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 have a simple circulatory system that does not require a dedicated heart. Instead, their blood vessels help circulate nutrients and oxygen throughout their bodies. This system is efficient for their small size and basic biological needs.
There are several animals that are said to have blue hearts or blue blood. These are worms, squid, and octopuses. They do not really have blue hearts, it is just the color of the blood in the body before reaching the air.
