We have a single strong heart pumping blood all through our whole body. 

Most different well-evolved creatures and animals have a solitary heart that flows oxygen and supplements all through the body. 

This multitude of single hearts probably won't appear to be identical, yet they take care of business.

How many hearts do octopus have? Now meet the cephalopods — the squid, octopuses, and cuttlefish (additionally nautiloids, yet we'll come to them later) living in the ocean. 

They weren't content with only one heart, so they proceeded to advance themselves three. 

Their three hearts together pump blood all through their adaptable and for the most part boneless body to supply oxygen.
