Description ''Amaga bogotensis'' has a large and broad, flat body. The dorsal side is grey-black, with two dark yellow stripes, one encircling the body and one mid-dorsal stripe, both around the same width. The copulatory apparatus lacks a permanent penis, but the male atrium is lined by multiple musculo-glandular papillae. The ovovitelline ducts enter the female atrium at the same time, without joining to form a common duct.

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'' () "fame, glory, honour, praise, renown, godlike" and ''berht'' "bright, light, shining"). It is the second most frequently used given name of ancient Germanic origin.Reaney & Wilson, 1997. ''Dictionary of English Surnames''. Oxford University Press. It is also in use as a surname. Another commonly used form of the name is Rupert. After becoming widely used in Continental Europe, the name 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 En ...

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, Hokkaido, 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, Kyoto, Sonobe Middle School and joined a Natural History Club. In 1946, he started his studies at the Kyoto Normal College (currently Kyoto University of Educatio ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Ludwig Von Graff
Ludwig Graff de Pancsova (2 January 1851 – 6 February 1924), known as Ludwig von Graff, was an Austrian zoologist born in Pancsova. In 1871, he received his medical degree in Vienna, afterwards studying zoology at the University of Graz. In 1872, he was an assistant at the zoological institute in Strasbourg, where he worked closely with Eduard Oscar Schmidt (1823–1886). In 1873, he relocated to Munich as an assistant to Karl Theodor Ernst von Siebold (1804–1885), gaining his habilitation during the following year. In 1876, he became a professor at the Academy of Forestry in Aschaffenburg, and from 1884 was a professor of zoology at the University of Graz. Here, he expanded the institute of zoology and its library. In 1896-97, he was rector of the university. Graff was a leading expert on Turbellaria (flatworms), especially remembered for research of its morphology and biological systematics. He gathered material for his studies on numerous expeditions, which included jour ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

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 ...
