Okadaiidae is a family of sea slugs, dorid nudibranchs, marine gastropod mollusks in the superfamily Polyceroidea. This family is within the clade Euctenidiacea. [1]
This family has no subfamilies.
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.
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 actually gastropods, i.e. they are sea snails 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.
Opisthobranchs is now an informal name for a large and diverse group of specialized complex gastropods which used to be united in the subclass Opisthobranchia. That taxon is no longer considered to represent a monophyletic grouping.
Dotidae are a taxonomic family of small sea slugs, nudibranchs, shell-less marine gastropod molluscs formerly assigned to the order Opisthobranchia, but now considered to belong to the clade Dexiarchia. This family is unassigned to a superfamily.
Vayssierea cinnabarea is a species of minute sea slug, a dorid nudibranch in the gastropod family Okadaiidae.
Chelidonura is a genus of small, sometimes colorful, sea slugs. These are headshield slugs or cephalaspideans, marine opisthobranch gastropod mollusks in the family Aglajidae.
Chelidonura amoena is a species of sea slug, or "headshield slug", a marine opisthobranch gastropod mollusk in the family Aglajidae.
Juliidae, common name the bivalved gastropods, is a family of minute sea snails, marine gastropod mollusks or micromollusks in the superfamily Oxynooidea, an opisthobranch group. These are sacoglossan (sap-sucking) sea snails, and many of them are green in color.
Nudipleura are a clade of sea snails and sea slugs, marine gastropod mollusks within the large clade Heterobranchia.
The Ptenoglossa is an informal taxonomic group of sea snails. This group was considered paraphyletic or polyphyletic by Ponder and Lindberg (1997) in their classification of gastropod molluscs.
Pinufiidae is a family of sea slugs, specifically nudibranchs, marine gastropod molluscs, in the clade Nudipleura. There are no subfamilies in the Pinufiidae.
Dironidae is a family of nudibranchs, marine gastropod molluscs, in the clade Euthyneura. There are no subfamilies in Dironidae.
Heroidae is a family of sea slugs, nudibranchs, marine gastropod molluscs in the clade Nudipleura. There are no subfamilies in Heroidae.
Acochlidiidae are a taxonomic family of shell-less freshwater gastropods, aquatic gastropod mollusks within the clade Acochlidiacea.
Tritonia bollandi is a species of dendronotid nudibranch. It is a marine gastropod mollusc in the family Tritoniidae.
Vayssierea is a genus of sea slugs, dorid nudibranchs, shell-less marine gastropod mollusks in the family Okadaiidae.
Vayssierea felis is a species of sea slug, a dorid nudibranch, a marine gastropod mollusk in the family Okadaiidae.
Okenia felis is a species of very small sea slug, specifically a dorid nudibranch, a marine gastropod mollusc in the family Goniodorididae. This species was first discovered in 2008 at Point Lobos State Reserve, in Monterey County, California, by local divers. It was named and described in 2010.
Elysia diomedea is a species of sea slug, a marine gastropod mollusc in the family Plakobranchidae.
Goniodoris felis is a species of sea slug, a dorid nudibranch, a marine gastropod mollusc in the family Goniodorididae.
