On the Plakobranchidae (Gastropoda, Sacoglossa) from soft sediment habitats of Koh Tao, Gulf of Thailand, with descriptions of two new species [PDF]

open access: yesZooKeys, 2020
Research in recent years have provided rapid advances in biogeographic and taxonomic documentation of sea slugs around the world. However, efforts are lacking in surveying most coastlines and habitats in South-East Asia.

Mating behaviour in the sea slug Elysia timida (Opisthobranchia, Sacoglossa): hypodermic injection, sperm transfer and balanced reciprocity [PDF]

open access: yesFrontiers in Zoology, 2007
Background In simultaneous hermaphrodites with copulation and internal fertilization it is often unclear whether reciprocal sperm exchange results from the unconditional willingness of both partners to donate and receive sperm, or whether it follows from

Phenotypic diversity of Thuridilla hopei (Verany, 1853) (Gastropoda Heterobranchia Sacoglossa). A DNA-barcoding approach [PDF]

open access: yes, 2014
The sacoglossan Thuridilla hopei (Verany, 1853) shows highly diverse chromatic patterns. Based on the morphological examination of specimens from different Mediterranean localities, we have observed that in spite of this great variability in colours of T.

New records of marine “sea slugs” (Mollusca: Gastropoda: Heterobranchia) in the outlets of the estuary systems in Paraná, southern Brazil [PDF]

open access: yesCheck List, 2015
Four species of shell-less marine gastropods, col­lectively called “sea slugs”, are newly recorded from outlets of estuarine systems, the Paranaguá estuarine complex and Guaratuba Bay, on the coast of Paraná state.

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

open access: yesPeerJ, 2016
The coast of northern Primorye region, north of Peter the Great Bay has been sparsely studied in regards to its molluscan fauna, with just a few works reviewing the distribution of local mollusks.
