"Captive orcas have committed incest."
In the wild, it's taboo for orcas to mate with their immediate family. Though they often spend their lives together, the males travel outside the pod to mate. On the rare occasions when orca relatives are are kept together in captivity, the result is unnatural.
"For me, this is the most horrible difference between wild and captive whales," Rose says. "It shows just how abnormal they are. Captive sons never learn they shouldn't mate with their mother. And captive mothers never learn they shouldn't let them."
Captive females are bred as children.
"Young females are bred far too early, when they're physically but not socially or emotionally ready," Rose says. "They are children having children ... and so they sometimes reject their calves."
