A male named Tilikum came to SeaWorld in January 1992. It wasn't long before Katina was pregnant again. She gave birth to her first son on September 9, 1993; the calf was named Taku. Katina has given birth to seven calves in all, of whom five have been taken from her and shipped other theme parks. Four have died. In the wild, male orcas leave the pod in order to mate. But Taku, Katina’s son, impregnated his mother when he reached sexual maturity. To date, their calf, Nalani, lives with her at SeaWorld Orlando. Taku himself passed away in 2007, several months after being separated from Katina.
