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.

    Lovely photos of a spectacular planarian with which I am familiar. Great to have another record of this undescribed species. At this stage I am referring to it as a Caenoplana species, though in fact I suspect that it is a new genus. I have a specimen preserved for both DNA and morphological analysis.

    Hi Tom, It is hard from the photo to decide whether the planarian has a white mid-dorsal longitudinal stripe, or whether the "stripe" is simply reflected light. If the specimen has a white dorsal stripe, then it is one of the "Caenoplana coerulea" complex; if it has no white dorsal stripe, then it is Caenoplana spenceri. Both are found in this region of Victoria.

    Hi Leigh, thank you for the correction, confirmation, comments and information about my three flatworm postings. I have altered the title of my Flechmania post to reflect your ID.

    Nice photos of Fletchamia mediolineata. Fletchamia m'mahoni does not have a dark median dorsal stripe. Rather, it has paired dark lateral dorsal stripes.
