Marionfyfea Carnleyi
''Marionfyfea'' is a genus of land planarians from Antarctic Islands off New Zealand. However, a species has been described from specimens found in Europe, probably introduced. Description The genus ''Maryonfyfea'' includes land planarians of the tribe Anzoplanini that have a small and elongate body, with mouth just behind the mid body and gonopore closer to the mouth than to the posterior end. The mesenchymal musculature includes strong bundles of dorsal longitudinal muscles, weak bundles of longitudinal muscles forming a ring zone around the intestine, and small ventral bundles of mixed longitudinal and transversal muscles forming a subneural plate. The copulatory apparatus has an inverted penis and adenodactyls. Etymology The name ''Marionfyfea'' honours Marion Fyfe Marion Liddell Fyfe (1 September 1897 – 26 August 1986) was a New Zealand academic, specialising in taxonomy of planarians and other flatworms, the first woman zoology lecturer at the University of Otago, a ...

Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Land Planarian
Geoplanidae is a family of flatworms known commonly as land planarians or land flatworms. These flatworms are mainly predators of other invertebrates, which they hunt, attack and capture using physical force and the adhesive and digestive properties of their mucus. They lack water-retaining mechanisms and are therefore very sensitive to humidity variations of their environment. Because of their strict ecological requirements, some species have been proposed as indicators of the conservation state of their habitats. They are generally animals with low vagility (dispersal ability) and with very specific habitat requirements, so they can be also used to accurately determine the distribution of biogeographic realms. Today the fauna of these animals is being studied to select conservation priorities in the Atlantic rainforest in Brazil. At the other extreme, one species in this family, '' Platydemus manokwari'' has become an invasive species in both disturbed and wild habitats in the ...

Reproductive System Of Planarians
The reproductive system of planarians is broadly similar among different families, although the associated structures can vary in complexity. All planarians are hermaphrodites, so their reproductive system has a male and a female part. Both parts communicate with the surface of the body via a single opening called gonopore, which is located on the ventral side of the posterior half of the body. Male part of the reproductive system The male part of the reproductive system in planarians has a set of several testicles, distributed throughout the body in two or more rows. They are usually concentrated in the anterior two thirds of the body, although they can reach close to the posterior end. The testicles are connected to a pair of sperm ducts which run posteriorly towards the gonopore. In some groups, the sperm ducts met in their Distal#Proximal and distal 2, distal part, forming the ejaculatory duct, which then opens in a cavity called “male atrium”. In others, like land ...

Marion Fyfe
Marion Liddell Fyfe (1 September 1897 – 26 August 1986) was a New Zealand academic, specialising in taxonomy of planarians and other flatworms, the first woman zoology lecturer at the University of Otago, and the first woman to be elected to the Council of the Royal Society Te Apārangi. Academic career Fyfe was born in Kakanui in Otago on 1 September 1897 to parents Harriet and William Fyfe. Fyfe graduated with an MSc in zoology in 1935 from the University of Otago. She became the first female zoology lecturer at Otago in 1921, and was acting head of the department on occasion. Her research focussed on flatworms and particularly their reproductive processes. In 1949, Fyfe became the first woman to be elected to the Council of the Royal Society Te Apārangi. She helped first with editing of proofs for the ''Transactions of the Royal Society of New Zealand'' journal, and later became editor. She is credited with improving the quality of the journal. Fyfe retired from the U ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marionfyfea Carnleyi
''Marionfyfea carnleyi'' is a species of land planarian from Sub-Antarctic Islands of New Zealand. Description ''Marionfyfea carnleyi'' measures about 1 to 2 cm in length. The dorsum is cream and has two broad dark brown lateral stripes, while the venter is uniformly cream. The eyes are arranged in a single row around the body margin, being more concentrated at the anterior end. The pharynx The pharynx (: pharynges) is the part of the throat behind the human mouth, mouth and nasal cavity, and above the esophagus and trachea (the tubes going down to the stomach and the lungs respectively). It is found in vertebrates and invertebrates ... is long and tubular.

Worms Of New Zealand
The World Register of Marine Species (WoRMS) is a taxonomic database that aims to provide an authoritative and comprehensive catalogue and list of names of marine organisms. Content The content of the registry is edited and maintained by scientific specialists on each group of organism. These taxonomists control the quality of the information, which is gathered from the primary scientific literature as well as from some external regional and taxon-specific databases. WoRMS maintains valid names of all marine organisms, but also provides information on synonyms and invalid names. It is an ongoing task to maintain the registry, since new species are constantly being discovered and described by scientists; in addition, the nomenclature and taxonomy of existing species is often corrected or changed as new research is constantly being published. Subsets of WoRMS content are made available, and can have separate badging and their own home/launch pages, as "subregisters", such as the '' ...
