Crassandros is a genus of flatworm belonging to the family Ilyplanidae. It is monotypic, containing the sole species Crassandros dominicanus. [1] It is found on Dominica.
Species of Crassandros are oval in shape and lack tentacles, with both cerebral and tentacular eye clusters. The ejaculatory duct is heavily muscled. [2]
C. dominicanus is around 11 mm in length, with a broad, oval shape. The color in life is unknown, but it is known to be brown when preserved. [2]
C. dominicanus is known to be found on the island of Dominica, with the holotype being found in rock pools in the village of Marigot. [2]
The Polycladida represents a highly diverse clade of free-living marine flatworms. They are known from the littoral to the sublittoral zone, and many species are common from coral reefs. Only a few species are found in freshwater habitats.
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.
Pseudoceros is a genus of the flatworms Platyhelminthes.
Geoplanidae is a family of flatworms known commonly as land planarians or land flatworms.
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. Native to Asia, several species are invasive to the United States, Canada, and Europe. Some studies have begun the investigation of the evolutionary ecology of these invasive planarians.
Girardia is a genus of freshwater planarians belonging to the family Dugesiidae.
Maritigrella crozierae, the tiger flatworm, is a species of marine polyclad flatworm in the family Euryleptidae. It is found on the eastern coasts of North America and the Caribbean Sea where it feeds on colonial sea squirts.
Pseudoceros ferrugineus, the Fuchsia flatworm, is a marine flatworm species that belongs to the Pseudocerotidae family.
Thysanozoon nigropapillosum is a species of polyclad flatworms belonging to the family Pseudocerotidae. Some common names include gold-speckled flatworm, marine flatworm, yellow papillae flatworm, yellow-spotted flatworm, and yellow-spotted polyclad flatworm.
Acanthozoon is a genus of polyclad flatworms belonging to the family Pseudocerotidae.
Pasipha is a genus of land planarians from South America.
Coeloplana astericola, the creeping comb jelly, is a species of benthic comb jelly from the tropical western Indo-Pacific region that lives as an episymbiont on starfish such as Echinaster luzonicus.
Pseudoceros canadensis, commonly known as the Puget flatworm, is a species of free-living flatworm in the genus Pseudoceros, belonging to the family Pseudocerotidae.
Kaburakia is a genus of flatworms belonging to the family Callioplanidae.
Typhloplanidae is a family of flatworms in the order Rhabdocoela.
Euplana carolinensis is a species of flatworm belonging to the family Euplanidae. It is found within the United States in North Carolina.
Anandroplana is a genus of flatworms belonging to the family Ilyplanidae.
Anandroplana muscularis is a species of flatworm belonging to the family Ilyplanidae. It is found within Puerto Rico.
Anandroplana portoricensis is a species of flatworm belonging to the family Ilyplanidae. It is found within Puerto Rico.
