Recently, a female orca died that was thought to be at least 90 years old and maybe as old as 105 (she was sighted as early as the 1930's). While it is true that killer whales live longer in the wild, Sea World was definitely doing everything that they could to keep their captive whales as happy as possible. The capturing of killer whales in the wild seems fairly wrong but breeding captive whales seemed okay.
I am sad that Sea World is discontinuing the whale shows as that was the only way that most people could ever see one that close. I just really disliked the fact that legislation went into place as a kneejerk reaction to a fluff piece of "journalism".
Per Indian legends, killer whales are the spirits of marine hunters. When the whale was killed or died, it was reborn as a human. Somewhere out there, a kid is being born that will have a mohawk that leans to one side.
