Pseudovermis hancocki Challis, 1969 | |
Pseudovermis hancocki is species of minute sea slug, specifically an aeolid nudibranch, a marine gastropod mollusc or micromollusk in the family Pseudovermidae.
These extremely small sea slugs are meiofauna; they live among sand grains.
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.
Glaucus atlanticus is a species of small, blue sea slug, a pelagic aeolid nudibranch, a shell-less gastropod mollusk in the family Glaucidae.
Aglajidae is a family of often colorful, medium-sized, sea slugs, marine opisthobranch gastropod mollusks. These are not nudibranchs; instead they are headshield slugs, in the clade Cephalaspidea.
Placida dendritica is a species of minute sea slug, a marine opisthobranch gastropod mollusk or micromollusk in the family Limapontiidae.
Notaspidea, also known as the sidegill slugs, is an artificial grouping of sea slugs which is now split into two unrelated groups, the Umbraculida and the Pleurobranchomorpha.
The umbrella slug is a species of large sea snail or limpet, a marine gastropod mollusc in the family Umbraculidae. It is found in tropical to warm temperate parts of the Indo-Pacific and Atlantic Oceans, where it feeds on sponges.
Spurilla faustina is a rare species of sea slug, an aeolid nudibranch, a marine gastropod mollusk in the family Aeolidiidae.
Pseudovermidae is a taxonomic family of minute sea slugs, specifically aolid nudibranchs, marine gastropod mollusk or micromollusks.
Phylliroe bucephalum is a species of pelagic parasitic nudibranch, a marine gastropod mollusc in the family Phylliroidae.
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.
Chelidonura is a genus of small, sometimes colorful, sea slugs. These are headshield slugs or cephalaspideans, marine opisthobranch gastropod mollusks in the family Aglajidae.
Pleurobranchaea maculata, or the grey side-gilled slug, is a species of sea slug, specifically a side-gill slug or notaspidean. It is a marine gastropod mollusc in the family Pleurobranchaeidae.
Jason mirabilis is a species of sea slug, or more precisely an aeolid nudibranch, a marine gastropod mollusc in the family Facelinidae.
Ceratosoma amoenum, or the clown nudibranch, is a species of colorful dorid nudibranch, a sea slug, a shell-less marine gastropod mollusk in the family Chromodorididae.
Elysia maoria is a small to medium-sized species of sea slug, a marine gastropod mollusk in the family Plakobranchidae. This sea slug resembles a nudibranch, but it is not closely related to that order of gastropods, instead it is a sacoglossan. It occurs in New Zealand and Australia.
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.
William B. Rudman, usually known as Bill Rudman, is a malacologist from New Zealand and Australia. In particular he studies sea slugs, opisthobranch gastropod molluscs, and has named many species of nudibranchs.
Hypselodoris kaname is a species of sea slug or dorid nudibranch, a marine gastropod mollusk in the family Chromodorididae.
Coryphellina albomarginata is a species of sea slug, an aeolid nudibranch, a marine gastropod mollusc in the family Flabellinidae.
