Yungia Aurantiaca
''Yungia aurantiaca'' is a species of flatworm in the family Pseudocerotidae. It is found in the temperate northeastern Atlantic Ocean and the Mediterranean Sea. Description ''Yungia aurantiaca'' is a fairly large flatworm, growing to a length of about . It is very thin and leaf-like, broadly oval in outline, with a thickened central ridge and a lobed, wavy margin. The dorsal surface is orange with fine white spots and a white margin, and the ventral surface is whitish. Some folds at the edge of the head form folds that function as tentacles. In between these is a horseshoe-shaped ring of eyespots, and the head also bears chemoreceptors. A single central opening on the underside serves both as the mouth and the anus, and opens into the pharynx; this aperture can be used as a sucker to secure the flatworm to the substrate. Ecology ''Yungia aurantiaca'' is a predator, feeding on tunicates, bryozoans and other small sedentary invertebrates. The flatworm covers its prey with its b ...

Biography In March 1876 he earned his PhD from the University of Jena, and two months later became habilitated as a privat-docent of zoology at the University of Bern. From 1878 to 1885 he was stationed at the Zoological Station in Naples, where he conducted research on wildlife native to the Gulf of Naples. In 1889 he became a professor of zoology and comparative anatomy at the University of Zurich and the '' Eidgenössische Polytechnikum'' as well as director of two institutions' zoological collections. From 1898 to 1900 he served as rector at the University of Zurich.Arnold Lang (1855 up to 1914) at ETH Bibliotek In the autumn o ...

Flatworms
The flatworms, flat worms, Platyhelminthes, or platyhelminths (from the Greek πλατύ, ''platy'', meaning "flat" and ἕλμινς (root: ἑλμινθ-), ''helminth-'', meaning "worm") are a phylum of relatively simple bilaterian, unsegmented, soft-bodied invertebrates. Unlike other bilaterians, they are acoelomates (having no body cavity), and have 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 ingestion (intake of nutrients) and egestion (removal of undigested wastes); as a result, the food cannot be processed continuously. In traditional medicinal texts, Platyhelminthes are divided into Turbellaria, which are mostly non-parasitic animals such as planarians, and three entirely parasitic groups: Cestoda, Trematoda and Monogenea; however, since the turbellarians have since been proven not to be mono ...
