Microbiome characterization of the sea slugs Elysia viridis and Placida dendritica: insights into potential roles in kleptoplasty [PDF]

BMC Microbiology
Background Kleptoplasty is the process by which functional chloroplasts from algae food sources are sequestered and retained by a host organism. Some sacoglossan sea slugs display this ability, enabling them to survive extended periods of food shortage ...

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

Frontiers 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 on the Benthic Heterobranch “Sea Slugs” (Mollusca: Gastropoda) of Lampedusa, the Southernmost Island of Italy (MPA Isole Pelagie)

Journal of Marine Science and Engineering
Thanks to their striking shapes and colors, heterobranch “sea slugs” are probably the most sought-after group of marine critters by scuba divers around the world.

Ecological speciation by sympatric host shifts in a clade of herbivorous sea slugs, with introgression and localized mitochondrial capture between species

Molecular Phylogenetics and Evolution, 2022
Host shifting in insect-plant systems was historically important to the development of ecological speciation theory, yet surprisingly few studies have examined whether host shifting drives diversification of marine herbivores. When small-bodied consumers

Evolution and theft: loss of state transitions in Bryopsidales macroalgae and photosynthetic sea slugs

bioRxiv
Green macroalgae within the order Bryopsidales lack the fundamental photoprotective mechanisms of green algae, the xanthophyll cycle and energy-dependent dissipation of excess light. Here, by measuring chlorophyll fluorescence at 77K after specific light

Heterobranch Sea Slugs s.l. (Mollusca, Gastropoda) from the Southern Ocean: Biodiversity and Taxonomy

Diversity
The Southern Ocean, located between Antarctica and the southern tips of South America, Africa and Australia, encompasses an immense area across the southern Atlantic, Pacific and Indian oceans with no clearly defined limits.

Photoprotective mechanisms inElysiaspecies hostingAcetabulariachloroplasts shed light on host-donor compatibility in photosynthetic sea slugs

bioRxiv
Sacoglossa sea slugs have garnered attention due to their ability to retain intracellular functional chloroplasts from algae, while degrading other algal cell components.

Transcriptomics provides a robust framework for the relationships of the major clades of cladobranch sea slugs (Mollusca, Gastropoda, Heterobranchia), but fails to resolve the position of the enigmatic genus Embletonia [PDF]

bioRxiv, 2020
Background The soft-bodied cladobranch sea slugs represent roughly half of the biodiversity of marine nudibranch molluscs on the planet. Despite their global distribution from shallow waters to the deep sea, from tropical into polar seas, and their ...

Beyond Capricornia: Tropical Sea Slugs (Gastropoda, Heterobranchia) Extend Their Distributions into the Tasman Sea

Diversity, 2018
There is increasing evidence of poleward migration of a broad range of taxa under the influence of a warming ocean. However, patchy research effort, the lack of pre-existing baseline data, and taxonomic uncertainty for some taxa means that unambiguous ...

Laboratory Rearing of the Photosynthetic Sea Slug Elysia crispata (Gastropoda, Sacoglossa): Implications for the Study of Kleptoplasty and Species Conservation [PDF]

Biology
Some Sacoglossa sea slugs are capable of stealing and maintaining functional intracellular chloroplasts—kleptoplasts—from their macroalgal prey for periods of up to several months, a process known as kleptoplasty. Although the cultivation of these marine
