Polymastia Echinus
''Polymastia echinus'' is a species of sea sponge belonging to the family Polymastiidae. It is only known from shallow subtidal habitats off Te HÄwere-a-Maki / Goat Island in the north of the North Island of New Zealand. This is an encrusting sponge with an extraordinary appearance. The sponge is always largely covered in sand, grit and fragments of shells apart from smooth, cylindrical, peach-coloured papillae up to 15 mm in height which are always free of such material. The specific name refers to this rather hedgehog A hedgehog is a spiny mammal of the subfamily Erinaceinae, in the eulipotyphlan family Erinaceidae.

Michelle Kelly-Borges
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 ...

Sea Sponge
Sponges, the members of the phylum Porifera (; meaning 'pore bearer'), are a basal animal clade as a sister of the diploblasts. They are multicellular organisms that have bodies full of pores and channels allowing water to circulate through them, consisting of jelly-like mesohyl sandwiched between two thin layers of cells. Sponges have unspecialized cells that can transform into other types and that often migrate between the main cell layers and the mesohyl in the process. Sponges do not have nervous, digestive or circulatory systems. Instead, most rely on maintaining a constant water flow through their bodies to obtain food and oxygen and to remove wastes. Sponges were first to branch off the evolutionary tree from the last common ancestor of all animals, making them the sister group of all other animals. Etymology The term ''sponge'' derives from the Ancient Greek word ( 'sponge'). Overview Sponges are similar to other animals in that they are multicellular, he ...

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 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'' * '' Proteleia'' * '' Pseudotrachya'' * '' Quasillina'' * '' Radiella'' * '' Ridleia'' * '' Sphaerotylus'' * '' Spinularia'' * ''Tentorium'' * '' Trachyteleia'' * ''Tylexocladus ''Tylexocladus'' is a genus of deep-water sea sponge belonging to the family Polymastiidae Polymastiidae is a family of demosponges found in oceans throughout the world.

Te HÄwere-a-Maki / Goat Island
Goat Island or Te HÄwere-a-Maki is a tiny island (approximately ) in New Zealand located close to the North Island coast, north of Auckland, northeast of Warkworth, and directly west of Little Barrier Island. It is within Cape Rodney-Okakari Point Marine Reserve, New Zealand's first marine reserve. History The island is spiritually significant to the local MÄori tribe, NgÄti Manuhiri, because their ancestral waka (canoe), '' MoekÄkara'', is said to have landed nearby. The Cape Rodney-Okakari Point Marine Reserve was established in 1975, making Goat Island and the surrounding waters a protected area. As well as being in a marine reserve, Goat Island is a scenic reserve. The University of Auckland has a research facility at Goat Island known as the Leigh Marine Laboratory headed by Professor John Montgomery. This will form the base for the University's new South Pacific Centre for Marine Science (SPCMS). Prime Minister Helen Clark launched the national and international ca ...

North Island
The North Island, also officially named Te Ika-a-MÄui, is one of the two main islands of New Zealand, separated from the larger but much less populous South Island by the Cook Strait. The island's area is , making it the world's 14th-largest island. The world's 28th-most-populous island, Te Ika-a-MÄui has a population of accounting for approximately % of the total residents of New Zealand. Twelve main urban areas (half of them officially cities) are in the North Island. From north to south, they are WhangÄrei, Auckland, Hamilton, Tauranga, Rotorua, Gisborne, New Plymouth, Napier, Hastings, Whanganui, Palmerston North, and New Zealand's capital city Wellington, which is located at the south-west tip of the island. Naming and usage Although the island has been known as the North Island for many years, in 2009 the New Zealand Geographic Board found that, along with the South Island, the North Island had no official name. After a public consultation, the board officially ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hedgehog
A hedgehog is a spiny mammal of the subfamily Erinaceinae, in the eulipotyphlan family Erinaceidae. There are seventeen species of hedgehog in five genera found throughout parts of Europe, Asia, and Africa, and in New Zealand by introduction. There are no hedgehogs native to Australia and no living species native to the Americas. However, the extinct genus ''Amphechinus'' was once present in North America. Hedgehogs share distant ancestry with shrews (family Soricidae), with gymnures possibly being the intermediate link, and they have changed little over the last fifteen million years. Like many of the first mammals, they have adapted to a nocturnal way of life. Their spiny protection resembles that of porcupines, which are rodents, and echidnas, a type of monotreme. Etymology The name ''hedgehog'' came into use around the year 1450, derived from the Middle English ''heyghoge'', from ''heyg'', ''hegge'' ("hedge"), because it frequents hedgerows, and ''hoge'', ''hogge'' ...

Polymastia (sponge)
''Polymastia'' is a genus of sea sponges containing about 30 species. These are small to large encrusting or dome-shaped sponges with a smooth surface having many teat-shaped projections (papillae). In areas of strong wave action, this 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.

Animals Described In 1997
Animals are multicellular, eukaryotic organisms in the biological kingdom Animalia. With few exceptions, animals consume organic material, breathe oxygen, are able to move, can reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of cells, the blastula, during embryonic development. Over 1.5 million living animal species have been described—of which around 1 million are insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology. Most living animal species are in Bilateria, a clade whose members have a bilaterally symmetric body plan. The Bilateria include the protostomes, containing animals such as nematodes, arthropods, flatworms, annelids and molluscs, and the deuterostomes, containing the echinoderms and ...

Taxa Named By Patricia Bergquist
In biology, a taxon (back-formation from ''Taxonomy (biology), 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 Taxonomic rank, 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 Linnaean taxonomy, system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard de Jussieu, Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of bio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
