On the origin of Acochlidia and other enigmatic euthyneuran gastropods, with implications for the systematics of Heterobranchia [PDF]

open access: yes, 2010
Background A robust phylogenetic hypothesis of euthyneuran gastropods, as a basis to reconstructing their evolutionary history, is still hindered by several groups of aberrant, more or less worm-like slugs with unclear phylogenetic relationships.

Mucopolysaccharides secreted by the sea slug Elysia crispata incorporate carbon via kleptoplast photosynthesis

open access: yesFrontiers in Marine Science
Some Sacoglossa sea slugs feed on macroalgae and sequester chloroplasts in the cells of their digestive diverticulum. In some species, mostly within the genus Elysia, the stolen chloroplasts – kleptoplasts – remain photosynthetically competent for weeks ...

Observations during embryonic development in the genus Doto (Gastropoda, Opisthobranchia) [PDF]

open access: yes, 2017
While working on taxonomic problems in the family Dotoidae and comparing the Mediterranean and Atlantic species (Schmekel & Kress, in the Press), it became apparent that very little embryological information was available for this group, other than that ...

A molecular phylogeny of Thuridilla Bergh, 1872 sea slugs (Gastropoda, Sacoglossa) reveals a case of flamboyant and cryptic radiation in the marine realm [PDF]

open access: yes, 2021
The genus Thuridilla Bergh, 1872 comprises mostly tropical sap-sucking sea slugs species with flamboyantly coloured forms. However, the potential for cryptic or pseudocryptic species masked by convergent or polymorphic colour patterns has not been tested
