The original description of the nemertodermatid flatworm,Meara stichopi, reported the occurrence of distinct “restitution cells” in the epidermis. An ultrastructural investigation of these objects was undertaken. We found cell bodies with an ultr

Convolutriloba retrogemma Hendelberg & Akesson is an acoelous turbellarian with symbiotic algae in its parenchyma. It can reproduce asexually by budding at the posterior edge of the body. The number and position of the buds as well as their final siz
