^Not the animal kingdom, life in general. We're foolish if we think we're the only ones in the universe. Look at the different types of life forms living in all kinds of environments here on earth and our planet is hardly a spec in the scope of the universe.
On topic with OP's video it is amazing how quickly cephalopods can change their camouflage. Life is incredible.
lots of cool info there.
As a kid, we had a 175 gal saltwater tank with coral and other marine life. At one point we did have a octopus. They are pretty cool, untill we came home and found it in the other room...not in the tank. Same thing happened to a snowflake eel we had for awhile
Always like seeing that video. There's also a squid called the "Vampire Squid" like that too. Doesn't cloak exactly like that octopus but it's still cool.
