(2000). Thalassianthidae. http://tolweb.org/Thalassianthidae/18326 Research has shown that three species of sea anemones belonging to the family Thalassianthidae - (''Cryptodendrum adhaesivum'', ''Heterodactyla hemprichii'' and ''Thalassianthus aster'') - contain type 2 sodium channel peptide toxins capable of causing lethality to freshwater crabs. In addition, high molecular weight toxins appear to be a new type of toxin in the Thalassianthidae family of sea anemone Sea anemones are a group of predation, predatory marine invertebrates of the order ...

Heterodactyla Hemprichii
''Heterodactyla hemprichii'' is a species of sea anemone in the family Thalassianthidae, and was first formally described in 1834 by Christian Gottfried Ehrenberg. This sea anemone does not host any varieties of clownfish, but has been associated with some species of commensal anemone shrimp Hippolytidae is a family of cleaner shrimp, also known as broken-back shrimp or anemone shrimp. The term "broken-back shrimp" also applies to the genus ''Hippolyte'' in particular and "cleaner shrimp" is sometimes applied exclusively to ''Lysmata ....Tree of Life. (2000).

Wilhelm Hemprich
Wilhelm Friedrich Hemprich (24 June 1796 – 30 June 1825) was a German naturalist and explorer. Hemprich was born in Glatz (Kłodzko), Prussian Silesia, and studied medicine at Breslau and Berlin. It was in Berlin that he became friends with Christian Gottfried Ehrenberg, the two men sharing an interest in natural history. Hemprich lectured at Berlin University on comparative physiology, and wrote ''Grundriss der Naturgeschichte'' (Compendium of Natural History) (1820). In his spare time he studied reptiles and amphibians at the zoological museum under Hinrich Lichtenstein. In 1820 Hemprich and Ehrenberg were invited to serve as naturalists on a primarily archeological expedition to Egypt, led by Prussian General von Minutoli. The two naturalists were sponsored by the Berlin Academy. In March 1821 they separated from the main party and travelled up the river Nile to Dongola, the capital of Nubia. They spent the next two years studying the natural history of that part of Egy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Christian Gottfried Ehrenberg
Christian Gottfried Ehrenberg (19 April 1795 – 27 June 1876) was a German naturalist, zoologist, comparative anatomist, geologist, and microscopist. Ehrenberg was an evangelist and was considered to be of the most famous and productive scientists of his time. Early collections The son of a judge, Christian Gottfried Ehrenberg was born in Delitzsch, near Leipzig. He first studied theology at the University of Leipzig, then medicine and natural sciences in Berlin and became a friend of the famous explorer Alexander von Humboldt. In 1818, he completed his doctoral dissertation on fungi, ''Sylvae mycologicae Berolinenses.'' In 1820–1825, on a scientific expedition to the Middle East with his friend Wilhelm Hemprich, he collected thousands of specimens of plants and animals. He investigated parts of Egypt, the Libyan Desert, the Nile valley and the northern coasts of the Red Sea, where he made a special study of the corals. Subsequently, parts of Syria, Arabia and Abyss ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sea Anemone
Sea anemones are a group of predation, predatory marine invertebrates of the order (biology), order Actiniaria. Because of their colourful appearance, they are named after the ''Anemone'', a terrestrial flowering plant. Sea anemones are classified in the phylum Cnidaria, class Anthozoa, subclass Hexacorallia. As cnidarians, sea anemones are related to corals, jellyfish, tube-dwelling anemones, and ''hydra (genus), Hydra''. Unlike jellyfish, sea anemones do not have a Jellyfish#Life history and behavior, medusa stage in their life cycle. A typical sea anemone is a single polyp (zoology), polyp attached to a hard surface by its base, but some species live in soft sediment, and a few float near the surface of the water. The polyp has a columnar trunk topped by an oral disc with a ring of tentacles and a central mouth. The tentacles can be retracted inside the body cavity or expanded to catch passing prey. They are armed with cnidocytes (stinging cells). In many species, additional n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hexacorallia Genera
Hexacorallia is a class of Anthozoa comprising approximately 4,300 species of aquatic organisms formed of polyps, generally with 6-fold symmetry. It includes all of the stony corals, most of which are colonial and reef-forming, as well as all sea anemones, and zoanthids, arranged within five extant orders. The hexacorallia are distinguished from another class of Anthozoa, Octocorallia, in having six or fewer axes of symmetry in their body structure; the tentacles are simple and unbranched and normally number more than eight. These organisms are formed of individual soft polyps which in some species live in colonies and can secrete a calcite skeleton. As with all Cnidarians, these organisms have a complex life cycle including a motile planktonic phase and a later characteristic sessile phase. Hexacorallia also include the significant extinct order of rugose corals. Phylogeny Hexacorallia is considered to be monophyletic, that is all contained species are descended from a common ...

Taxa Named By Christian Gottfried Ehrenberg
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 intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
