Phylogenetic relationships of the Temnocephaloidea (Platyhelminthes)m neighboring parenchymal cells in a fashion similar to paren-chymal structure in the Monogenea and Digenea. The spermatozoa have a pair of free 9+1 flagella and contain aligned dense bodies. The Temnocephaloidea is evidently derived from an early rhabdocoel-turbellarian-like ancestor.

Experimental evidence for the origins of determinative development in the polyclad turbellariansf larval eyes was a particularly useful character in revealing mosaicism. This study establishes the polyclad embryo as determinative, but with important cell interactions also occurring during early development, and provides evidence that mosaicism became associated with spiral cleavage in the quartet form during the evolution of the Turbellaria.

Eggshell formation in polyclads (Turbellaria)ts of the SFGs and the parts of the eggshell indicate that discrete parts of the shell are derived from specific SFG components. Hardening of the eggshell and egg-plate matrix takes place through primary tanning of a sclerotin-like protein.

https://doi.org/10.1007/978-1-349-04184-8as where a more integrated approach would be beneficial. This is done with particular reference to the endosymbiont genus . which belongs to the Turbellaria but which functionally has more similarities to the parasitic platyhelminths especially with regard to the host-finding requirement of the larval stages.
