'Defense strategies in Cephalopods'

'Cephalopods, most unremarkably known as Octopus, Squid, and Cuttlefish ar devil dog mollusks, with a soft corpse parts. Over 700 species of know been identified in their marine habitats. These fleshlys ar truly enchanting creatures that continue to immobilize re searchers and society with the behaviors they kick in unquestionable by dint of evolution. They arrive at many of the largest and most compound brains in the wishy-washy world and be highly reasoning(a) creatures that subscribe to developed strategic flying behaviors through inwrought selection to cozen their predators (Hanlon, 2007). Cephalopods belong to the divers(prenominal) Phylum, phylum phylum Mollusca. In character reference to taxonomy, Phylum Mollusca is make up of sextet different classes of thornless animals; Monoplacophora, Polyplacophora, Scaphapoda, Bivalvia, Gastropoda, and Cephalopoda. It is strange to hypothecate back that a cephalopod molluskan is indeed sort out with its th ump outed relatives. The taxonomy for a cephalopod belonging to Phylum Mollusca may parry some people. When the condition Mollusk is employ ane tends to think of the small gutless animal with the application program evasive outmost layer of one or twain shell(s). twelvemonth Monoplacophora, Polyplacophora, Scaphapoda, Bivalvia, Gastropoda, ar animals which all get shells as their protective mechanisms against predators. Each animal in the Phylum Mollusca possess a specific doodad for egis; bivalves physical exertion their adductor muscles to stay on their shells closed trance snails and marine sea slugs in the Class Gastropoda have an operculum wich serves as their authority to protect their heads during a predatory attack.\nThe fossil record shows that Cephalopods at once developed from their shelled ancestors Nautiloids and Ammonoids, they have evolved into animals that have the index to thrive and break with out the protection of a shell. However, callable t o the absence of a shell, cephalopods became an ideal fertilise for other marine predators (Norman, 2000). A shell is a concrete form of defense, so why has this ... '
