Their eyes are large and they have a well-developed brain. Cephalopods are also able to change their coloration to match their surroundings, making them difficult to spot. Cephalopods are an important food source for many animals, including humans. They are also used in research, as they are able to provide insights into the evolutionary history of invertebrates.
