The embryonic development of the nematode Caenorhabditis elegans was examined under different gravitational conditions. The embryos after fertilization normally hatched under hypergravity (200 G) or 3D-clinorotation, whereas the number of eggs laid from an adult hermaphrodite decreased and their hatching rate was reduced under the hypergravity condition. The first cleavage plane in the 1-cell embryo was slid to some extent by re-orientation of liquid culture vessel, but the pattern and timing of cleavages were not affected.
