Abstract
Cephalopods are ecologically and commercially important invertebrates with a wealth of extant marine taxa spanning from neritic continental shelf to the abyssal plains. The class Cephalopoda includes two, distantly related, extant subclasses, the primitive Nautiloidea, represented by the externally shelled nautiluses; and Coleoidea, which includes the ten-armed squids & cuttlefishes and the eight-armed octopuses. The commercial importance of this exclusive marine mollusc has risen in the last six decades remarkably across a highly diverse set of cephalopod taxa. The positive trend in cephalopod abundance has been attributed to a range of coastal and oceanic environmental changes, together with the potential release of cephalopods from predation and competition pressures (Doubleday et al., 2016). The fishery mainly targets the coastal species of squid, cuttlefish and octopus besides the oceanic squids when encountered within the operational range of commercial fleets while undertaking migration (Rodhouse et al., 2014).
