Growth of Nyctiphanes (Euphausiacea) on different diets

Journal of Experimental Marine Biology and Ecology, 2003
Abstract To determine the effects of diet on the growth rate of Nyctiphanes australis (Euphausiacea), metanauplii were reared to mature adults in the laboratory. Sibships (siblings from the same mother) were raised on different food items collected from the field and cultured in the laboratory. A sibship was divided at the calyptopis stage and 50% of

Karyological Study of the Mediterranean Krill Meganyctiphanes norvegica (Euphausiacea)

Journal of Crustacean Biology, 1995
The chromosomes of Meganyctiphanes norvegica from the Mediterranean Ligurian Sea were investigated using standard Giemsa, silver staining, and C-banding. The karyotype of both sexes consists of 19 metacentric chromosome pairs of gradually decreasing size.

Crustacea: Euphausiacea

2017
This chapter describes the taxonomy of Euphausiacea, exclusively marine holoplanktonic crustaceans commonly known as krill. Although not highly diverse, with only two families and ~ 86 species worldwide, they are often a major component of the biomass of the plankton and micronekton of the world's oceans.

Feeding appendages of the Euphausiacea (Crustacea)

Journal of Zoology, 1967
The Euphausiacea comprises about 85 species and the structure of the feeding appendages of 68 of these species is discussed here. A considerable uniformity is apparent in the appendages throughout the order but generic, and even in some cases, specific differences are evident.

Studies on photophores in the Euphausiacea

Sarsia, 1968
Abstract The present investigation concerns the adult morphology and histology of the photophores of some euphausiids and some notes on the development of the abdominal photophores of Meganyctiphanes norvegica. Some of the more important results are abstracted. The posterior cell mass inside the reflector layer is more complicated than earlier believed.

THE RELATION BETWEEN THE SCATTERING LAYER AND THE EUPHAUSIACEA

The Biological Bulletin, 1950
The source of the scattering effect is not, at present, susceptible of direct proof, but if an organism could be found whose characteristics agreed with those of the layer on a sufficient number of points, then there would be a high probability that this is the actual source of the effect. From the diurnal migration of the layer there seems no room for

Development of the Stomach in Euphausia Superba Dana (Euphausiacea)

Journal of Crustacean Biology, 1993
ABSTRACT Development of the stomach, with emphasis on the filter system, was investigated in the metanauplius, calyptopis, and furcilia stages of the Antarctic krill Euphausia superba. The metanauplius lacks an elaborated stomach as well as a connection between the esophagus and the midgut. In calyptopis I, the stomach becomes functional.
