Doridoxa Walteri
Doridoxidae, commonly known as doridoxid nudibranchs, are a small, enigmatic Taxonomy (biology), taxonomic family of shell-less sea slugs, Marine (ocean), marine gastropod molluscs in the clade Cladobranchia within the clade Nudibranchia. Doridoxidae is currently the only family in the superfamily Doridoxoidea, within the clade Pseudoeuctenidiacea (= Doridoxida). Molecular evidence shows that it groups with the genera ''Doridomorpha'' and ''Heterodoris'' and the family ''Arminidae'' and close to ''Tritoniidae''.Korshunova, T.; Martynov, A.

Sea Slug
Sea slug is a common name for some marine invertebrates with varying levels of resemblance to terrestrial slugs. Most creatures known as sea slugs are gastropods, i.e. they are sea snails (marine gastropod mollusks) that over evolutionary time have either completely lost their shells, or have seemingly lost their shells due to having a greatly reduced or internal shell. The name "sea slug" is most often applied to nudibranchs, as well as to a paraphyletic set of other marine gastropods without obvious shells. Sea slugs have an enormous variation in body shape, color, and size. Most are partially translucent. The often bright colors of reef-dwelling species implies that these animals are under constant threat of predators, but the color can serve as a warning to other animals of the sea slug's toxic stinging cells (nematocysts) or offensive taste. Like all gastropods, they have small, razor-sharp teeth, called radulas. Most sea slugs have a pair of rhinophores—sensory te ...

Tritoniidae
Tritoniidae is a taxonomic family of nudibranchs in the suborder Cladobranchia, shell-less marine gastropod molluscs.MolluscaBase (2018)Tritoniidae Lamarck, 1809.Accessed on 2021-01-01 This family includes some of the largest known nudibranchs, with the NE Atlantic species ''Tritonia hombergii'' reaching 20 cm in length. It is the only family in the monotypic superfamily Tritonioidea. Distribution These nudibranchs occur worldwide in warm and temperate seas and in the coldest waters and deep sea, wherever the octocorals which they eat are found. Ecology Members of the family Tritoniidae feed on octocorals, including sea pens, alcyonarian soft corals, and gorgonians, often being cryptic in shape and colouration upon them.García-Matucheski, S. and Muniain, C.

Arminidae
Arminidae is a family of sea slugs, marine gastropod mollusks in the superfamily Arminoidea. Taxonomy The family Arminidae is classified within the clade Cladobranchia, itself belonging to the clade Nudibranchia (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005). This family has been renamed several times. It was originally named by d'Orbigny in 1841 as Diphyllidiidae, by H. Adams and A. Adams as Pleurophyllidiidae in 1854, by Bergh as Pleuroleuridae in 1874, by Verrill and Emerton as Heterodorididae in 1882, by P. Fischer as Dermatobranchidae in 1883 and as Atthilidae by Bergh in 1899. The name Arminidae is now in prevailing usage. Genera The type genus is '' Armina'' Rafinesque, 1814 Genera in the family Arminidae include: * '' Armina'' Rafinesque, 1814 *''Dermatobranchus'' van Hasselt, 1824 *'' Histiomena'' Mörch, 1860 * ''Heterodoris'' Verrill & Emerton, 1882 .

Doridomorpha
''Doridomorpha'' is a genus of sea slugs, arminoid nudibranchs, marine gastropod mollusks in the family Doridomorphidae. Taxonomy The phylogenetic position of ''Doridomorpha'' was clarified in 2020 as a result of an integrative taxonomic study of the family Tritoniidae.Korshunova, T.; Martynov, A.

Mollusc
Mollusca is the second-largest phylum of invertebrate animals after the Arthropoda, the members of which are known as molluscs or mollusks (). Around 85,000 extant species of molluscs are recognized. The number of fossil species is estimated between 60,000 and 100,000 additional species. The proportion of undescribed species is very high. Many taxa remain poorly studied. Molluscs are the largest marine phylum, comprising about 23% of all the named marine organisms. Numerous molluscs also live in freshwater and terrestrial habitats. They are highly diverse, not just in size and anatomical structure, but also in behaviour and habitat. The phylum is typically divided into 7 or 8 taxonomic classes, of which two are entirely extinct. Cephalopod molluscs, such as squid, cuttlefish, and octopuses, are among the most neurologically advanced of all invertebrates—and either the giant squid or the colossal squid is the largest known invertebrate species.

Gastropod
The gastropods (), commonly known as snails and slugs, belong to a large taxonomic class of invertebrates within the phylum Mollusca called Gastropoda (). This class comprises snails and slugs from saltwater, from freshwater, and from land. There are many thousands of species of sea snails and slugs, as well as freshwater snails, freshwater limpets, and land snails and slugs. The class Gastropoda contains a vast total of named species, second only to the insects in overall number. The fossil history of this class goes back to the Late Cambrian. , 721 families of gastropods are known, of which 245 are extinct and appear only in the fossil record, while 476 are currently extant with or without a fossil record. Gastropoda (previously known as univalves and sometimes spelled "Gasteropoda") are a major part of the phylum Mollusca, and are the most highly diversified class in the phylum, with 65,000 to 80,000 living snail and slug species.

Marine (ocean)
The ocean (also the sea or the world ocean) is the body of salt water that covers approximately 70.8% of the surface of Earth and contains 97% of Earth's water. An ocean can also refer to any of the large bodies of water into which the world ocean is conventionally divided."Ocean." ''Merriam-Webster.com Dictionary'', Merriam-Webster, |
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 evolu ...
