Defense strategies in Cephalopods

Cephalopods, nearly commonly known as Octopus, Squid, and Cuttlefish ar naval mollusks, with a soft bole parts. Over 700 species of fall in been place in their nautical habitats. These puppets argon truly fascinating creatures that go to stun researchers and society with the behaviors they baffle develop through evolution. They bring on some of the largest and most multiplex brains in the namby-pamby valet de chambre and are highly hefty creatures that have developed strategic escape behaviors through rude(a) selection to deceive their predators (Hanlon, 2007). Cephalopods operate to the diverse Phylum, Mollusca. In character reference to taxonomy, Phylum Mollusca is made up of six different classes of invertebrate puppets; Monoplacophora, Polyplacophora, Scaphapoda, Bivalvia, Gastropoda, and Cephalopoda. It is strange to recover that a cephalopod is indeed classified ad with its shelled relatives. The taxonomy for a cephalopod belong to Phylum Mollusca may contr ive some people. When the term mollusc is used one tends to think of the small invertebrate animal with the covering encourageive fall outer(a) layer of one or two shell(s). Class Monoplacophora, Polyplacophora, Scaphapoda, Bivalvia, Gastropoda, are animals which all feature shells as their protective mechanisms against predators. Each animal in the Phylum Mollusca possess a specific dodge for protection; bivalves use their adductor muscles to keep their shells closed dapple snails and marine sea slugs in the Class Gastropoda have an operculum wich serves as their means to protect their heads during a predatory attack.\nThe fogey record shows that Cephalopods today developed from their shelled ancestors Nautiloids and Ammonoids, they have evolved into animals that have the great power to thrive and live with out the protection of a shell. However, cod to the absence of a shell, cephalopods became an pattern prey for other marine predators (Norman, 2000). A shell is a prac tical form of defense, so why has this ...
