The polyclads are of particular interest because they provide a link between the regulative development of acoels and the determinative development of annelids and molluscs. Single blastomeres were deleted at the two- and four-cell stages by puncture through the eggshell membrane with tungst

This envelope prevents the dispersion of SFGs discharged after oviposition, and
