Abstract
The cells of the body cavity of Phallusia mammillata larvae were exami ned by transmission electron microscopy before hatching, after it and at the beginning of tail retraction. The results revealed the presence - both before and after hatching - of cells with small electron-lucen t vacuoles, which might be the precursors of the monovacuolated cells observed at the beginning of tail retraction. These cells share morpho logical characteristics with the vanadium-accumulating signet ring cel ls of the blood of adults.
