Pseudovermis is genus of minute sea slugs, specifically aolid nudibranchs, marine gastropod mollusks or micromollusks in the family Pseudovermidae. [2] [3]
These extremely small sea slugs are meiofauna; they live among sand grains. Pseudovermis means fake worm, because these slugs resemble minute worms.
Species within the genus Pseudovermis include:
Armina is a genus of sea slugs, specifically nudibranchs, marine gastropod mollusks in the family Arminidae.
Stiliger is a genus of small and minute sacoglossan or sap-sucking sea slugs. They are marine gastropod mollusks in the family Limapontiidae.
Elysia is a genus of sea slugs, marine gastropod molluscs in the family Plakobranchidae. These animals are colorful sea slugs, and they can superficially resemble nudibranchs, but are not very closely related to them. Instead they are sacoglossans, commonly known as sap-sucking slugs.
Doto is a genus of dendronotid sea slug, a nudibranch in the Family Dotidae. This genus feeds on hydroids, as reflected by its serrated radula.
Chelidonura is a genus of small, sometimes colorful, sea slugs. These are headshield slugs or cephalaspideans, marine opisthobranch gastropod mollusks in the family Aglajidae.
Acanthodoris is a genus of sea slugs, dorid nudibranchs, shell-less marine gastropod mollusks in the family Onchidorididae. The genus is believed to have originated in the Atlantic Ocean in the Cretaceous period and spread to the Pacific Ocean. The relationships of Acanthodoris to the other genera in the family Onchidorididae were evaluated by molecular phylogeny in 2015.
Acochlidiacea, common name acochlidians, are a taxonomic clade of very unusual sea snails and sea and freshwater slugs, aquatic gastropod mollusks within the large clade Heterobranchia. Acochlidia is a variant spelling.
Plakobranchoidea is a taxonomic superfamily of sea slugs, marine gastropod mollusks within the superorder Sacoglossa.
Microhedylidae are a taxonomic family of sea slugs, marine gastropod mollusks within the clade Acochlidiacea.
Corambe is a genus of sea slugs, dorid nudibranchs, marine gastropod molluscs in family Corambidae within the superfamily Onchidoridoidea.
Philiopsis is a genus of often colorful, medium-sized sea slugs, marine opisthobranch gastropod mollusks. These are not nudibranchs; instead they are headshield slugs, in the clade Cephalaspidea.
Ascobulla is a genus of sea snails, bubble snails, a marine gastropod sacoglossan mollusk in the family Volvatellidae.
Discodoris is a genus of sea slugs, dorid nudibranchs, shell-less marine gastropod molluscs in the family Discodorididae.
Thordisa is a genus of sea slugs, dorid nudibranchs, shell-less marine gastropod mollusks in the family Discodorididae.
Rhopalomenia is a genus of cavibelonian solenogasters, shell-less, worm-like, marine mollusks.
Sclerodoris is a genus of sea slugs, specifically dorid nudibranchs. They are marine gastropod molluscs in the family Discodorididae.
Felimida is a genus of sea slugs, dorid nudibranchs, shell-less marine gastropod mollusks in the family Chromodorididae.
Aglaja is a genus of sea slugs, marine opisthobranch gastropod mollusks in the family Aglajidae.
Doto fragilis is a species of sea slug, a Dendronotid nudibranch, a marine gastropod mollusc in the family Dotidae.
Catriona is a genus of sea slugs, aeolid nudibranchs, marine gastropod molluscs in the family Trinchesiidae. All species were transferred to Tenellia as a result of a DNA phylogeny study in 2016. It was reinstated in 2017 on the basis of DNA and morphological criteria.
