Some people have acted like it's sily of me to feel uncomfortable swimming in the ocean. They may be tourists but I'm food and I know it.

Nah, that's a hunting technique that Killer Whales use. They drive their prey closer and closer towards the beach, which gives it less room to maneuver. They actually practice from a very young age at “unbeaching” themselves. You can see whatever it ate slip into its mouth at about 0:40. Looked like a seal.

i think that this whale is actually just beached….
