The exact systematics of nudibranchs are a topic of recent revision. Traditionally, nudibranchs have been treated as the order Nudibranchia, located in the gastropod mollusc subclass Opisthobranchia (the marine slugs: which consisted of nudibranchs, sidegill slugs, bubble snails, algae sap-sucking sea slugs, and sea hares).

Most creatures known as sea slugs are gastropods, i.e. they are sea snails (marine gastropod mollusks) that, over evolutionary time, have either entirely lost their shells or have seemingly lost their shells due to having a significantly reduced or internal shell. [1] The name "sea slug" is often applied to nudibranchs and a paraphyletic set of ...
A digestive tubule cell of the sea slug Elysia clarki, packed with chloroplasts taken from green algae. C = chloroplast, N = cell nucleus. Electron micrograph: scale bar is 3 μm. Kleptoplasty or kleptoplastidy is a process in symbiotic relationships whereby plastids, notably chloroplasts from algae, are sequestered by the host.
Melibe is a genus of sea slugs, nudibranchs, marine gastropod mollusks in the family Tethydidae. [2]Most nudibranchs are carnivores, but their prey is usually sessile or slow-moving animals such as sponges or bryozoans.
Flabellina is a genus of sea slugs, specifically aeolid nudibranchs. These animals are marine gastropod molluscs in the family Flabellinidae. [3] Taxonomic history
Janolus fuscus, head end towards the top. The bodies of nudibranchs in this species are semi-translucent and whitish-grey, and reach lengths of about 35mm. The body is covered in short cerata with brown cores, and the exterior fades to orange and then white at the tip.
A cnidosac is an anatomical feature that is found in the group of sea slugs known as aeolid nudibranchs, a clade of marine opisthobranch gastropod molluscs. [1] A cnidosac contains cnidocytes, stinging cells that are also known as cnidoblasts or nematocysts. These stinging cells are not made by the nudibranch, but by the species that it feeds upon.
Dirona is a genus of sea slugs, Pacific Ocean nudibranchs, marine, opisthobranch gastropod mollusks in the family Dironidae. [1] Dirona is the type genus of the family Dironidae. This genus is characterized by large, broad cerata.
