I like swimming in the mediterranean and looking at the fish. I get really happy when I spot an octopus. They are hard to spot. They can probably see with their skin! That’s how they manage to completely blend in with their surroundings. When I swim I don’t blend in with my surroundings. The octopus spots me first, that is for sure.
