Pseudocerotidae - Pseudoceros Dimidiatus
Pseudocerotidae is a family of flatworm The flatworms, flat worms, Platyhelminthes, or platyhelminths (from the Greek πλατύ, ''platy'', meaning "flat" and ἕλμινς (root: ἑλμινθ-), ''helminth-'', meaning "worm") are a phylum of relatively simple bilaterian, unsegment ...s which includes the Bedford's flatworm. Pseudocerotidae are simple organisms categorized by their oval bodies and tentacles and bright colors. They use the cilia to glide along surfaces. Most commonly referred to as marine flatworms, closely related to the orders Macrostomorpha and Lecithoepitheliata. These organisms have very complex reproductive systems, no blood systems or organs for gas exchange, a simple brain and are hermaphroditic. Habitat Due to the anthropogenic transportation of non-native marine species, their species can be found all around the world in tropical and subtropical waters near coral reefs, shallow reefs, deep waters, water surfaces and in aquaculture areas.

Flatworm
The flatworms, flat worms, Platyhelminthes, or platyhelminths (from the Greek πλατύ, ''platy'', meaning "flat" and ἕλμινς (root: ἑλμινθ-), ''helminth-'', meaning "worm") are a phylum of relatively simple bilaterian, unsegmented, soft-bodied invertebrates. Unlike other bilaterians, they are acoelomates (having no body cavity), and have no specialized circulatory and respiratory organ (anatomy), organs, which restricts them 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 cannot 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 prove ...

Libbie Hyman
Libbie Henrietta Hyman (December 6, 1888 – August 3, 1969), was a U.S. zoologist. She wrote numerous works on invertebrate zoology and the widely used '' A Laboratory Manual for Comparative Vertebrate Anatomy'' (1922, revised in 1942). Life Born in Des Moines, Iowa, she was the daughter of Joseph Hyman and Sabina ('Bena') Neumann. Hyman's father, a Polish/Russian Jew, adopted the surname when he immigrated to the United States as a youth. He successively owned clothing stores in Des Moines, in Sioux Falls, South Dakota, and in Fort Dodge, Iowa, but the family's resources were limited. Hyman attended public schools in Fort Dodge. At home she was required to do much of the housework. She enjoyed reading, especially books by Charles Dickens in her father's small den, and she took a strong interest in flowers, which she learned to classify with a copy of Asa Gray's '' Elements of Botany''. She also collected butterflies and moths and later wrote, "I believe my interest in nature i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coral Outcrop Flynn Reef
Corals are marine invertebrates within the class Anthozoa of the phylum Cnidaria. They typically form compact colonies of many identical individual polyps. Coral species include the important reef builders that inhabit tropical oceans and secrete calcium carbonate to form a hard skeleton. A coral "group" is a colony of very many genetically identical polyps. Each polyp is a sac-like animal typically only a few millimeters in diameter and a few centimeters in height. A set of tentacles surround a central mouth opening. Each polyp excretes an exoskeleton near the base. Over many generations, the colony thus creates a skeleton characteristic of the species which can measure up to several meters in size. Individual colonies grow by asexual reproduction of polyps. Corals also breed sexually by spawning: polyps of the same species release gametes simultaneously overnight, often around a full moon. Fertilized eggs form planulae, a mobile early form of the coral polyp which, when matu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Adolph Eduard Grube
Adolph Eduard Grube (18 May 1812, Königsberg – 23 June 1880 , Breslau) was a German zoologist. Adolph Eduard Grube, an able worker in many animal groups, was mainly interested in Polychaetes. In 1837 he defended his thesis at the University of Königsberg (then in Prussia). From 1843-1856 he was Professor of Zoology in the Universität Dorpat (then in Livonia) then at the Universität Breslau (now the University of Wrocław). He was one of the early scientific explorers of the Adriatic Sea. Works Partial list *1850. "Die Familien der Anneliden".

Pseudoceros
''Pseudoceros'' is a genus of the flatworms Platyhelminthes. Description Easily recognized features within the genus include a ruffled pharynx, branched intestines, and tentacles on the leading edge. The tentacles may act as chemoreceptors and may also have primitive eyes, simple light-sensitive cells, on them. The Polyclad worms are acoelomates and bilaterally symmetrical. Color is the main identifier within the family Pseudocerotidae to separate it into genera, as it can be difficult to distinguish internal reproductive anatomy between genera. Because of the similarities in body plan and structure, it is assumed that chemical cues are how these organisms can recognize their own species and differentiate between others. The intense coloring and patterning on these flatworms could be used to camouflage with their surroundings, confuse and elude predators, to communicate with other members of the species, or as aposematism to warn predators of their deadly toxins.

Pseudobiceros
''Pseudobiceros'' is a genus of flatworms. Like all flatworms, Pseudobiceros are hermaphrodites. This particular genus engages in penis fencing. When the "winner" touches its penis to the "skin" of the other, insemination occurs, and the "loser" has to bear the burden of motherhood. Species The following species are recognised in the genus ''Pseudobiceros'': *'' Pseudobiceros apricus'' Newman & Cannon, 1994 *'' Pseudobiceros bajae'' (Hyman, 1953) *''Pseudobiceros bedfordi'' (Laidlaw, 1903) *'' Pseudobiceros brogani'' Newman & Cannon, 1997 *'' Pseudobiceros caribbensis'' Bolanos, Quiroga & Litvaitis, 2007 *'' Pseudobiceros cinereus'' (Palombi, 1931) *'' Pseudobiceros damawan'' Newman & Cannon, 1994 *'' Pseudobiceros dendriticus'' (Prudhoe, 1989) *'' Pseudobiceros flavocanthus'' Newman & Cannon, 1994 *'' Pseudobiceros flavolineatus'' (Prudhoe, 1989) *'' Pseudobiceros flowersi'' Newman & Cannon, 1997 *'' Pseudobiceros fulgor'' Newman & Cannon, 1994 *'' Pseudobiceros fulvogriseus'' (H ...

Pseudobiceros Bedfordi
''Pseudobiceros bedfordi'' (common names Persian carpet flatworm and Bedford's flatworm) is a species of flatworm in the family Pseudocerotidae. This species has two penises, which it uses to engage in penis fencing, attempting to inject sperm into its opponent in order to fertilize it, while simultaneously avoiding being fertilized by their opponent. Description ''Pseudobiceros bedfordi'' is a large polyclad flatworm approximately 8–10 cm in length. It has a distinctive pattern consisting of a brown to black background, with multiple transverse, bilateral pink lines around thousands of tightly spaced, bright yellow spots,Richmond, Matthew D. (1997), ''A Field Guide to the Seashores of Eastern Africa and the Western Indian Ocean Islands'', IDA/Department for Research Cooperation, SAREC, , p. 154 pink undulating spots with stripes on the sides of the body.
