In the fascinating adaptation of animals, including the presence of multiple hearts, the creativity of nature is obvious. Although most creatures rely on a heart, some have evolved additional hearts to meet unique physiological needs.

Octopus: Three-hearted animal
Octopus is a cephalopod and has three hearts. The heart of both branches pumps blood through the ill for oxygenation, while the heart of the whole body circulates oxygenated blood throughout the body. This arrangement ensures effective oxygen delivery, especially since the octopus blood is rich in copper and viscous, requiring huge pressure to effectively circulate.

Jill’s two branch hearts of oxygenation; a heart with systemic circulation. |

One main systemic heart; three auxiliary hearts help circulation. |

Distribute along the body; the main heart is located in the head area. |
|
horseshoe crab |
1 + Heart sinus |
One pair of main hearts and five pairs of sinus circulating hemolymphs. |

Water ches |
Many pairs |
The paired heart draws blood during feeding through its circulatory system. |
Why are these animals so attentive?
The evolution of multiple hearts allows these animals to adapt to specific environmental challenges:
- Effective oxygenation: Cephalopods like octopus, squid and cuttlefish need specialized systems to oxygenate their dense, copper-rich blood.
- Segmented Circulation: Earth and cockroaches use distributed circulatory systems to maintain blood flow from their slender bodies.
- Survival under harsh conditions: Hag fish and horseshoe crabs rely on assisted circulation mechanisms to survive in hypoxic environments.
These significant adaptations emphasize nature’s creativity in solving physiological challenges. Whether it is a three-hearted octopus or a multi-hearted hag fish, these creatures demonstrate how evolutionary theory tailors biology to meet survival needs.
