Molecular and morphological systematics of Elysia Risso, 1818 (Heterobranchia: Sacoglossa) from the Caribbean region

Zootaxa, 2016
The Caribbean is a biodiversity hotspot for photosynthetic sea slugs, with about 27 described species in the genus Elysia Risso, 1818. However, many species are poorly known or have complex taxonomic histories, complicating assessments of regional biodiversity and impeding studies of plastid symbiosis, speciation, and larval biology.

Phylogenetic evidence for multiple independent origins of functional kleptoplasty in Sacoglossa (Heterobranchia, Gastropoda)

Organisms Diversity & Evolution, 2014
Sacoglossa is a rather small taxon of marine slugs with about 300 described species, yet it is quite fascinating scientists for decades. This is mainly because of the ability of certain species to incorporate photosynthetically active plastids of their algae prey, a phenomenon known as functional kleptoplasty.

Phylogenetic systematics and classification of the Sacoglossa (Mollusca, Gastropoda, Opisthobranchia)

Philosophical Transactions of the Royal Society of London. Series B: Biological Sciences, 1996
Character analysis is performed based on anatomical information on 95 species of Sacoglossa (Mollusca, Opisthobranchia). Functional and developmental information is included, where available. Phylogenetic analysis to generic level is performed. The shelled Oxynoacea is a monophyletic group containing three families, Volvatellidae, Juliidae and ...

“Chloroplast symbiosis” and the extent to which it occurs in Sacoglossa (Gastropoda: Mollusca)

Biological Journal of the Linnean Society, 1974
Criteria for defining “chloroplast symbiosis” are outlined. Investigations are described into the presence or absence of chloroplast symbiosis in Limapontia capitata,“pale” and “dark” forms of L. depressa, Alderia modesta and Elysia viridis. Apart from E. viridis, only “pale” forms of L. depressa showed signs of the phenomenon.

Phagocytosis of chloroplasts in Placida dendritica (Gastropoda: Sacoglossa)

Journal of Experimental Zoology, 1976
AbstractPhagocytosis of algal chloroplasts by digestive gland cells in the sacoglossan opisthobranch Placida dendritica is described. It is suggested that engulfment of chloroplasts is accomplished by veils of cytoplasm which are derived from elongating microvilli.

EASTERN MEDITERRANEAN OPISTHOBRANCHIA: ELYSIIDAE (SACOGLOSSA = ASCOGLOSSA)

Journal of Molluscan Studies, 1988
An account is given of the elysiid sacoglossans collected on diving expeditions to the eastern Mediterranean shores of Yugoslavia and Greece during the period 1978– 1986, supplemented by material collected around Naples and some preserved specimens from other Mediterranean localities.

Comparison of Alimentary Systems in Shelled and Non‐shelled Sacoglossa (Mollusca, Opisthobranchia)

Acta Zoologica, 1991
AbstractThe Sacoglossa (= Ascoglossa) comprise a ‘complete’ evolutionary series from species with a large shell into which the animal can withdraw completely, through species with a reduced shell covering only the visceral mass, to shell‐less (‘nudibranchiate’) forms some of which have lateral wing‐like extensions, parapodia, others bearing leaf‐like ...

On Candinia (Sacoglossa: Juliidae), a new fossil genus of bivalved gastropods

Journal of Paleontology, 1996
The record of the fossil representatives of the family Juliidae is updated. The new genus Candinia is proposed, in the subfamily Juliinae, for two fossil species somewhat intermediate between Julia and Berthelinia. The new species Candinia pliocaenica is recorded from the lower Pliocene shallow marine deposits near Siena (Tuscany, Italy).
