I know you're not asking me but I've seen it!
I've had a couple of octopus encounters in the wild. Out on the west coast in BC and in the Caribbean. Mind blowing.
One out west that had made friends with a woman who was wearing rubber boots similar to mine. My boots were not rubber, they were suede winter boots but were the same brand with similar markings. The octopus was comparing them
It realized we were not the same person and I felt so bad, like I was an imposter. The only reason it revealed itself was bc it had mistaken me for it's friend.
I don't have the heart to ever eat one now, they're just too precious.
