The flatworms, known as Platyhelminthes are a phylum of fascinating, simple bilaterian, unsegmented, soft-bodied invertebrate animals. Unlike other bilaterians, they have no body cavity, and no specialized circulatory and respiratory organs, which restricts them to having flattened shapes that allow oxygen and nutrients to pass through their bodies by diffusion. The digestive cavity has only one opening for both the ingestion and expulsions of undigested wastes) -this means that food cannot be processed continuously. Platyhelminthes are divided into Turbellaria, which are mostly nonparasitic animals such as planarians, and three entirely parasitic groups: Cestoda, Trematoda and Monogenea. Free-living flatworms are mostly predators, and live in water or in shaded, humid terrestrial environments such as leaf litter. We are fortunate to have as a member of BowerBird, Dr Leigh Winsor from the Jame Cook University at Townsville who is a free-living flatworm expert. Leigh is most keen for members to find and upload images of flatworms. He would also like from time to time for members to collected into alcohol flatworms they find which will be used in his DNA analysis of this difficult group of animals.

    Excellent photos of Artioposthia howitti, especially of the head showing the eyes.

    Agree with Reiner that this is Artioposthia lucasi. A nice pic of a nice specimen!

    This specimen is probably a juvenile of Caenoplana dendyi. Young specimens are generally much paler than the adult, though they have the basic colouration and pattern of the adult. The ventral surface exhibits brown mottling that will occupy the outer thirds of the ventral surface, leaving the cobalt blue along the mid-line.

    Nice photos of Caenoplana dendyi, first described from specimens obtained in November 1890 on an excursion of the Field Naturalists Club of Victoria to the country between Marysville and the source of the Yarra River along the road to Wood's point. At first gland, this species looks like Caenoplana coerulea with the dark blue-green dorsum, with median creamish stripe, and cobalt blue ventral surface. However C. dendyi differs from this species in having a fine dark median stripe in the center of the cream stripe dorsally, and only the median region of the ventral surface is cobalt blue, bordered on either side by the dark blue green ground colour. Under a lens, some specimens can exhibit a beautiful light mottling dorsally on the dark ground colour. In addition to Reiner's record, the species occurs in the eastern highlands, in the Wingan National Park, and near Glenantipy-Butcher's Ridge in east Gippsland.
