Acanthozoon is a genus of polyclad flatworms belonging to the family Pseudocerotidae.
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. [2]
This genus live in warm tropical marine waters. They are benthic and carnivorous.
The following species are recognised in the genus Acanthozoon: [3]
The New Zealand flatworm is a large land flatworm native to New Zealand. It can vary from 5 mm in length when hatched to approximately 17 centimetres (6.7 in) in mature adults.
The Reverend Thomas Roscoe Rede Stebbing was a British zoologist, who described himself as "a serf to natural history, principally employed about Crustacea". Educated in London and Oxford, he only took to natural history in his thirties, having worked as a teacher until then. Although an ordained Anglican priest, Stebbing promoted Darwinism in a number of popular works, and was banned from preaching as a result. His scientific works mostly concerned crustaceans, especially the Amphipoda and Isopoda, the most notable being his work on the amphipods of the Challenger expedition.
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.
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.
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.
Glossodoris is a genus of sea slugs, dorid nudibranchs, shell-less marine gastropod mollusks in the family Chromodorididae.
Robert Boog Watson FRSE was a Scottish malacologist and minister of the Free Church of Scotland best known as the author of the report on the Scaphopoda and Gastropoda collected during the H.M.S. Challenger expedition to survey the world's oceans from 1873 to 1876. Watson also described various Opisthobranchia from Madeira.
Goniobranchus gleniei is a species of colourful sea slug, a dorid nudibranch, a marine gastropod mollusc in the family Chromodorididae.
Goniobranchus fidelis, also commonly known as the faithful sea slug, is a species of colourful sea slug, a dorid nudibranch, a marine gastropod mollusc in the family Chromodorididae.

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.
Geoplaninae is a subfamily of land planarians endemic to the Neotropical region. Members of this family are sometimes referred to as the Neotropical land planarians. However, one species, Obama nungara has been introduced in Europe.
Obama nungara is a species of land planarian in the family Geoplanidae. It is native to South America, but has been introduced in Europe.
John Robertson Henderson CIE FRSE FZS FLS was a Scottish zoologist who specialized in the taxonomy of marine crustaceans, particularly the decapods, and worked on specimens collected by the oceanic research vessels Investigator and Challenger. From 1892 until 1911 he was Professor of Zoology at Madras Christian College in India. From 1908 to 1920 he was Superintendent of the Government Museum in Madras. He also took an interest in numismatics and Indian history.
Gigantea maupoi is a species of land planarian belonging to the subfamily Geoplaninae. It is known from specimens collected near Medellín, Colombia.
Geoplana vaginuloides is a species of land planarian belonging to the subfamily Geoplaninae. It is found in areas within the Atlantic Forest in the municipalities of Rio de Janeiro and Teresópolis, Brazil.
Geoplana pulchella is a species of land planarian belonging to the subfamily Geoplaninae. It is found in areas of the Atlantic Forest within the state of Santa Catarina, such as in Blumenau, Paulo Lopes, and Alfredo Wagner, in Brazil.
Marion Liddell Fyfe was a New Zealand academic, specialising in taxonomy of planarians and other flatworms, the first woman zoology lecturer at the University of Otago, and the first woman to be elected to the Council of the Royal Society Te Apārangi.
Geoplanini is a tribe of land planarians in the subfamily Geoplaninae.
