Gert Wörheide
Gert Wörheide is a German marine biologist who works mainly on marine invertebrates. He earned his doctorate in geobiology from Georg-August-Universität, following this with a post-doctorate at Queensland Museum (1998-2002), where he worked with John Hooper on sponges, a collaboration which continues. Following his postdoctorate in Queensland, Wörheide returned to Germany to become a junior professor in molecular geobiology at Georg-August-Universität (2002-2008), and in October 2008 was appointed Chair of Geobiology & Paleontology at Ludwig-Maximilians-Universität (University of Munich) (his current position), where he continues to work on evolution and genomics, and all things pertaining to marine invertebrates. His most cited paper with 559 citations (at 2020-09-29) is "Resolving Difficult Phylogenetic Questions: Why More Sequences Are Not Enough".

John Hooper (marine Biologist)
John N.A. Hooper is an Australian marine biologist and writer on science. He is the current Head of Biodiversity & Geosciences Programs at the Queensland Museum. His research has included studying the possible medical benefits of marine sponges, including beta blockers for heart disease Cardiovascular disease (CVD) is a class of diseases that involve the heart or blood vessels. CVD includes coronary artery diseases (CAD) such as angina and myocardial infarction (commonly known as a heart attack). Other CVDs include stroke, hea ..., and for compounds to combat illnesses like gastro-intestinal disease and cancer. In 2007 he was a member of the Discussion Panel On Marine Genetic Resources for the eighth annual United Nations Informal Consultative Process for Oceans and the Law of the Sea (UNICPOLOS).

Species
In biology, a species is the basic unit of Taxonomy (biology), 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 reproduction, produce Fertility, fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), 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 binomial nomenclature, 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 specifi ... [...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. Classificat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Clathrina
''Clathrina'' is a genus of calcareous sponge in the family Clathrinidae. Several species formerly in ''Clathrina'' were transferred to the newly erected genera ''Arturia'', '' Ernstia'', '' Borojevia'', and '' Brattegardia'' in 2013. The name is derived from the Latin word "''clathratus''" meaning "latticed". Description Species of ''Clathrina'' have a tubular organization as all species of the family Clathrinidae, with the cormus composed of anastomosed tubes. The skeleton contains spicules in the form of triactines and/or tetractines, sometimes with diactines, tripods and tetrapods as well. The choanoderm is usually flat, never forming folds when the sponge is extended. Species There are 68 species assigned to ''Clathrina''. * ''Clathrina angraensis'' Azevedo & Klautau, 2007 * ''Clathrina antofagastensis'' Azevedo, Hajdu, Willenz & Klautau, 2009 * '' Clathrina aphrodita'' Azevedo, Cóndor-Luján, Willenz, Hajdu, Hooker & Klautau, 2015 * ''Clathrina arabica'' (Miklucho-M ...

Animals Described In 1999
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 ...

Sponges Of Australia
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, het ...

Taxa Named By John Hooper (marine Biologist)
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 intr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
