Pseudocerotidae
Pseudocerotidae is a family of flatworms 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. The most biodiverse areas with these species are the Caribbean and Indo-Pacific regions. Diet The feeding methods of pseudocerotidae are most intriguing, due to their soft bodies and slow movements they must prey on other organisms with little to no moveme ...

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 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.

Acanthozoon
''Acanthozoon'' is a genus of polyclad flatworms belonging to the family Pseudocerotidae. Description The genus ''Acanthozoon'' is physically characterized by a dorsal side with small raised papillae and ruffled edges. Their body is elongate oval. The species of this genus have a complex and very folded pharynx. They also have small pseudo-tentacles that prick up like ears. Because of their papillated upper surface, they are easily confused with species from the genus ''Thysanozoon'', which are also endowed with dorsal papillae. However Acanthozoon possess only a single male copulative organ contrary to Thysanozoon. Biology This genus live in warm tropical marine waters. They are benthic and carnivorous. Species list The following species are recognised in the genus ''Acanthozoon'': *'' Acanthozoon albopapillosum'' Hyman, 1959 *'' Acanthozoon albopunctatum'' Prudhoe, 1977 *'' Acanthozoon alderi'' ( Collingwood, 1876) *'' Acanthozoon allmani'' ( Collingwood, 1876) *'' Acantho ...

Maiazoon
''Maiazoon'' is a genus of marine flatworms in the family Pseudocerotidae. It is monotypic, being represented by the single species ''Maiazoon orsaki'', commonly known as the Orsak flatworm. Distribution and habitat It is found in the tropical Indo-Pacific from the Maldives to Micronesia. They inhabit the exposed edges of the reef crest and in boulders covered with coralline algae. Description ''Maiazoon orsaki'' can grow up to . It possesses a stretched "egg-shaped" body with a ruffled margin, the posterior part of the body is isentagled. The background color can generally go from translucent cream to light brown with a fine median white line. The white line starts back from the eye spots and ends just before the border of the posterior edge. The circumference of the body is ornated with an orange-brown strip and highlighted on the outside by a fine black line. The ventral face presents a similar color to the dorsal face with the white median line less." Behaviour Benthi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

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).

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 ...
