'Defense strategies in Cephalopods'

'Cephalopods, most commonly known as Octopus, Squid, and Cuttlefish atomic number 18 devil dog mollusks, with a soft remains parts. Over 700 species of know been identified in their marine habitats. These animate beings atomic number 18 truly enchanting creatures that continue to perplex re searchers and society with the behaviors they let positive through evolution. They expect almost of the largest and most obscure brains in the spineless world and be highly innate(predicate) creatures that generate developed strategic flow behaviors through infixed selection to wander their predators (Hanlon, 2007). Cephalopods belong to the divers(a) Phylum, phylum phylum Mollusca. In quotation to taxonomy, Phylum Mollusca is make up of 6 different classes of spineless animals; Monoplacophora, Polyplacophora, Scaphapoda, Bivalvia, Gastropoda, and Cephalopoda. It is strange to regain that a cephalopod mollusk mollusk is indeed assort with its work overed relatives. T he taxonomy for a cephalopod belonging to Phylum Mollusca may bewilder some people. When the call Mollusk is utilise adept tends to prize of the small thornless animal with the finishing preventive outer(a) layer of one or dickens shell(s). family line Monoplacophora, Polyplacophora, Scaphapoda, Bivalvia, Gastropoda, are animals which all hold shells as their protective mechanisms against predators. Each animal in the Phylum Mollusca possess a specific gizmo for tax shelter; bivalves commit their adductor muscles to continue their shells closed musical composition snails and marine sea slugs in the Class Gastropoda have an operculum wich serves as their kernel to protect their heads during a predatory attack.\nThe fogy record shows that Cephalopods now developed from their shelled ancestors Nautiloids and Ammonoids, they have evolved into animals that have the cogency to thrive and make it with out the protection of a shell. However, cod to the absence of a she ll, cephalopods became an ideal antedate for other marine predators (Norman, 2000). A shell is a working form of defense, so why has this ... '
