Civifractura
''Civifractura'' is a monotypic genus of deep sea amphipods in the family, Alicellidae, first described in 2020 by Johanna Weston, Rachael Peart, and Alan Jamieson, which consists of the species ''Civifractura serendipia''. The species epithet, ''serendipia,'' refers to its serendipitous discovery. This species was found at a depth of 4932 m in the Wallaby-Zenith The zenith (, ) is an imaginary point directly "above" a particular location, on the celestial sphere. "Above" means in the vertical direction ( plumb line) opposite to the gravity direction at that location ( nadir). The zenith is the "high ... fracture zone of the Indian Ocean.

Alan Jamieson
Alan J. Jamieson is a Scottish marine biologist, engineer, explorer and author, best known for his deep-sea exploration and study of life at the deepest places in the oceans. He is known for extensive use of deep-sea landers to establish the maximum depth and community dynamics of many organismal groups, as well as the discovery of many new species and highlighting the presence of anthropogenic impacts at full ocean depth. During the Five Deeps Expedition, and follow on expeditions in 2020, he completed various dives in a manned submersible to some of the deepest places in the world. He has published over 100 scientific papers and participated in 65 deep-sea expeditions. Education and career Jamieson was born in Scotland and grew up in Largs in Ayrshire, and then Longniddry in East Lothian. He attended Preston Lodge High School in Prestonpans. From 1995 to 1999, he obtained a BSc Honours degree in Design for Industry at Robert Gordon University's Gray's School of Art in Aberdee ...

Alicellidae
Alicellidae is a family of amphipod crustaceans, which live as scavengers in the deep sea (at depths of ), often in association with hydrothermal vents. The family includes the following genera: *''Alicella ''Alicella gigantea'' is the largest species of amphipod ever observed, with some individuals reaching up to long. The average length of A. gigantea ranges from 72.5 to 141.0 millimeters, and its weight ranges from 4.2 to 45 grams Comparativel ...''

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. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. '' Panthera leo'' (lion) and '' Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should c ...

Amphipoda
Amphipoda is an order of malacostracan crustaceans with no carapace and generally with laterally compressed bodies. Amphipods range in size from and are mostly detritivores or scavengers. There are more than 9,900 amphipod species so far described. They are mostly marine animals, but are found in almost all aquatic environments. Some 1,900 species live in fresh water, and the order also includes the terrestrial sandhoppers such as '' Talitrus saltator''. Etymology and names The name ''Amphipoda'' comes, via New Latin ', from the Greek roots 'on both/all sides' and 'foot'. This contrasts with the related Isopoda, which have a single kind of thoracic leg. Particularly among anglers, amphipods are known as ''freshwater shrimp'', ''scuds'', or ''sideswimmers''. Description Anatomy The body of an amphipod is divided into 13 segments, which can be grouped into a head, a thorax and an abdomen. The head is fused to the thorax, and bears two pairs of antennae and one pair of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zenith Plateau
The Zenith Plateau is a large bathymetric high in the Indian Ocean, located about west-northwest of the Wallaby Plateau, west-northwest of Carnarvon, Western Australia, and north-west of Perth, Western Australia. The summit of the Zenith Plateau lies below sea level and its base is at about below sea level. It is about long and wide. In the east, the Zenith Plateau is separated from the Wallaby (Cuvier) Plateau by a wide, north to northeast-trending bathymetric trough.British Oceanographic Data Centre, 2003, ''GEBCO Digital Atlas.''

Gammaridea
Gammaridea is one of the suborders of the order Amphipoda, comprising small, shrimp-like crustaceans. Until recently, in a traditional classification, it encompassed about 7,275 (92%) of the 7,900 species of amphipods described by then, in approximately 1,000 genera, divided among around 125 families. That concept of Gammaridea included almost all freshwater amphipods, while most of the members still were marine. The group is however considered paraphyletic, and is under deconstruction by the amphipod taxonomists J. Lowry and A. Myers. In 2003 they moved several families from Gammaridea to join members of the former Caprellidea in a new suborder Corophiidea.A. A. Myers & J. K. Lowry (2003). "A phylogeny and a new classification of the Corophiidea Leach, 1814 (Amphipoda)". Journal of Crustacean Biology 23 (2): 443–485. doi:10.1651/0278-0372 Further, in 2013 another large suborder Senticaudata was established, which now encompasses much of the original Gammaridea, particularl ...

Monotypic Crustacean Genera
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, ''Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda.'' ...
