How is it that these animals don’t attack humans, or do they?
Usually ‘mishaps’ with Orca versus human are attributed to wetsuits making humans look like seals. That injury tends to be an orca ramming a surfboard or swimmer.
There was a captive orca who killed a trainer and swam with her body in his mouth and refused to release her until they got him onto a platform and raised him out of the water. However - any captive animal is bound to behave with extremes. Also a captive orca is believed to have breached and landed intentionally on a trainer - again believed to be aggression.
From the reports I’ve seen, most (if not all) killer whale attacks on humans involve captive whales.
I think we stink. At least I hope so. I feel the same way about bears.
