Octopuses have eight arms, but they can use them in different ways. Some of their arms are used to sense their environment, while others are used for manipulating objects or capturing prey. They also have a complex nervous system that allows them to control each arm independently. Octopuses have two hearts and can pump blood through both at once. Their eyesight is not very good, but they do have excellent hearing abilities.
