Which creature has a total of five hearts?
Like humans, most animals have a single heart. However, earthworms don't have just one heart, they have FIVE! The earthworm’s five hearts are segmented and pump blood throughout its body. These hearts pump blood into the dorsal and ventral blood vessels of the earthworm, which delivers nutrients and oxygen throughout their body. The dorsal blood vessels carry blood to the front of the earthworm’s body while the ventral blood vessels are responsible for carrying blood to the back or tail of the earthworm’s body.
