Carukia Barnesi
''Carukia barnesi'' is an extremely venomous jellyfish found near Australia. Stings can result in Irukandji syndrome, and this species is commonly known as Irukandji jellyfish, although this name does not distinguish it from other Irukandji jellyfish such as ''Malo kingi''. A mature ''C. barnesi's'' bell is only in height. It has four contractile tentacles, one extending from each bottom "corner" of its bell, ranging in length from . The species was discovered by Jack Barnes of Cairns, Australia. While on an exploration mission aimed at determining the reason for Irukandji syndrome, Barnes allowed himself, a lifeguard, and his 9-year-old son to be stung by the jellyfish. ''Carukia barnesi'' is a soft-bodied marine organism. This species falls within the Medusozoa subphylum and the Cubozoa class. It is a type of "box jellyfish" that is known for producing potent venom and is known for inflicting the Irukandji syndrome. Threat to Humans: The Irukandji syndrome was first discove ...

Box Jellyfish
Box jellyfish (class Cubozoa) are cnidarian invertebrates distinguished by their box-like (i.e. cube-shaped) body. Some species of box jellyfish produce potent venom delivered by contact with their tentacles. Stings from some species, including ''Chironex fleckeri'', ''Carukia barnesi'', ''Malo kingi'', and a few others, are extremely painful and often fatal to humans. Taxonomy and systematics At least 51 species of box jellyfish were known as of 2018. These are grouped into two orders and eight families. A few new species have since been described, and it is likely that additional undescribed species remain. Cubozoa represents the smallest cnidarian class with approximately 50 species.

Carukiidae
Carukiidae is a family of box jellyfish within the Cubozoa class. Carukiidae can be easily classified by their lack of cirri clumps inside the cubozoan stomach, as well as the size and the placement of their nematocysts. Carukiidae use nematocysts as a defense mechanism; they releases a venom from the tips of their nematocysts, producing the Irukandji syndrome. Even though positions of spines on the shaft of the Carukiidae cause illness, there are areas on the body that do not. The rhopalial niche openings, which discern light, do not incur any illness. The Carukiidae also have non-venomous rhopaliar horns, which are imperceptive in function and located above the rhopalial niches. Irukandji syndrome triggered by Carukiidae requires immediate medical attention. In the event that it goes untreated in humans, cardiac arrest is a potentially deadly consequence.

Carukia Shinju
''Carukia shinju'' is a small and venomous jellyfish found off the waters of northwestern Australia. Specifically, located offshore of the coasts of Australian states including Queensland, The Northern Territory, Western Australia and South Australia. Stings can result in Irukandji syndrome Irukandji syndrome is a condition that results from envenomation by certain box jellyfish. In rare instances the sting may result in cardiac arrest and death. The most common jellyfish involved is the ''Carukia barnesi'', a species of Irukandji .... The mechanisms of actions of their toxins are not completely understood, but evidence shows they include modulation of neuronal sodium channels leading to large releases of endogenous catecholamines that can lead to possible stress-induced cardiomyopathy.

Ronald Vernon Southcott
Ronald Vernon Southcott (15 May 1918 in Adelaide – 9 April 1998) was an Australian medical zoologist specializing in Acari, mites and ticks. Biography After finishing school at St Peter's College, Adelaide Southcott started working on mites, or the acari, at the age of 16 with Herbert Womersley the acarologist at the South Australian Museum. Womersley described and named the trombidiid mite, which Southcott had collected on a cycling trip in the hills near Adelaide in 1934, ''Microtrombidium southcotti'', after Southcott. Southcott considered that act by Herb Womersley, "hooked me on mites". Southcott studied medicine at the University of Adelaide where he graduated in 1941. Southcott then served in the Australian Army Medical Corps from 1942 to 1946. While he was stationed at Cairns he started working on the taxonomy and medical effects of jellyfish, the subject for which he was later to become famous. His more than 230 papers on the red mites include a classic revision of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), 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 taxonomy (biology), 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 ...

World Register Of Marine Species
The World Register of Marine Species (WoRMS) is a taxonomic database that aims to provide an authoritative and comprehensive list of names of marine organisms. Content The content of the registry is edited and maintained by scientific specialists on each group of organism. These taxonomists control the quality of the information, which is gathered from the primary scientific literature as well as from some external regional and taxon-specific databases. WoRMS maintains valid names of all marine organisms, but also provides information on synonyms and invalid names. It is an ongoing task to maintain the registry, since new species are constantly being discovered and described by scientists; in addition, the nomenclature and taxonomy of existing species is often corrected or changed as new research is constantly being published. Subsets of WoRMS content are made available, and can have separate badging and their own home/launch pages, as "subregisters", such as the ''World List of ...
