To better understand the ecological role of cephalopods, improved representation of these species in ecosystem models is a critical requirement and could be achieved relatively easily to more accurately articulate the mechanisms regulating the ecological role of cephalopods.Ībitía-Cardenas LA, Galván-Magaña F, Gutierrez-Sanchez FJ et al (1999) Diet of blue marlin Makaira mazara off the coast of Cabo San Lucas, Baja California Sur, Mexico. The importance of neritic species varies locally, but generally cephalopods have a substantial impact via their consumer role. Oceanic squid species have a major role linking trophic levels and food webs from different habitats. Our analysis indicated that most ecosystem models inadequately include cephalopods in terms of model structure and parametrization although some models still have the capacity to draw valuable conclusions regarding the impact and role of cephalopods within the system. We examined ecosystem models from 13 regions to analyse the representation of cephalopods and compared their results to local trophic studies. This review evaluates our representation of cephalopods in ecosystem models and the insights given by these models on the role of cephalopods in our oceans. Cephalopod ecology, however, is still poorly understood as observational studies often give highly uncertain and variable results due to the peculiarities of cephalopod behaviour and biology, and their responsiveness to external drivers. Cephalopods, especially squids, are believed to have a structuring role in marine ecosystems as a link between different trophic levels, primarily due to their voracious prey consumption and high production rate.
