Soleneiscus Hispidus
''Soleneiscus hispidus'' is a species of calcareous sponge in the family Dendyidae. The sponge was first described in 1931 by Holger Valdemar Brøndsted as ''Leucosolenia hispida''. According to the Australian Faunal Directory it is known only from the Australian Antarctic Territories, where it has been found at a depth of 350–385 m on the Wilhelm II Coast Wilhelm may refer to: People and fictional characters * William Charles John Pitcher, costume designer known professionally as "Wilhelm" * Wilhelm (name), a list of people and fictional characters with the given name or surname Other uses * Moun ....

Holger Valdemar Brøndsted
Holger Valdemar Brøndsted (1893–1977) was a Danish zoologist, teacher and writer. He earned his first degree from Aarhus University, and then studied natural sciences at the University of Copenhagen. This led to his working as an assistant to Professor Johan Erik Vesti Boas at the Agricultural University's zoological laboratory, as both a teacher and researcher. Following his marriage in 1919, he went to work at Birkerød State School in 1920, initially working as a part-time teacher, but 1921 as an assistant professor. This led to his writing several popular biology books. While teaching, he resumed his scientific studies, first at the Carlsberg Foundation's Biological Institute with Albert Fischer, and later at Stockholm University (1934-1936), where he earned his doctorate with the thesis, ''Entwicklungsphysiologische Studien über Spongilla lacustris'' (Studies of the developmental physiology of '' Spongilla lacustris''). His interest in developmental physiology led to a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Calcareous Sponge
The calcareous sponges of class Calcarea are members of the animal phylum Porifera, the cellular sponges. They are characterized by spicules made of calcium carbonate in the form of calcite or aragonite. While the spicules in most species have three points, in some species they have either two or four points. Biology All sponges in this class are strictly marine, and, while they are distributed worldwide, most are found in shallow tropical waters. Like nearly all other sponges, they are sedentary filter feeders. All three sponge body plans are represented within class Calcarea : asconoid, syconoid, and leuconoid. Typically, calcareous sponges are small, measuring less than in height, and drab in colour. However, a few brightly coloured species are also known. Calcareous sponges vary from radially symmetrical vase-shaped body types to colonies made up of a meshwork of thin tubes, or irregular massive forms. The skeleton has either a mesh or honeycomb structure. Classifica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Australian Faunal Directory
The Australian Faunal Directory (AFD) is an online catalogue of taxonomic and biological information on all animal species known to occur within Australia. It is a program of the Department of Climate Change, Energy, the Environment and Water of the Government of Australia. By May 12, 2021, the Australian Faunal Directory has collected information about 126,442 species and subspecies In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (morphology), but that can successfully interbreed. Not all species .... It includes the data from the discontinued ''Zoological Catalogue of Australia'' and is regularly updated. Started in the 1980s, it set a goal to compile a "list of all Australian fauna including terrestrial vertebrates, ants and marine fauna" and create an "Australian biotaxonomic information system".''Commonwealth Record'', Volume 5, Issues 26-34, p. 1 ...

Kaiser Wilhelm II Land
Kaiser Wilhelm II Land is a part of Antarctica lying between Cape Penck at 87° 43'E and Cape Filchner at 91° 54'E. Princess Elizabeth Land is located to the west, and Queen Mary Land to the east. The area is claimed by Australia as part of the Australian Antarctic Territory, but like other territorial claims in Antarctica this is not universally recognized. Exploration The area was discovered on 22 February 1902, during the ''Gauss'' expedition of 1901–1903 led by Arctic veteran and geologist Erich von Drygalski. Drygalski named it after the sitting Kaiser Wilhelm II who had funded the expedition with 1.2 million Goldmarks. The expedition also discovered the Gaussberg, a extinct volcano, which was named after mathematician and physicist Carl Friedrich Gauss Johann Carl Friedrich Gauss (; german: Gauß ; la, Carolus Fridericus Gauss; 30 April 177723 February 1855) was a German mathematician and physicist who made significant contributions to many fiel ...
