Stomolophus Fritillarius
''Stomolophus'' is a genus of true jellyfish from the West Atlantic and Pacific. It is the only genus in the monotypic family Stomolophidae. Formerly, Nomura's jellyfish (''Nemopilema nomurai'') was also included in this genus, but has now been reclassified to the family Rhizostomatidae.

Species
In biology, a species is the basic unit of 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 produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, 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 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 specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scyphozoa
The Scyphozoa are an exclusively marine class of the phylum Cnidaria, referred to as the true jellyfish (or "true jellies"). The class name Scyphozoa comes from the Greek word ''skyphos'' (), denoting a kind of drinking cup and alluding to the cup shape of the organism. Scyphozoans have existed from the earliest Cambrian to the present. Biology Most species of Scyphozoa have two life-history phases, including the planktonic medusa or polyp form, which is most evident in the warm summer months, and an inconspicuous, but longer-lived, bottom-dwelling polyp, which seasonally gives rise to new medusae. Most of the large, often colorful, and conspicuous jellyfish found in coastal waters throughout the world are Scyphozoa. They typically range from in diameter, but the largest species, ''Cyanea capillata'' can reach across. Scyphomedusae are found throughout the world's oceans, from the surface to great depths; no Scyphozoa occur in freshwater (or on land). As medusae, they eat a ...

Monotypic Taxon
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 ...

Rhizostomatidae
Rhizostomatidae is a family of cnidarians in the class Scyphozoa. Genera and species According to the World Register of Marine Species, 11 extant species are in four extant genera within this family: *Genus ''Eupilema'' **'' Eupilema inexpectata'' Pages, Gili & Bouillon, 1992 *Genus '' Nemopilema'' **'' Nemopilema nomurai'' Kishinouye, 1922 *Genus '' Rhizostoma'' Cuvier, 1800 **'' Rhizostoma luteum'' (Quoy & Gaimard, 1827) **'' Rhizostoma octopus'' (Linnaeus, 1758) **'' Rhizostoma pulmo'' (Macri, 1778) *Genus ''Rhopilema'' Haeckel, 1880 **''Rhopilema esculentum'' Kishinouye, 1891 **''Rhopilema hispidum'' **'' Rhopilema nomadica'' **'' Rhopilema rhopalophora'' (Haeckel) **''Rhopilema rhopalophorum'' Haeckel, 1880 **''Rhopilema verrilli'' Extinct taxa * Genus †''Essexella'' * Genus †'' Simplicibrachia'', is known from fossils in the Ypresian In the geologic timescale the Ypresian is the oldest age or lowest stratigraphic stage of the Eocene.

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 ...

Stomolophus Meleagris
The cannonball jellyfish (''Stomolophus meleagris''), also known as the cabbagehead jellyfish, is a species of jellyfish in the family Stomolophidae. Its common name derives from its similarity to a cannonball in shape and size. Its dome-shaped bell can reach in diameter and, in the Atlantic and Gulf of Mexico, the rim is sometimes colored with brown pigment. In the Pacific, this jellyfish can also have a blue pigment. Underneath the body is a cluster of oral arms that extend out around the mouth. These arms function in propulsion and as an aid in catching prey. Cannonballs are prominent from North America's eastern seaboard all the way to Brazil, but are also found in parts of the Pacific. Habitat They have been found in Pacific Ocean (South China Sea to Sea of Japan, and California to Ecuador) and the mid-west Atlantic Ocean (New England to Brazil). They are common on the southeastern coast of the United States, including the Gulf Coast. On the southeast coast they are extrem ...
