Cymbastela Stipitata
''Cymbastela stipitata'' is a species of marine sponge in the family Axinellidae. The sponge was first described in 1967 by Patricia Bergquist and Catherine Tizard as ''Pseudaxinyssa stipitata'', but was assigned to the new genus, ''Cymbastela'', in 1992 by John Hooper and Patricia Bergquist. It is found in Australia's coastal waters, from the Gulf of Carpentaria to the north west coasts of Western Australia Western Australia (commonly abbreviated as WA) is a state of Australia occupying the western percent of the land area of Australia excluding external territories. It is bounded by the Indian Ocean to the north and west, the Southern Ocean to th .... It is a sessile filter-feeder, found generally in intertidal waters on coral reefs at depths up to 19 m.

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 Auckla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Catherine Tizard
Dame Catherine Anne Tizard (née Maclean; 4 April 1931 – 31 October 2021) was a New Zealand politician who served as mayor of Auckland City from 1983 to 1990, and the 16th governor-general of New Zealand from 1990 to 1996. She was the first woman to hold either office. Personal life and early career Catherine Anne Maclean was born in Auckland on 4 April 1931 to Scottish immigrants Neil and Helen Maclean, and grew up in Waharoa, near Matamata, Waikato. Her father worked at the local dairy factory. She attended Matamata College, gaining a University Bursary in her final year, 1948. In 1949 Catherine enrolled at Auckland University College, studying zoology. While at university, she met Bob Tizard, then president of the Auckland University Students Association. On their second date, Bob told Catherine he was "going into politics. And I'm going to marry you." They married in 1951 and had four children; their daughter Judith is also a politician.

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Axinellidae
Axinellidae is a family of sponges in the order Axinellida. This family includes some photo-synthetic sponges that occur throughout the world's coral reefs. They are amongst the more common sponges seen in the aquarium trade but are usually not successful species in captivity and not ones that thrive in the small household tank environment. They are common throughout the Indian Ocean and the Pacific Ocean coral reefs. Species which derive their nutrition from sunlight must stay fairly close to the surface in order for their zooxanthellae to synthesize light into the sugars these sponges use to survive. Genera There are ten genera: * ''Axinella'' Schmidt, 1862 * ''Cymbastela'' Hooper & Bergquist, 1992 * ''Dragmacidon'' Hallmann, 1917 * ''Dragmaxia'' Hallmann, 1916 * ''Ophiraphidites'' Carter, 1876 * ''Pararhaphoxya'' Burton, 1934 * ''Phycopsis (sponge), Phycopsis'' Carter, 1883 * ''Pipestela'' Alvarez, Hooper & van Soest, 2008 * ''Ptilocaulis'' Carter, 1883 * ''Reniochalina'' Lend ...

Gulf Of Carpentaria
The Gulf of Carpentaria (, ) is a large, shallow sea enclosed on three sides by northern Australia and bounded on the north by the eastern Arafura Sea (the body of water that lies between Australia and New Guinea). The northern boundary is generally defined as a line from Slade Point, Queensland (the northwestern corner of Cape York Peninsula) in the northeast, to Cape Arnhem on the Gove Peninsula, Northern Territory (the easternmost point of Arnhem Land) in the west. At its mouth, the Gulf is wide, and further south, . The north-south length exceeds . It covers a water area of about . The general depth is between and does not exceed . The tidal range in the Gulf of Carpentaria is between . The Gulf and adjacent Sahul Shelf were dry land at the peak of the last ice age 18,000 years ago when global sea level was around below its present position. At that time a large, shallow lake occupied the centre of what is now the Gulf. The Gulf hosts a submerged coral reef provinc ...

Western Australia
Western Australia (commonly abbreviated as WA) is a state of Australia occupying the western percent of the land area of Australia excluding external territories. It is bounded by the Indian Ocean to the north and west, the Southern Ocean to the south, the Northern Territory to the north-east, and South Australia to the south-east. Western Australia is Australia's largest state, with a total land area of . It is the second-largest country subdivision in the world, surpassed only by Russia's Sakha Republic. the state has 2.76 million inhabitants percent of the national total. The vast majority (92 percent) live in the south-west corner; 79 percent of the population lives in the Perth area, leaving the remainder of the state sparsely populated. The first Europeans to visit Western Australia belonged to the Dutch Dirk Hartog expedition, who visited the Western Australian coast in 1616. The first permanent European colony of Western Australia occurred following the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
