The predominant food organisms of meso- and bathypelagic Chaetognatha, Sagitta zetesios Fowler, were copepods. The percentages of Copepoda, Chaetognata, Euphausiacea, Ostracoda and unidentified in the gut, was 71.6%, 16.2%, 1.4%, 1.4% and 9.4%, respectively. The 24 species of copepods, 5 of chaetognaths and 1 of ostracods were identified and these 20 species were meso- and bathypelagic and another 10 species were epipelagic. Higher day time feeding rates were found, because Sagitta zetesios feed on epipelagic food organisms when they migrate from the upper layer during the day
