It is a deep-ocean species found on muddy substrates at depths of over 3000 m in the Ross Sea The Ross Sea is a deep bay of the Southern Ocean in Antarctica, between Victoria Land and Marie Byrd Land and within the Ross Embayment, and is the southernmost sea on Earth.

Polymastiidae
Polymastiidae is a family of demosponges found in oceans throughout the world. It is the only family in the monotypic order Polymastiida. A useful diagnostic characteristic of members of this family is the presence of numerous surface Papilla (sponge), papillae although this feature is shown by some other sponges. Genera The following genera are recognised in the family Polymastiidae * ''Acanthopolymastia'' * ''Astrotylus'' * ''Atergia'' * ''Koltunia'' * ''Polymastia (sponge), Polymastia'' * ''Proteleia'' * ''Pseudotrachya'' * ''Quasillina'' * ''Radiella'' * ''Ridleia'' * ''Sphaerotylus'' * ''Spinularia'' * ''Tentorium (sponge), Tentorium'' * ''Trachyteleia'' * ''Tylexocladus'' * ''Weberella'' ReferencesNorth East Atlantic Taxa*WoRMS - Polymastiidae Gray, 1867 Polymastiidae, {{demosponge-stub ...

Acanthopolymastia Bathamae
''Acanthopolymastia bathamae'' is a species of sea sponge belonging to the family Polymastiidae. It is only known from the Papanui Submarine Canyon off Dunedin, South Island The South Island, also officially named , is the larger of the two major islands of New Zealand in surface area, the other being the smaller but more populous North Island. It is bordered to the north by Cook Strait, to the west by the Tasma ..., New Zealand. This is a small, cream-coloured hemispherical sponge up to 8 mm in diameter. Its texture is soft and velvety with a single central papilla up to 7 mm in height.

Michelle Kelly (marine Scientist)
Michelle Kelly (born 1961), also known as Michelle Kelly-Borges, is a New Zealand scientist who specialises in sponges, their chemistry, their evolution, taxonomy, systematics, and ecology. Early life and education Born in Otago in 1961, Kelly lived in Papua New Guinea with her family from 1970 to 1980, and was educated at The Correspondence School. From 1980, she studied at the University of Auckland, and completed a Bachelor of Science degree in 1983, and a Master of Science with honours in 1987. Her masterate research, supervised by Patricia Bergquist, was an investigation of the systematics and ecology of the sponges of Motupore Island in Papua New Guinea. The title of that thesis was ''Systematics and ecology of the sponges of Motupore Island, Papua New Guinea''. She then earned a PhD at the University of Auckland in 1991 under the joint supervision of Patricia and Peter Bergquist, with a thesis entitled, ''The order Hadromerida (Porifera: Demospongiae), taxonomy and rela ...

Patricia Bergquist
Dame Patricia Rose Bergquist (née Smyth, 10 March 1933 – 9 September 2009) was a New Zealand zoologist who specialised in anatomy and taxonomy. At the time of her death, she was professor emerita of zoology and honorary professor of anatomy with radiology at the University of Auckland. Early life, family and education Born Patricia Rose Smyth in the Auckland suburb of Devonport on 10 March 1933, Bergquist was the daughter of William Smyth, an electrician, and Bertha Ellen ( Penny) Smyth, a homemaker. She had a younger brother Norman and a sister Catherine. She was educated at Devonport Primary School, and then Takapuna Grammar School where she was dux in her final year. She then began studying at Auckland University College in 1950, graduating MSc with first-class honours in botany in 1956; the title of her master's thesis was ''Contributions to the study of the loxsomaceae''. After completing a second MSc equivalent in zoology, she undertook doctoral studies at Auckland ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. '' Panthera leo'' (lion) and '' Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should c ...

Demosponge
Demosponges (Demospongiae) are the most diverse class in the phylum Porifera. They include 76.2% of all species of sponges with nearly 8,800 species worldwide (World Porifera Database). They are sponges with a soft body that covers a hard, often massive skeleton made of calcium carbonate, either aragonite or calcite. They are predominantly leuconoid in structure. Their " skeletons" are made of spicules consisting of fibers of the protein spongin, the mineral silica, or both. Where spicules of silica are present, they have a different shape from those in the otherwise similar glass sponges. Some species, in particular from the Antarctic, obtain the silica for spicule building from the ingestion of siliceous diatoms. The many diverse orders in this class include all of the large sponges. Most are marine dwellers, but one order ( Spongillida) live in freshwater environments. Some species are brightly colored, with great variety in body shape; the largest species are ...

Taxa Named By Patricia Bergquist
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
