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.

Pseudoceros Canadensis
''Pseudoceros canadensis'', commonly known as the Puget flatworm, is a species of free-living flatworm in the genus ''Pseudoceros'', belonging to the family Pseudocerotidae. Physical characteristics These flatworms are acoelomate bilaterians. They lack respiratory and circulatory systems and therefore diffuse oxygen and CO2 through the body surface, which is made possible due to them being highly flattened, which increases their surface area to volume ratio. However, this limits their maximum in size. They possess digestive systems, which allows them to process complex dietary items. They possess a protrusible pharynx to collect food. Platyhelminthes have a high degree of cephalization with an obvious head-end. ''Pseudoceros'' have a distinctive anterior folding of the body to make 2 tentacles known as "false horns". Vision The right cerebral eye of the larval stage has 1 cup-shaped pigment cell & 3 sensory cells that have microvilli. The left eye of the larval stage is comp ...

Pseudoceros Dimidiatus
''Pseudoceros dimidiatus'', the divided flatworm or tiger flatworm, is a species of flatworm in the genus ''Pseudoceros'', belonging to the family Pseudocerotidae. Description ''Pseudoceros dimidiatus'' grows to be up to . The body is elongated and oval, with a velvety dorsal surface, a grey-black ventral side and quite short pseudo tentacles formed by folds of the anterior margin. All divided flatworms have a black body with an orange margin. Common characters are also two wide longitudinal yellow-greenish stripes usually separated by a narrow black median line. However, this species of ''Pseudoceros'' is highly variable in colour and in pattern, in terms of the arrangement and width of the various transverse stripes and of the width of the longitudinal stripes. It can take at least three different types of liveries, all with the same colours, which threaten its being inedible. It has bilateral symmetry. The bright and contrasting colors serve as a warning for predators to n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pseudocerotidae
Pseudocerotidae is a family of flatworm Platyhelminthes (from the Greek language, Greek πλατύ, ''platy'', meaning "flat" and ἕλμινς (root: ἑλμινθ-), ''helminth-'', meaning "worm") is a Phylum (biology), phylum of relatively simple bilaterian, Segmentation (biology), ...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
Platyhelminthes (from the Greek language, Greek πλατύ, ''platy'', meaning "flat" and ἕλμινς (root: ἑλμινθ-), ''helminth-'', meaning "worm") is a Phylum (biology), phylum of relatively simple bilaterian, Segmentation (biology), unsegmented, soft-bodied invertebrates commonly called flatworms or flat worms. Being acoelomates (having no coelom, body cavity), and having no specialised circulatory system, circulatory and respiratory system, respiratory organ (anatomy), organs, they are restricted 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 can not 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, Trematod ...
