Abstract According to the `Articulata' hypothesis the
cleavage of arthropods must be derived from spiral
cleavage. However, arthropods show a great variety of
cleavage modes with a widespread occurrence of super-
ficial cleavage. In the Malacostraca, holoblastic cleavage
occurs in some taxa such as Amphipoda, Euphausiacea
and Dendrobranchiata. In particular, the cleavage of
euphausiaceans has been proposed to be a modified spiral
cleavage. The cell lineage of early stages up to blasto-
derm formation of the euphausiacean Meganyctiphanes
norvegica is reconstructed using recent methods of
fluorescent staining. Only the oblique angle of the mitotic
