly, as she would have in the wild. Before his death at the age of 12, Sumar's dorsal fin had curled, a phenomenon rarely seen in the wild but which is commonplace among male orcas held in captivity.
Taku and his mother spent 13 years together at SeaWorld Orlando before he was shipped to SeaWorld San Antonio, where he died 11 months later. Before separating Taku from his mother, SeaWorld allowed them to breed with each other - meaning that Taku's daughter was also his sister.
