Typhloplanidae
Typhloplanidae is a family of flatworms in the order Rhabdocoela. It is one of the most species-rich families of Rhabdocoela, comprising around 300 species. They inhabit freshwater, estuarine, marine and terrestrial habitats. They can be benthic or pelagic. Typhloplanidae are predatory. They can reach high densities in their habitats. Most representatives are 1 to 5 mm in length, but a few species, like ''Mesostoma ehrenbergii ''Mesostoma ehrenbergii'' is a species of rhabdocoel flatworms in the family Typhloplanidae.

Mesostoma Ehrenbergii
''Mesostoma ehrenbergii'' is a species of rhabdocoel flatworms in the family Typhloplanidae. Description The species is comparatively large for microturbellarians, reaching 1,5 cm in body length. Its body is highly transparent. It is dorsoventrally flattened with the anterior end gradually tapering and broadly pointed, and the posterior end sharply pointed. Taxonomy It was described by Gustav Woldemar Focke as ''Planaria ehrenbergii'' in 1836. The specific name references Christian Gottfried Ehrenberg. Distribution and habitat The species has been recorded in Argentina, Brazil, Europe, Iran, Kenya, Kyrgyzstan, New Zealand, Peru, Siberia, Trinidad, and the USA. It typically occurs in ponds and lakes. Ecology and behavior The animal primarily feeds on cladocerans, but also on fairy shrimps, naidid oligochaetes, large rotifers and mosquito larvae Mosquitoes (or mosquitos) are members of a group of almost 3,600 species of small flies within the family Culicidae (f ...

Rhabdocoela
Rhabdocoela is an order of flatworms in the class Rhabditophora with about 1700 species described worldwide. The order was first described in 1831 by Christian Gottfried Ehrenberg. Most of rhabdocoels are free-living organisms, but some live symbiotically with other animals. Description Although Rhabdocoela is a highly supported group in molecular studies, there is no clear morphological synapomorphy that unites them. All rhabdocoels have a bulbous pharynx, but this is shared with other flatworm groups, such as Neodermata, Lecithoepitheliata and some species of Prolecithophora. Some possibly identified synapomorphies are found in the ultrastructure of the protonephridial system, but similar constructions exist in other groups. Another possible apomorphy is found in the ultrastructure of the sperm, which has a dense heel on the basal bodies during spermiogenesis, but some groups have lost this feature. Classification Rhabdocoels were traditionally classified in two groups, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Flatworm
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 organ (anatomy), 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 prove ...

Christian Gottfried Ehrenberg
Christian Gottfried Ehrenberg (19 April 1795 – 27 June 1876) was a German naturalist, zoologist, comparative anatomist, geologist, and microscopist. Ehrenberg was an evangelist and was considered to be of the most famous and productive scientists of his time. Early collections The son of a judge, Christian Gottfried Ehrenberg was born in Delitzsch, near Leipzig. He first studied theology at the University of Leipzig, then medicine and natural sciences in Berlin and became a friend of the famous explorer Alexander von Humboldt. In 1818, he completed his doctoral dissertation on fungi, ''Sylvae mycologicae Berolinenses.'' In 1820–1825, on a scientific expedition to the Middle East with his friend Wilhelm Hemprich, he collected thousands of specimens of plants and animals. He investigated parts of Egypt, the Libyan Desert, the Nile valley and the northern coasts of the Red Sea, where he made a special study of the corals. Subsequently, parts of Syria, Arabia and Abyss ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
