Cuttlefish are considered “cute” by people who come across them. They are pretty strange to look at, especially with the weird shapes of their pupils, but that’s not why these seemingly docile creatures are on this list, and it’s because of the unique thing they can do with their skin. Experts consider these cool animals the “chameleons” of the sea because of their ability to change the color of their skin and the texture of it. Moreover, they can do all of this in a split second. They use this ability to camouflage themselves from predators or communicate with each other, and they actually have quite an elaborate series of communication elements.
