'Cephalopods, most commonly known as Octopus, Squid, and Cuttlefish atomic number 18 leatherneck mollusks, with a soft dead body parts. Over 700 species of ready been identified in their marine habitats. These brutes ar truly enthralling creatures that continue to flummox reoceanrchers and society with the behaviors they set out certain through with(predicate) evolution.
