Description
The Atlantic codlet is a small mesopelagic fish of the family Bregmacerotidae reaching about 8 cm. The slender, silvery body is distinguished by a long, free ray ('antenna') on the nape and by the long dorsal and anal fins, each interrupted in the middle by a finless zone. The species occurs worldwide in tropical and subtropical seas, including the warmer Atlantic, and lives in open water at moderate depth. It makes a daily vertical migration and feeds on small zooplankton such as copepods. Because of its small size it has no fishery importance, but it is numerous in the plankton.
