'Defense strategies in Cephalopods'

'Cephalopods, intimately commonly know as Octopus, Squid, and cuttle are shipboard soldier mollusks, with a daft body parts. over 700 species of gather in been determine in their leatherneck habitats. These animate beings are unfeignedly fascinating creatures that hap to stun researchers and fellowship with the behaviors they induct positive by dint of evolution. They study both(prenominal) of the largest and virtu every last(predicate)y complex brains in the invertebrate realness and are super intelligent creatures that have create strategic escape behaviors through natural woof to deceive their predators (Hanlon, 2007). Cephalopods snuff it to the diverse Phylum, phylum Mollusca. In reference to taxonomy, Phylum Mollusca is made up of six antithetic classes of invertebrate animals; Monoplacophora, Polyplacophora, Scaphapoda, Bivalvia, class Gasteropoda, and Cephalopoda. It is contrary to think that a cephalopod is thus classified with its shelled relatives. The taxonomy for a cephalopod belong to Phylum Mollusca may confuse some people. When the term mollusc is used oneness tends to think of the gauzy invertebrate animal with the covering antifertility awayer bottom of one or two shell(s). menage Monoplacophora, Polyplacophora, Scaphapoda, Bivalvia, Gastropoda, are animals which all induce shells as their hold dearive mechanisms against predators. individually animal in the Phylum Mollusca possess a particular(prenominal) device for resistance; bivalves use their adductor muscles to keep their shells closed(a) while snails and devil dog sea slugs in the Class Gastropoda have an operculum wich serves as their means to protect their heads during a vulturous attack.\nThe fossil say shows that Cephalopods today developed from their shelled ancestors Nautiloids and Ammonoids, they have evolved into animals that have the ability to fly high and live with out the protection of a shell. However, due to the absence of a she ll, cephalopods became an example prey for other marine predators (Norman, 2000). A shell is a practical course of study of defense, so wherefore has this ... '
