The word octopus comes from a Greek word that means “eight octo foot pus.” Octopuses have hard beaks, like a parrot’s beak. They use their beaks to break into and eat hard-shelled animals like crabs.
Octopuses are smart creatures. They are good at traveling through mazes, and have very good vision as well as a strong sense of touch. They have three hearts, two of them pump blood through their two gills, and one pumps blood through the rest of their bodies.
