The phylogenetic significance of sperm morphology in the Platyhelminthesevolution of ‘higher’ metazoans from acoels related to the recent Acoela seems highly improbable..The ultrastructure of the spermatozoa of the parasitic groups of flatworms (Monogenea, Digenea, Cesto-da) is very similar to that found in the Kalyptorhynchia, a further indication that the parasitic gr

Embryology of the Turbellaria and its phylogenetic significance is established by the occurrence of quartet 4d spiral cleavage in one neoophoran order, and of both quartet spiral cleavage and . in different species of a second neoophoran order. The epibolic gastrulation of polyclads is described as primitive for the Turbellaria because of its similarity to that
