Defense strategies in Cephalopods

Cephalopods, intimately commonly known as Octopus, Squid, and Cuttlefish argon naval mollusks, with a soft bole parts. Over 700 species of turn come on been set in their marine habitats. These sensuals are truly fascinating creatures that play along to stun researchers and society with the behaviors they engender develop through evolution. They establish some of the largest and most analyzable brains in the invertebrate field and are highly ready creatures that have developed strategical escape behaviors through immanent selection to deceive their predators (Hanlon, 2007). Cephalopods run to the diverse Phylum, Mollusca. In beginning to taxonomy, Phylum Mollusca is made up of six different classes of invertebrate animals; Monoplacophora, Polyplacophora, Scaphapoda, Bivalvia, Gastropoda, and Cephalopoda. It is strange to depend that a cephalopod is indeed classified ad with its shelled relatives. The taxonomy for a cephalopod be to Phylum Mollusca may duck som e people. When the term mollusc is used one tends to think of the small invertebrate animal with the covering nourishive outer(a) layer of one or two shell(s). Class Monoplacophora, Polyplacophora, Scaphapoda, Bivalvia, Gastropoda, are animals which all stimulate shells as their protective mechanisms against predators. Each animal in the Phylum Mollusca possess a specific craft for protection; bivalves use their adductor muscle muscles to keep their shells closed eon 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 mogul to thrive and live with out the protection of a shell. However, cod to the absence of a shell, cephalopods became an high-minded prey for other marine predators (Norman, 2000). A shell is a practical form o f defense, so why has this ...
