| Abstract: | Larvae of Meganyctiphanes norvegica (M. Sars), caught with a plankton net, were reared in the laboratory from the calyptopis phase onwards, under different temperature and trophic conditions. Eyestalk ablation was performed on the first furciliae. Data are presented on growth, moulting rate and ontogenesis of the larvae as a function of the varying experimental conditions, and on larval morphology, pigmentation and diet. Recent modifications of larval nomenclature in euphausiids are discussed.
