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.

Euphausiacea

2022
AbstractEuphausiacea were once united with “mysidaceans” in a more inclusive taxon, Schizopoda, “split legs,” so named for their biramous thoracopods. Both of these schizopods stood as almost perfect caridoids, expressing the “caridoid facies” that Calman utilized to create the ancestral malacostracan.
