Feeding behavior of juveniles of the planktonic shrimp Lucifer faxoni Borradaile was studied in the laboratory under light and dark conditions. Newly-hatched nauplii and metanauplii of Artemio were used as prey organisms. The fecding raie of L. foxoni was dependent on prey size and prey density, but was not obviously affected by light or dark conditions. The capture of the prey tended to increase with longer exposure time to prey. The maximum ingestion rate was 17.28 and 13.40 nauplii.L. faxoni .d- , in the light and in the dark conditions, respectively.
