New York: McGraw-Hill New York 1974, 339-401. Description All species of Dugesiidae live in freshwater environments and have a dorsoventrally flattened body. The head usually has a somewhat triangular shape and has two eyes (except for some subterranean eyeless species). The main differences between Dugesiidae and other freshwater planarians are related to the anatomy of the eyes and the copulatory apparatus. The eye ...

Dugesia Subtentaculata
''Dugesia subtentaculata'' is a species of planarian that inhabits the freshwater of Southern France, several localities on the Iberian Peninsula (including Catalonia), Mallorca, Morocco and Algeria. In 1986 Elizabeth J. De Vries, De Vries designated a neotype for ''D. subtentaculata'' after the Holotype, original type material was lost. She also Synonym (taxonomy), synonymized the species ''D. iberica'', described from Mallorca and Iberian Peninsula, with ''D. subtentaculta''. Both the neotype and the holotype are from the surroundings of Montpellier, from a Type locality (biology), locality where asexual specimens of ''D. subtentaculata'' and sexual individuals of ''Dugesia gonocephala, D. gonocephala'' are found living together. Phylogeny ''Dugesia subtentaculata'' is related to other European ''Dugesia'' species. However, its exact phylogenetic position is not known.

Dugesia Benazzii
''Dugesia'' (pronounced, /duˈd͡ʒiʒ(i)ə/) is a genus of dugesiid triclads that contains some common representatives of the class Turbellaria. These common flatworms are found in freshwater habitats of Africa, Eurasia, and Australia. ''Dugesia'' is best known to non-specialists because of its regeneration capacities. ''Dugesia'' is the type genus of the family Dugesiidae. Description ''Dugesia'' species have an elongated body with a slightly triangle-shaped head. Usually they have grey, brown or black colors on the dorsal body surface, the ventral surface uses to be paler. These animals have a couple of eyes constituted by a multicellular pigmented cup with many retinal cells to detect the amount of light in the nearby environment. Sometimes they present supernumerary eyes. At the anterior part of the body, behind the eyes level, they have two of structures called auricles that give the triangle look to the 'head' and that allow them to detect the intensity of water curren ...

Triclad
A planarian is one of the many flatworms of the traditional class Turbellaria. It usually describes free-living flatworms of the order Tricladida (triclads), although this common name is also used for a wide number of free-living platyhelminthes. Planaria are common to many parts of the world, living in both saltwater and freshwater ponds and rivers. Some species are terrestrial and are found under logs, in or on the soil, and on plants in humid areas. The triclads are characterized by triply branched intestine and anteriorly situated ovaries, next to the brain. Today the order Tricladida is split into three suborders, according to their phylogenetic relationships: Maricola, Cavernicola and Continenticola. Formerly, the Tricladida was split according to habitats: Maricola, which is marine; Paludicola which inhabits freshwater; and Terricola, which is land-dwelling. Planaria exhibit an extraordinary ability to regenerate lost body parts. For example, a planarian split lengt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dugesia Japonica
''Dugesia japonica'' is a species of freshwater planarian that inhabits freshwater bodies of East Asia, including Japan, Korea, Taiwan, China and northeastern Siberia. However, molecular studies suggest that ''Dugesia japonica'' is polyphyletic A polyphyletic group is an assemblage of organisms or other evolving elements that is of mixed evolutionary origin. The term is often applied to groups that share similar features known as homoplasies, which are explained as a result of conver ... and different populations across its area of occurrence constitute distinct species.

However, the influence of space conditions on this phenomenon is debated. References {{Taxonbar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
