Cephalopods in the North-Eastern Atlantic: Species, Biogeography, Ecology, explotation and conservation
Cephalopods play a significant role in coastal and oceanic ecosystems. both as consumers of invertebrates and small fish and as the prey of some fish, seabirds and marine mammals and other large predators. Approximately 30 species of cephalopod have been recorded in the north-eastern Atlantic and ad...

Cephalopods play a significant role in coastal and oceanic ecosystems. both as consumers of invertebrates and small fish and as the prey of some fish, seabirds and marine mammals and other large predators. Approximately 30 species of cephalopod have been recorded in the north-eastern Atlantic and adjacent waters, including 18 teuthid (squid), seven sepiolid (bobtail), three sepiid (Cuttlefish) and 10 octopod (Octopus) species.
