Octopuses, otherwise known as part of the class, Cephalopods, are highly intelligent creatures of the sea. Some 300 species of which that inhabit water around the world can change various colors and textures and camouflage, squirt out a poisonous substance, and have a force greater than their own total body weight. Their brains are about the same size of their body weight. Different people have different opinions and views on what intelligence is and how someone or something can take in information. One example of how an octopus is smart is that they play around. Like normal intelligent animals would do, they do this also. You can put them in a boring situation with boring items and they would "play" with the objects surrounding them. They gave them and empty tank and a pill bottle and waited to see what the result would be. The octopus ended up shooting a stream of water at the pill bottle after the fourth time causing it to go over a water jet and then back to them. Octopuses know after a certain amount of time and thinking of what to do and how to entertain themselves when it comes to simple and boring things. Octopuses also have personalities like any other living thing. They put them in three situations that are common to them: alerting (opening up the top of the tank), threatening (touching them with a test tube brush), and feeding (they were given a crab to munch.). They found there are three dimensions: activity, reactivity, and avoidance. This is what humans are also known to do. Avoidance is exactly like how humans are when they are avoiding an awkward situation and don't want anything to do with it; being shy. Activity is if you are very active or passive which is just like how humans interact with either body language either "lazy" or active. Reactivity is being really emotional or unimpressed or not bothered. Humans can possess either qualities or just one.
