Two very elegant species of Sea-slug, viz., Eolis punctata [i.e. Facelina annulicornis], and Tritonia arborescens [i.e. Dendronotus frondosus], certainly produce audible sounds. Professor Grant, who first observed the interesting fact in some specimens of the latter, which he was keeping in an aquarium, says of the sounds that 'they resemble ...

[2] Costasiella ocellifera, and other members of the family Costasiellidae are often mistakenly classified as nudibranchs because they superficially resemble other species of that group, but they are actually a part of the Sacoglossa superorder of sea slugs ...
Gastropteridae is a fairly diverse family containing four genera and thirty-three described species. Adults have an internal reduced shell or no shell at all. The body is fairly short, usually under 10 mm (0.4 in) in length, but exceptionally up to 35 mm (1.4 in). [3]
Onchidiidae are a family of small, air-breathing sea (and land) slugs. They are shell-less marine (except for two species) [2] pulmonate gastropod molluscs. Onchidiidae is the only family within the superfamily Onchidioidea. These animals are quite unusual in that they are emphatically not opisthobranchs with gills, as are almost all of the sea ...
The order Cephalaspidea, also known as the headshield slugs and bubble snails, is a major taxon of sea slugs and bubble snails, marine gastropod mollusks within the larger clade Euopisthobranchia. [1] Bubble shells is another common name for these families of marine gastropods, some of which have thin bubble-like shells. [2]
