Nudibranch
Nudibranchs () are a group of soft-bodied marine gastropod molluscs which shed their shells after their larval stage. They are noted for their often extraordinary colours and striking forms, and they have been given colourful nicknames to match, such as "clown", "marigold", "splendid", "dancer", "dragon", or "sea rabbit". Currently, about 3,000 valid species of nudibranchs are known.Ocean Portal (2017)A Collage of Nudibranch Colors Smithsonian National Museum of Natural History. Retrieved 17 April 2018. The word "nudibranch" comes from the Latin "naked" and the Ancient Greek () "gills". Nudibranchs are often casually called sea slugs, as they are a family of opistobranchs (sea slugs), within the phylum Mollusca (molluscs), but many sea slugs belong to several taxonomic groups which are not closely related to nudibranchs. A number of these other sea slugs, such as the photosynthetic '' Sacoglossa'' and the colourful Aglajidae, are often confused with nudibranchs. Distributi ...

Dendronotidae
Dendronotidae is a family of sea slugs, nudibranchs, marine gastropod mollusks in the superfamily Dendronotoidea. This family is within the clade Cladobranchia (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005).

Notobryon Wardi
''Notobryon wardi'', the iridescent nudibranch, is a species of scyllid nudibranch, and is found in South Africa. It is a marine gastropod mollusc in the family Scyllaeidae.Branch, G.M., Branch, M.L, Griffiths, C.L. and Beckley, L.E. 2010. ''Two Oceans: a guide to the marine life of southern Africa'' Distribution This species is found around the South African coast from Elands Bay to Jeffreys Bay. It is usually found inter-tidally but has been found to 20 m. Description ''Notobryon wardi'' is a medium-sized (up to 50 mm) smooth-bodied nudibranch.

Dendronotus Albus
''Dendronotus albus'' is a species of sea slug, a dendronotid nudibranch, a shell-less marine gastropod mollusc in the family Dendronotidae.Bouchet, P. (2015)''Dendronotus albus''.In: MolluscaBase (2015). Accessed through: World Register of Marine Species on 2016-01-26. Distribution This species was described from shallow water at Point Pinos, Monterey Bay, California, United States. It has been reported from the west coast of North America from Alaska to Baja California, Mexico. Taxonomic history Robilliard correctly recognised that there were two species of ''Dendronotus'' in the NE Pacific and described ''Dendronotus diversicolor'' as a new species. ''D. albus'' and ''D. diversicolor'' were synonymised by Stout et al., 2010, probably because the specimens they studied did not include both species. In fact Robilliard consistently used the name ''D. albus'' for '' Dendronotus robilliardi'' and redescribed the true ''D. albus'' as ''D. diversicolor''.Korshunova T., Sanamyan ...

Taxonomy (biology)
In biology, taxonomy () is the scientific study of naming, defining ( circumscribing) and classifying groups of biological organisms based on shared characteristics. Organisms are grouped into taxa (singular: taxon) and these groups are given a taxonomic rank; groups of a given rank can be aggregated to form a more inclusive group of higher rank, thus creating a taxonomic hierarchy. The principal ranks in modern use are domain, kingdom, phylum (''division'' is sometimes used in botany in place of ''phylum''), class, order, family, genus, and species. The Swedish botanist Carl Linnaeus is regarded as the founder of the current system of taxonomy, as he developed a ranked system known as Linnaean taxonomy for categorizing organisms and binomial nomenclature for naming organisms. With advances in the theory, data and analytical technology of biological systematics, the Linnaean system has transformed into a system of modern biological classification intended to reflect the ...

Superfamily (zoology)
In biological classification, taxonomic rank is the relative level of a group of organisms (a taxon) in an ancestral or hereditary hierarchy. A common system consists of species, genus, family, order, class, phylum, kingdom, domain. While older approaches to taxonomic classification were phenomenological, forming groups on the basis of similarities in appearance, organic structure and behaviour, methods based on genetic analysis have opened the road to cladistics. A given rank subsumes under it less general categories, that is, more specific descriptions of life forms. Above it, each rank is classified within more general categories of organisms and groups of organisms related to each other through inheritance of traits or features from common ancestors. The rank of any ''species'' and the description of its ''genus'' is ''basic''; which means that to identify a particular organism, it is usually not necessary to specify ranks other than these first two.

The Phylliroidae are a family of nudibranch sea snails, highly adapted to a pelagic lifestyle and occurring in tropical surface waters around the globe.

They swim by undulating their whole body. Their foot is very small, which helps to reduce drag. They are carnivores that prey on planktonic jelly fish Jellyfish and sea jellies are the informal common names given to the medusa-phase of certain gelatinous members of the subphylum Medusozoa, a major part of the phylum Cnidaria.
