Ontogenetic vertical migration of the mesopelagic carnivorous copepod Paraeuchaeta spp. is related to their increase in body mass
Two dominant mesopelagic carnivorous Paraeuchaeta copepods, Paraeuchaeta glacialis in the western Arctic Ocean and Paraeuchaeta elongata in the western subarctic Pacific, exhibited specialized ontogenetic vertical migration patterns with deeper occurrences of early copepodids (C1) and adults (C6F/M)...
