This is a clip from BBC’s Blue Planet II featuring Sir David Attenborough narrating the action as a cuttlefish uses its insane pulsing skin color to hypnotize a crab, then attack it. How quickly its color changes is wild, there’s no question it’s an alien. Admittedly, I felt like I may have been hypnotized too. Where am I, and why did I take my shirt off? “I don’t like the taste of shirt.” I was afraid of that. Just make it quick!
