The unusual fact that you may not be aware of is that several different animal species in the world have multiple hearts functioning in their bodies.
This blue-blood creature has three hearts. Two peripheral hearts, or Gill’s hearts that are used to pump blood through the gills. Besides, there is a central heart to supply blood to the rest of the body.
Like its body, Earthworm has a tubular heart that runs through. Very different from humans, they have several muscular segments called aortic arches or hearts, that help circulate blood throughout the body.

Like Octopus and Hagfish, Squid also has a unique cardiovascular arrangement, and a set of three hearts — two pump blood to the gills, while the third is responsible for the whole body.
