Novibipalium Murayamai
''Novibipalium'' is a genus of land planarians of the subfamily Bipaliinae (hammerhead flatworms). Description Species of ''Novibipalium'' are very similar to those of the related genus ''Bipalium''. The main difference occurs in the copulatory apparatus, which in ''Novibipalium'' lacks a well-developed penis papilla, while in ''Bipalium'' a penis papilla is present. ''Novibipalium'' has a set of folds in the copulatory apparatus that are everted during mating and create a temporary penis.

Masaharu Kawakatsu
is a Japanese zoologist known for his studies on the taxonomy and ecology of planarians. Life Masaharu Kawakatsu was born in 1929 in the Asahi village, Kameoka town, Kyoto Prefecture, Japan, son of Masakazu Kawakatsu, a squire of the village, and Tei Kawakatsu (born Okajima), the daughter of a country medical doctor, Ei'ichi Okajima.Kawakatsu, M. (2008Short reminiscences of a Turbellariologist - At the occasion of his 79th birthday ''Kawakatsus' Web Library on Planarians'', 29 Jan 2008: 1-15. After his mother died of an acute pneumonia when he was 7 years old, Kawakatsu became closer to his maternal grandfather, who had a passion for sciences, and learned from him the names of many plants and animals that grew around the house, including their scientific names. In April 1941, he attended the Sonobe Middle School and joined a Natural History Club. In 1946, he started his studies at the Kyoto Normal College (currently Kyoto University of Education), at the time an education ...

Robert E
The name Robert is an ancient Germanic given name, from Proto-Germanic "fame" and "bright" (''Hrōþiberhtaz''). Compare Old Dutch ''Robrecht'' and Old High German ''Hrodebert'' (a compound of '' Hruod'' ( non, Hróðr) "fame, glory, honour, praise, renown" and ''berht'' "bright, light, shining"). It is the second most frequently used given name of ancient Germanic origin. It is also in use as a surname. Another commonly used form of the name is Rupert. After becoming widely used in Continental Europe it entered England in its Old French form ''Robert'', where an Old English cognate form (''Hrēodbēorht'', ''Hrodberht'', ''Hrēodbēorð'', ''Hrœdbœrð'', ''Hrœdberð'', ''Hrōðberχtŕ'') had existed before the Norman Conquest. The feminine version is Roberta. The Italian, Portuguese, and Spanish form is Roberto. Robert is also a common name in many Germanic languages, including English, German, Dutch, Norwegian, Swedish, Scots, Danish, and Icelandic. It can be use ...

Eudóxia Maria Froehlich
Eudóxia Maria Froehlich (21 October 1928 – 26 September 2015) was a Brazilian zoologist. Life Born in 1928, Eudóxia Maria de Oliveira Pinto was the daughter of Alice Alves de Camargo and the ornithologist Olivério Mário de Oliveira Pinto. Since she was a child, her parents used to take her and her siblings to the wooded areas near São Paulo, which helped her to become interested in zoology, especially small animals.Carbayo, F. (2013) "Vida de Zoólogo: Eudóxia Maria Froehlich." ''Informativo da Sociedade Brasileira de Zoologia'' 106: 7–10. After finishing High School, she spent six months in Rio de Janeiro with an uncle who was a physician and returned home interested in studying medicine. Her father did not approve the idea, considering it an inappropriate career for a woman, and suggested her to study natural history and so she did. During this time she became engaged to Claudio Gilberto Froehlich, one of her colleagues. In 1951 she and Froehlich started their doct ...

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 ...

Bipaliinae
Bipaliinae is a subfamily of land planarians found mainly in Madagascar, the Indian subcontinent and Southeast Asia, although some species have been introduced worldwide. Description The subfamily Bipaliinae is characterized by having a semilunar head that gives them the common name "hammerhead worms". The head has peripheral sensory pits on the ventral side and small peripheral eyes on the dorsal side.Winsor, L.; Johns, P. M.; Barker, G. M. (2004). Terrestrial planarians (Platyhelminthes: Turbellaria: Tricladida: Continenticola) predaceous on terrestrial gastropods. ''In'': Barker, G.

Bipalium
''Bipalium'' is a genus of large predatory land planarians. They are often loosely called "hammerhead worms" or "broadhead planarians" because of the distinctive shape of their head region. Land planarians are unique in that they possess a "creeping sole", a highly ciliated region on the ventral epidermis that helps them to creep over the substrate. Several species are considered invasive to the United States, Canada, and to Europe. Some studies have begun the investigation of the evolutionary ecology of these invasive planarians. Etymology The name ''Bipalium'' comes from Latin ''bi-'', "two" + ''pala'', "shovel" or "spade", because species in this genus resemble a pickaxe. Description The genus ''Bipalium'' was initially defined by Stimpson to include land planarians with the head broadened, forming a head plate. Later, in 1899, Ludwig von Graff divided it into three genera according to the shape of the head: #''Bipalium'': with a well-developed head plate, much broader ...

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 part, forming the ejaculatory duct, which then opens in a cavity called “male atrium”. In others, like land planarians, both open in the ...

Mating
In biology, mating is the pairing of either opposite-sex or hermaphroditic organisms for the purposes of sexual reproduction. ''Fertilization'' is the fusion of two gametes. ''Copulation'' is the union of the sex organs of two sexually reproducing animals for insemination and subsequent internal fertilization. Mating may also lead to external fertilization, as seen in amphibians, fishes and plants. For most species, mating is between two individuals of opposite sexes. However, for some hermaphroditic species, copulation is not required because the parent organism is capable of self-fertilization (autogamy); for example, banana slugs. The term ''mating'' is also applied to related processes in bacteria, archaea and viruses. Mating in these cases involves the pairing of individuals, accompanied by the pairing of their homologous chromosomes and then exchange of genomic information leading to formation of recombinant progeny (see mating systems).
