They do, otherwise, how would they pump blood? They have 5 hearts, according to wikipedia and several science websites. (You can look it up if you need proof.)
5, like all worms.
No, worms do not have 5 hearts. Most worms have a simple circulatory system with vessels that pump blood, but they typically have a single or double main pumping vessel called an aortic arch that acts like a heart.
It was speculated that some dinosaurs may have had two hearts to help pump their blood around. Earth worms supposedly have six hearts.
Worms don't have five hearts; they typically have a simple circulatory system with one main "heart" called an aortic arch that pumps blood throughout their body. The misunderstanding may have arisen due to the segmented structure of their bodies, with each segment containing a pair of aortic arches that may be mistaken for multiple hearts.
segmented have lines in them and non dont.
Worms have 5 hearts. Worms have an organ that behaves like a heart, an aortic arch, they have five arches.
worms
they are hearts worms
Technically, they don't. There are five objects similar to hearts that are called aortic arches. I'm not positive all types of worms have these aortic arches but this is the most probable answer.
Yes, just not the same design as a Human heart
worms mollusks
