The ultrastructure of the epithelium in Notentera ivanovi (Turbellaria, Fecampiida) has been studied. Notentera ivanovi lacks the digestive system but has a pad of the epidermal cells on the dorsal side of the body, which seems to be similar to the digestive epidermis on LM.

Philosophical Transactions of the Royal Society of London, 1879
Abstract Two forms of considerable interest belonging to this group were found to be tolerably abundant. They belong to the genera Tetrastemma and Geoplana, I can scarcely entertain a doubt that these animals will finally prove to have a much wider geographical range, or, in other words, that it would be premature to regard them as ...

Chemoreception in Turbellaria.
Experimental biology, 1989This paper reviews the ultrastructural features and the behavioural aspects of presumptive chemoreceptors as reported in the literature, and adds some new observations. The involvement of both uniciliary and multiciliary sensory receptors has been cited.

Entre los Platyhelminthes, los turbelarios son tradicionalmente reconocidos como la clase que agrupa a los representantes de vida libre del phylum. Sin embargo, no tienen sinapomorfías que los definan, siendo la presencia de una epidermis ciliada en el adulto la característica principal que los relaciona, carácter ausente en las formas parásitas del ...

Eggshell formation in polyclads (Turbellaria)
Hydrobiologia, 1986Eggshell formation in polyclads was studied by means of transmission electron microscopy and histochemistry. Shell-forming granules (SFG) in the egg, as well as secretions of shell glands (SGS), play roles in eggshell formation. As the oocytes pass through the portion of the female tract where the shell glands open, they are surronded by a two-layered ...

The uterine structure of a viviparous rhabdocoelic turbellarian (Rhabdocoela, Typhloplanoida, Typhloplanidae, Mesostominae) has been studied. These turbellarians produce summer eggs poor in yolk that develop in the parent’s body. It is shown that embryos receive nourishment from the parent by connecting to its uterine epithelium.

Parasitism and Commensalism in the Turbellaria
1971Publisher Summary Turbellaria are primarily free-living predators but each of their five orders contains families with representatives living in association with other animals. The commonest partners with which these associations are established include (1) echinoderms, (2) crustaceans, and (3) mollusks.

Revision of Koinocystididae (Turbellaria)
Zoologica Scripta, 1980The revision deals with the anatomy and systematics of the known 38 species of Koinocystididae. The taxonomy within the family is revised, a key for the identification of live specimens is given and an attempt is made to reconstruct the phylogeny of genera and species on the basis of anatomical transformation series. New genera are Axiutelga. Brunetia,

The musculocutaneus complex of ten planarian species from three families and two marine triclads were studied with the use of light microscopy and transmission electronic microscopy. Some differences in structure of basal plate, subepidermal and dorso-ventral musculature were found.
