    The Class Cephalopoda comprising of squids, cuttlefishes and octopus includes the largest known living invertebrates within the animal Kingdom. Cephalopods have well developed head and a body consisting of a muscular mantle and mantle cavity. Head bears circumoral appendages (arms, tentacles), a feature that reflects the origin of the name ‘Cephalopoda’, which is derived from the union of the two Greek words: ‘kefale’, head, and ‘pous’, feet. These soft-bodied bilaterally symmetrical groups are commercially important fishery resources occurring in all marine habitats in depth ranging from intertidal to over 5,000 m. Salinity is considered as the limiting factor restricting their distribution between 27 and 37 psu, with few exceptions.
