Study Notes
Animals with Multiple Hearts
- Some species of cephalopods, a class of marine mollusks (e.g., octopus and squid), possess a complex circulatory system that includes three hearts.
- These hearts have distinct roles in the circulatory process.
- One heart pumps blood through the gills, where it absorbs oxygen.
- Two additional hearts circulate blood throughout the rest of the body.
- This system allows for efficient oxygen uptake and distribution throughout the organism.
- The presence of multiple hearts is a specialized adaptation found in cephalopods, and not present in other groups of animals.
- This physiological adaptation is an example of convergent evolution, as similar solutions have evolved independently in different lineages.
- The circulatory systems of cephalopods are distinctive compared to those of vertebrates and other invertebrates, each having adapted unique solutions to their environment.
