GeneralClass 12AllAnswered 27 Mar 2026
Answer
The octopus belongs to phylum Mollusca (or Mollusks), specifically to class Cephalopoda. Mollusca is the second-largest animal phylum, characterized by soft bodies, and many species have shells (though octopuses have lost theirs through evolution). Cephalopods, including octopuses, squids, and cuttlefish, represent the most intelligent and advanced mollusks, featuring complex nervous systems, excellent vision, tentacles with suckers, and remarkable camouflage abilities. Octopuses possess eight arms, three hearts, blue copper-based blood, and sophisticated problem-solving capabilities.
