Do octopus have organs

Yes, octopuses have organs, including a heart, gills, and a complex nervous system. They possess three hearts: two pump blood to the gills for oxygenation, while the third pumps it to the rest of the body. Additionally, octopuses have specialized organs such as a beak for feeding and a siphon for locomotion and expelling water. Their unique physiology supports their adaptability in various marine environments.
