Really a “secondary gill under the skin”? Unveiling “dorsal vessels” in freshwater slugs (Mollusca, Panpulmonata, Acochlidimorpha)

open access: yesJournal of Morphology, Volume 284, Issue 11, November 2023., 2023
In present study we investigate the circulatory and excretory systems of freshwater Acochlidium species from different Indo‐Pacific Islands in 3D‐microanatomical, histological and ultrastructural detail and shed light on the enigmatic, subepidermal “dorsal vessels.” Abstract The freshwater slugs of the genus Acochlidium (Heterobranchia, Gastropoda, and

Citizen scientists contributing to alien species detection: the case of fishes and mollusks in European marine waters

open access: yesEcosphere, Volume 13, Issue 1, January 2022., 2022
Abstract Citizen science (CS) expands the spatial and temporal scale of alien species records. As such, it has been recognized as a complementary tool in alien species management and large‐scale biodiversity conservation. The present study assessed the contribution of CS to the recording of marine alien fishes and mollusks in European marine waters by ...

Chemical defenses in Sacoglossan Opisthobranchs: Taxonomic trends and evolutionary implications

open access: yesScientia 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
