A reader recently asked us, “Do worms have 3 hearts?” There are many different types of worms, and he didn’t specify which worm he was curious about. We assume he is inquiring about earthworms, but if he is curious about another type of worm we encourage him to write to us again!
Earthworms actually have 5 hearts, but this organ and the worm’s circulatory system are much simpler than ours. Each of these 5 hearts pumps blood through blood vessels to all of the body parts, just like in humans.
