I don't remember where this was, but this place that had sharks in it that was kind of like an aquarium got octopuses too. They were afraid that if they put the octopuses in a tank with the sharks that the sharks would eat them. So they had to put them in separate tanks. For some reason some of the sharks started to vanish. It puzzled the employees at the aquarium so they set up cameras in the shark's tank. What they saw startled them. The octopuses in the middle of the night were climbing out of their tank and eating the sharks, and going back into their tank before day light. I found this kind of ironic and interesting. THIS IS TRUE. Don't start commenting that it isn't I know it sounds unlikely, but it is true. Personally I didn't really believe at first, but it's pretty cool. Thank you for reading.
