Migratory patterns, vertical distributions and diets of Abralia veranyi and Abraliopsis morisii (Cephalopoda: Enoploteuthidae) in the eastern North Atlantic
Abstract Abralia veranyi and Abraliopsis morisii were the most abundant cephalopods caught during epipelagic and mesopelagic surveys off the Canary Islands and accounted for 26% and 35% of the cephalopod catch, respectively. Diel vertical migration patterns were observed in both species. At night, A...
