- L'expression « Limace de mer » est un nom vernaculaire ambigu en français, pouvant désigner plusieurs espèces de mollusques gastéropodes marins dépourvus de coquille et dont certains traits morphologiques évoquent vaguement les limaces terrestres. Il en existe plus de 3000 espèces reparties dans toutes les mers et océans de la Terre. Elles peuvent vivre jusqu'à 700 mètres de profondeur et mesurent pour la plupart moins de 5 centimètres, sauf quelques espèces comme la danseuse espagnole, qui peut atteindre 60 centimètres de long. Elles possèdent des rhinophores et sont hermaphrodites. Mais en l'absence de partenaire, elles peuvent se reproduire par parthénogenèse. (fr)
- 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 tentacles used primarily for the sense of smell—on their head, with a small eye at the base of each rhinophore. Many have feathery structures (cerata) on the back, often in a contrasting color, which act as gills. All species of genuine sea slugs have a selected prey animal on which they depend for food, including certain jellyfish, bryozoans, sea anemones, and plankton as well as other species of sea slugs. Sea slugs have brains. For example, Aplysia californica has a brain of about 20,000 nerve cells. (en)
- ウミウシ（海牛）とは後鰓類中で、貝殻が縮小、体内に埋没、消失などした種の総称。 後鰓類は、軟体動物門腹足綱（巻貝の仲間）に属し、以前は後鰓亜綱とされていた。近年は、希に後鰓目とすることがあるが、正式な分類群としては認めないことが多い。後鰓目を置く場合、以前の目は繰り下がって亜目となる。このような不統一があるため、以下では原則として、分類群は単に類とする。 (ja)
- Lesma-marinha, ou lesma-do-mar, é o nome comum dado a um conjunto alargado de invertebrados marinhos que apresentam uma morfologia externa que os torna semelhantes às lesmas terrestres. A maioria das espécies assim designadas são gastrópodes nudibrânquios, aparentados com os búzios, que durante o seu percurso evolucionário perderam as suas conchas ou as tiveram reduzidas a pequenas conchas internas. A designação não tem valor taxonómico pois agrupa pois é também aplicada a um largo conjunto parafilético de organismos que inclui outros gastrópodes marinhos desprovidos de concha externa e mesmo organismos pertencentes a outros filos (como alguns pepinos-do-mar do filo Echinodermata).
