In several species of dendrobranchiate shrimps and the euphausiacean Meganyctiphanes norvegica, early cleavage stereotypy is associated with early cell fate determination, because each interlocking band limits movement and establishes, early in development, the future position and fate of the blastomeres (Hertzler and Clark, 1992; Alwes and Scholtz, 2004; Hertzler, 2005; Biffis et al., 2009: Pawlak et al., 2010; Scholtz and Wolff, 2013; Klann and Scholtz, 2014).
Cleavage and gastrulation of the euphausiacean Meganyctiphanes norvegica (Crustacea.
The abundant later developmental stages of copepods and euphausiaceans in this area will later move to the Weddell Sea.
On the eastern coast, a divergence occurring at the latitude of Halley Bay separates the communities of the north and south of the platform, which are both dominated by the larval stages of more coastal species of copepods and euphausiaceans. The macrozooplankton includes dense swarms of chaetognaths and of Euphausia crystallorophias over the platform and of E.
