Question

Do any animals have more than one heart? If so, how many?

Cephalopods such as the squid and octopus possess 3 hearts, 2 to pump blood to through each of the gills and the third to pump blood around the body.

Answer 2

some snakes have two p***s'.....

if something has more than one heart their probably not hearts but chambers, like worms.

Answer 3

Animals with closed circulatory systems generally have some sort of heart or hearts.  Vertebrates are the only animals that have what you might consider a "true" heart, a single pump with distinct chambers and reservoirs.

Invertebrates with closed circulatory systems, though, also have pumping structures that are usually referred to as hearts.  Earthworms (and other annelid worms) have five dorsal hearts.  Cephalopods, like octopi and squids, have two gill hearts that pump blood through the gills, and a systemic heart, which pumps blood to the rest of the body.
