Which animal has 8 hearts?
One type of animal that has eight hearts is the octopus. Although the octopus is often thought of as having just one heart, it actually has a complex circulatory system that includes three hearts and five branchial hearts.
Two of the three hearts pump blood around the body, while the third heart is dedicated solely to the animal’s gills. These five branchial hearts pump oxygen-rich blood towards the gills, where it is then exchanged with carbon dioxide-rich blood.
This means that the octopus can receive oxygen when its respiratory system is engaged in the process of respiration. Quite impressive!.
Is there an animal with 4 hearts?
No, there are no animals on earth with four hearts. There are some creatures that have more than one heart, such as certain types of octopuses, but none of them have four. The octopus has three hearts.
Two of them push blood to the gills and the third circulates it around the body. Another creature that has multiple hearts is the tardigrade, also known as the water bear. This creature has eight tubular hearts running down its body that pump hemolymph, a colorless fluid similar to blood, around the body.
