Earthworms have blood and it is enclosed in a network of tubes much like the blood system of mammals. It is red because it contains the oxygen carrying pigment hemoglobin. Unlike mammals, where the hemoglobin is inside red blood cells, earthworm hemoglobin is just mixed in the liquid of the blood, commonly called hemolymph.
Earthworms pump their blood around the body with the help of 5 specialized blood vessels that contract and expand. They are the worm's hearts.
