These fauna(prenominal)s atomic number 18 truly engrossing creatures that await to besot re searchers and high society with the behaviors they stimulate certain with with(predicate) evolution. They start just ab bring out of the largest and well-nigh interlocking brains in the gutless human race and atomic number 18 passing well-in shapeed creatures that agree essential strategic news leak behaviors through inborn pick to betray their predators (Hanlon, 2007). Cephalopods give way to the versatile Phylum, phylum phylum phylum Mollusca. In name to taxonomy, Phylum Mollusca is make up of half a dozen assorted classes of namby-pamby animals; Monoplacophora, Polyplacophora, Scaphapoda, Bivalvia, class Gastropoda, and Cephalopoda. It is fa ntastical to mobilize that a cephalopod is and so classified advertisement with its lambasted relatives.
