Micropharynx
''Micropharynx'' is a genus of planarian placed ''incertae sedis'' in the suborder Maricola Maricola is a suborder of triclad flatworms including species that mainly inhabit salt water environments. However, some species are also known from freshwater or brackish waters.Ball, I. R. 1974.

Maricola
Maricola is a suborder of triclad flatworms including species that mainly inhabit salt water environments. However, some species are also known from freshwater or brackish waters.Ball, I. R. 1974. La Faune Terrestre de l'Ile de Saint Hélène: Turbellaria Tricladida. Ann. Mus. Roy. Afr. Centrale, in 8. Zool. Taxonomy and phylogeny History The Maricola group was first proposed by Hallez in 1892. He recognized three families: Otoplanida, Procerodida and Bdellourida. Two years later, in 1884, Hallez renamed these families as Otoplanidae, Procerodidae and Bdellouridae. In 1906 Böhmig classified the Maricola in two families and five subfamilies: Procerodidae (Euprocerodinae, Cercyrinae, Micropharynginae) and Bdellouridae (Uteriporinae, Eubdellourinae). In 1909 Wilhelmi wrote a monograph on the group in which five families were described: Procerodidae, Uteriporidae, Cercyridae, Bdellouridae, Micropharyngidae. Von Graff used the same classification in 1916. In 1989 Sluys recognized ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Axel Leonard Jägerskiöld
Axel Krister Edward Leonard Jägerskiöld (November 12, 1867 – August 4, 1945) was a Finland-born Swedish zoologist. He collected specimens across Scandinavia despite problems in vision and hearing and was a curator at the Gothenburg museum. His early work was on nematodes but later worked on birds and marine biology. Life and work Jägerskiöld was born on Mejlan estate in Finland, Nyland county where his father Gustaf Magnus Leonard (1831–71) was a captain in the Russian navy. After the death of his father, he moved to Stockholm when his mother Johanna Vilhelmina Augusta married her cousin A. H. Ramsay. Baron Gustaf Mannerheim was a distant cousin. He studied at Stockholm and because of poor health, outdoor activities were recommended. He became interested in hunting, sailing and long walks where he was inspired to study nature by his teacher Alexander Skånberg and his cousin professor Christian Loven. He moved to Uppsala with his mother who was widowed again and joined t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Planarian
Planarians (triclads) are free-living flatworms of the class Turbellaria, order Tricladida, which includes hundreds of species, found in freshwater, marine, and terrestrial habitats.pp 3., "Planarians (the popular name for the group as a whole), or triclad flatworms (the more scientific designation of the same group), are acoelomate bilaterians". Planarians are characterized by a three-branched intestine, including a single anterior and two posterior branches. Their body is populated by adult stem cells called neoblasts, which planarians use for regenerating missing body parts. Many species are able to regenerate any missing organ, which has made planarians a popular model in research of regeneration and stem cell biology. The genome sequences of several species are available, as are tools for molecular biology analysis. The order Tricladida is split into three suborders, according to their phylogenetic relationships: Maricola, Cavernicola and Continenticola. Formerly, th ...

Incertae Sedis
or is a term used for a taxonomy (biology), taxonomic group where its broader relationships are unknown or undefined. Alternatively, such groups are frequently referred to as "enigmatic taxa". In the system of open nomenclature, uncertainty at specific taxonomic levels is indicated by (of uncertain family), (of uncertain suborder), (of uncertain order) and similar terms. Examples * The fossil plant ''Paradinandra, Paradinandra suecica'' could not be assigned to any family, but was placed ''incertae sedis'' within the order Ericales when described in 2001. * The fossil ''Gluteus minimus (fossil), Gluteus minimus'', described in 1975, could not be assigned to any known animal phylum. The genus is therefore ''incertae sedis'' within the kingdom Animalia. * While it was unclear to which order the New World vultures (family Cathartidae) should be assigned, they were placed in Aves ''incertae sedis''. It was later agreed to place them in a separate order, Cathartiformes. * Boc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Platyhelminthes
Platyhelminthes (from the Greek πλατύ, ''platy'', meaning "flat" and ἕλμινς (root: ἑλμινθ-), ''helminth-'', meaning "worm") is a phylum of relatively simple bilaterian, unsegmented, soft-bodied invertebrates commonly called flatworms or flat worms. Being acoelomates (having no body cavity), and having no specialised circulatory and respiratory organs, they are restricted 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 can not 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 monophyletic, this classification i ...
