Octopi are well known escape artists from aquaria. Knowing this, I wonder why the octopus exhibit didn’t have any sort of top lid or cover.
EXACTLY....had an acquaintance tell of a friend of his who owned an octopus. Had a fish tank next to the octopus tank...the guy worked nights. He would come home and find all of his fish gone....refill the tank, and then the fish would be gone. Set up a camera....turned out the octopus would climb out of its tank, crawl into the other one, eat the fish, then return to its tank!
