Chloroplast incorporation and long-term photosynthetic performance through the life cycle in laboratory cultures of Elysia timida (Sacoglossa, Heterobranchia) [PDF]
Frontiers in Zoology, 2014 The Mediterranean sacoglossan Elysia timida is one of the few sea slug species with the ability to sequester chloroplasts from its food algae and to subsequently store them in a functional state in the digestive gland cells for more than a month, during which time the plastids retain high photosynthetic activity (= long-term retention). Adult E. timida

Transcriptomic Evidence That Longevity of Acquired Plastids in the Photosynthetic Slugs Elysia timida and Plakobranchus ocellatus Does Not Entail Lateral Transfer of Algal Nuclear Genes [PDF]
Molecular Biology and Evolution, 2011 Sacoglossan sea slugs are unique in the animal kingdom in that they sequester and maintain active plastids that they acquire from the siphonaceous algae upon which they feed, making the animals photosynthetic. Although most sacoglossan species digest their freshly ingested plastids within hours, four species from the family Plakobranchidae retain their

Light modulates the lipidome of the photosynthetic sea slug Elysia timida
Biochimica et Biophysica Acta (BBA) - Molecular and Cell Biology of Lipids, 2023 Long-term kleptoplasty, the capability to retain functional stolen chloroplasts (kleptoplasts) for several weeks to months, has been shown in a handful of Sacoglossa sea slugs. One of these sea slugs is Elysia timida, endemic to the Mediterranean, which retains functional chloroplasts of the macroalga Acetabularia acetabulum.

Crustaceans and Marine Heterobranchia: A New Symbiotic Relationship in the Mediterranean Sea
Diversity, 2021 The “solar-powered” Elysia timida (Risso, 1818) is an endemic Mediterranean sacoglossan living in rocky substrates at shallow water. During a scuba dive, one E. timida was photographed and collected.

The photon menace: kleptoplast protection in the photosynthetic sea slugElysia timida [PDF]
Journal of Experimental Biology, 2019 Absorption of excessive light by photosymbiotic organisms leads to the production of reactive oxygen species that can damage both symbiont and host. This is highly relevant in sacoglossan sea slugs that host functional chloroplasts “stolen” from their algal foods (kleptoplasts), due to limited repair capacities resulting from the absence of algal ...

Photoprotective Non-photochemical Quenching Does Not Prevent Kleptoplasts From Net Photoinactivation
Frontiers in Ecology and Evolution, 2018 The enigmatic association of photosynthetically active chloroplasts from algae and some sacoglossan sea slugs, called functional kleptoplasty, is a functional unique system of photosymbioses observed in metazoans.

Chemical defenses in Sacoglossan Opisthobranchs: Taxonomic trends and evolutionary implications
Scientia Marina, 2004 Sacoglossan sea slugs (Mollusca: Opisthobranchia) are one of the few groups of specialist herbivores in the marine environment. Sacoglossans feed suctorially on the cell sap of macroalgae, from which they "steal" chloroplasts (kleptoplasty) and deterrent

Preservation and remodelling of chloroplast lipids in photosynthetic sea slug host cells
Frontiers in Marine ScienceThe capacity to retain long-term functional algal chloroplasts within animal cells is a singular trait of certain Sacoglossa sea slugs. The sequestered chloroplasts (kleptoplasts) confer photosynthetic capacity to the host.

Physiologia Plantarum, Volume 176, Issue 2, March/April 2024.Abstract Sacoglossa sea slugs have garnered attention due to their ability to retain intracellular functional chloroplasts from algae, while degrading other algal cell components. While protective mechanisms that limit oxidative damage under excessive light are well documented in plants and algae, the photoprotective strategies employed by these ...
