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 ...

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opi ...

Catostylidae
Catostylidae is a family of jellyfish. Members of this family are characterized by their thick, sausage-like oral arms. Description Members of the family Catostylidae are small marine jellyfish with domed bells. The eight short oral arms are broad and three-sided. There is a network of branching canals linked with the primary ring canal, but these are not joined to the gastrovascular cavity except through the sixteen or thirty two radial canals. Some of these radial canals do not extend to the edge of the bell. There are eight sense organs, known as rhopalia, which have canals extending to the margin of the bell. These jellyfish swim in jerks by contracting their circular and radial muscles, which decreases the volume of water enclosed under the bell, before relaxing them again and repeating the sequence. They have no control over the direction of locomotion and drift with the currents and tides. Genera * '' Acromitoides'' :* '' Acromitoides purpurus'' (Mayer, 1910) :* '' Acromi ...

Catostylus Mosaicus
The jelly blubber (''Catostylus mosaicus''), also known as the blue blubber jellyfish, is a species of jellyfish from coastal regions in the Indo-Pacific. It is the most commonly encountered jellyfish along the Australian eastern coast and large swarms sometimes appear in estuarine waters. Description In Sydney waters, the jelly blubber's large bell is a creamy white or brown colour, but farther north in Australia it is usually blue. The colours are derived from symbiotic algal plant cells within the body of the jellyfish. There is no obvious mouth on the underside, but there are small openings on each arm, through which food is passed to the stomach. The tentacles also have stinging cells that can capture tiny crustaceans and other plankton. It can grow up to 35cm across. The sting can be painful but generally poses no serious risk to humans. Distribution and habitat This jellyfish is found in coastal parts of the Indo-Pacific. In Australia, it occurs off the coasts of Qu ...

Catostylus Tagi
''Catostylus tagi'' is a species of jellyfish from warmer parts of the East Atlantic Ocean and since the 2000s also found in the Mediterranean Sea. It is the only member of the family Catostylidae that is found in Europe.Parracho, T.; and Z. Morais (2015). Catostylus tagi: partial rDNA sequencing and characterisation of nematocyte structures using two improvements in jellyfish sample preparation. J Venom Anim Toxins Incl Trop Dis. 21: 40. It has collagen in its bell which is currently being researched to see if it has biomedical uses as an intercellular matrix. The species is named after the Tagus river. Description Typical ''Catostylus'' with chunky appendages and tentacle to go with each. This jellyfish has a sting that causes light pain and a skin rash, but generally poses no serious threat. It is up to in bell diameter, but a more typical size is in diameter and in weight. Its colour is variable and can be blue-white, cream, brown, or off-white. The exumbrellar grooves ar ...
