Alderia is a genus of sea slugs, marine gastropod mollusks in the family Limapontiidae. These are sacoglossan sea slugs.
The name Alderia first appeared in Thompson's 1844 Report on the fauna of Ireland [2] as a nomen nudum (Allmann MSS).
Species within the genus Alderia include:
Rostanga is a genus of sea slugs in the family Discodorididae. Some sources, such as The Sea Slug Forum still classify Rostanga in the family Dorididae.
William Thompson was an Irish naturalist celebrated for his founding studies of the natural history of Ireland, especially in ornithology and marine biology. Thompson published numerous notes on the distribution, breeding, eggs, habitat, song, plumage, behaviour, nesting and food of birds. These formed the basis of his four-volume The Natural History of Ireland, and were much used by contemporary and later authors such as Francis Orpen Morris.
In biology, a taxon with a disjunct distribution is one that has two or more groups that are related but considerably separated from each other geographically. The causes are varied and might demonstrate either the expansion or contraction of a species' range.
Limapontiidae is a taxonomic family of small to minute sacoglossan sea slugs. These are marine opisthobranch gastropod mollusks.
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.
The Pleurobranchidae are a taxonomic family of sea slugs, marine gastropod molluscs in the clade Pleurobranchomorpha.
Pleurobranchus is a genus of sea slugs, specifically side-gill slugs, marine gastropod mollusc in the family Pleurobranchidae.
Alderia willowi is a species of sea slug, a marine gastropod mollusc in the family Limapontiidae. It is a sacoglossan.
Akera bullata, named the royal flush sea slug, is a species of sea snail, a marine opisthobranch gastropod mollusk in the family Akeridae, a family that is related to the sea hares. This species is the only European representative of the genus Akera.
Hypselodoris regina is a conspicuous species of sea slug or dorid nudibranch, a marine gastropod mollusk in the family Chromodorididae.
Berthellina is a genus of sea slugs, marine gastropod molluscs in the family Pleurobranchidae.
Berghia creutzbergi is a species of sea slug, an aeolid nudibranch. It is a shell-less marine gastropod mollusc in the family Aeolidiidae.
Aporodoris is a genus of sea slugs, dorid nudibranch, shell-less marine gastropod molluscs in the family Discorididae.
Microchlamylla gracilis, sometimes known by the common name slender eolis, is a species of sea slug, an aeolid nudibranch, a marine gastropod mollusc in the family Flabellinidae.
Antiopella cristata, sometimes known by the common name crested aeolis, is a species of nudibranch, a marine gastropod mollusc in the family Janolidae.
Goniodoris nodosa is a species of sea slug, a dorid nudibranch, a marine gastropod mollusc in the family Goniodorididae.
Trinchesia genovae is a species of sea slug, an aeolid nudibranch, a marine gastropod mollusc in the family Trinchesiidae.
Amphorina farrani is a species of sea slug or nudibranch, a marine gastropod mollusc in the family Eubranchidae. Several species of Eubranchus were transferred to Amphorina in 2020.
Alderia modesta is a species of sea slug, a marine gastropod mollusc in the family Limapontiidae. It is found in estuarine habitats and saltmarshes on either side of the North Atlantic and the North Pacific Oceans.
