The Pleurobranchidae are a taxonomic family of sea slugs, marine gastropod molluscs in the clade Pleurobranchomorpha.
Species in the family Pleurobranchidae have a prominent mantle and an internal shell that becomes reduced or is lost completely in adults. [3] Some adult species have been seen feeding on ascidians. Larval pleurobranchids can be planktotrophic (feeding on plankton), lecithotrophic (deriving nutrition from yolk), or direct developing.
Like all Pleurobranchomorpha, they breathe through an external gill, located on the right side (contrary to nudibranchs who have it on the back), just after the genital organ.
Many species produce secretions from their rich glandular mantle as a chemical defense against predators. [4] Even the production of sulfuric acid has been reported. [5]
Until 2005, this family was placed in the suborder Notaspidea. However, in the taxonomy of Bouchet & Rocroi (2005), the family Pleurobranchidae was placed in the superfamily Pleurobranchoidea, the only family belonging to the subclade Pleurobranchomorpha (sister to the subclade Nudibranchia), part of the clade Nudipleura.
Armina is a genus of sea slugs, specifically nudibranchs, marine gastropod mollusks in the family Arminidae.
Janolus is a genus of small to large sea slugs, or more accurately nudibranchs, marine gastropod mollusks, in the family Janolidae. The name Janolus is derived from the two-headed god Janus, in ancient Roman mythology.
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.
Lamellaria is a genus of small slug-like sea snails, marine gastropod molluscs in the family Velutinidae.
Acanthodoris is a genus of sea slugs, dorid nudibranchs, shell-less marine gastropod mollusks in the family Onchidorididae. The genus is believed to have originated in the Atlantic Ocean in the Cretaceous period and spread to the Pacific Ocean. The relationships of Acanthodoris to the other genera in the family Onchidorididae were evaluated by molecular phylogeny in 2015.
Polycera is a genus of sea slugs, specifically nudibranchs, shell-less marine gastropod molluscs in the family Polyceridae.
Flabellina is a genus of sea slugs, specifically aeolid nudibranchs. These animals are marine gastropod molluscs in the family Flabellinidae.
Pleurobranchus is a genus of sea slugs, specifically side-gill slugs, marine gastropod mollusc in the family Pleurobranchidae.
Doris is a genus of sea slugs, specifically dorid nudibranchs. These animals are marine gastropod molluscs in the family Dorididae.
Corambe is a genus of sea slugs, dorid nudibranchs, marine gastropod molluscs in family Corambidae within the superfamily Onchidoridoidea.
Phyllidia is a genus of sea slugs, dorid nudibranchs, shell-less marine gastropod molluscs in the family Phyllidiidae.
Marionia is a genus of sea slugs, specifically dendronotid nudibranchs, marine gastropod molluscs in the family Tritoniidae.
Tenellia is a genus of sea slugs, aeolid nudibranchs, marine gastropod mollusks in the family Trinchesiidae.
Berthella is a genus of sea slugs, marine gastropod mollusks in the family Pleurobranchidae.
Berthellina is a genus of sea slugs, marine gastropod molluscs in the family Pleurobranchidae.
Spurilla is a genus of sea slugs, aeolid nudibranchs, marine gastropod mollusks in the family Aeolidiidae.
Felimida is a genus of sea slugs, dorid nudibranchs, shell-less marine gastropod mollusks in the family Chromodorididae.
Felimare is a genus of sea slugs, dorid nudibranchs, shell-less marine gastropod molluscs in the subfamily Miamirinae of the family Chromodorididae.
Pleurobranchus crossei is a species of pleurobranchid sea slug, a type of marine gastropod mollusc
