I can't even begin to describe how irrelevant and incorrect your reply was. I don't think you even understood the terms of the question. Another day on RU-vid.
Killer whales will pretty much attack anything. Their diet depends on their location. They usually hunt whatever species in an abundance or most convenient
Swordfish are known to sleep on the surface sunning themselves. An orca could have a chance in that case only. The swordfishes only known natural enemy is the Mako Shark that kills sunning Swordfish. Mako can attain top speed of 31 mph, Orca 35, Swordfish 61, and sailfish 68 mph.
At the news of Tillicum, the killer whale I was feeling sorry for the whale and writing a statement about my feelings, but now seeing this video I don’t like killer whales anymore. Killer whales are in the same category as dolphins 🐬 and dolphins are very smart creatures so how is it that you are eating your cousins? That’s stupid to me and now I would care less if all killer whales would die
