Body size and mating strategies in the simultaneous hermaphroditeOxynoe olivacea(Mollusca, Opisthobranchia, Sacoglossa) [PDF]

open access: yesFunctional Ecology, 2004
SummaryTo better understand the role and importance of body size in hermaphroditic mating system theory, the mating behaviour of the shelled sacoglossanOxynoe olivaceawas studied. This simultaneous hermaphrodite exhibits bilateral and unilateral sperm transfer and thus it is particularly suitable for studies on hermaphrodite sexual conflict.In this ...

Natural history clues to the evolution of bivalved gastropods (Mollusca: Gastropoda: Sacoglossa: Juliidae) [PDF]

open access: yesMarine Biodiversity, 2019
Bivalved gastropods (family Juliidae) are a pan-tropical group of small, green, extraordinary gastropods with a symmetrical clam-like shell. Only a single species of Juliidae has been reported in Malaysia, Berthelinia singaporensis Jensen, 2015, feeding on multiple species of siphonous green algae in the genus Caulerpa.

Sacoglossa or Acochlidia? 3D reconstruction, molecular phylogeny and evolution of Aitengidae (Gastropoda: Heterobranchia) [PDF]

open access: yesJournal of Molluscan Studies, 2011
The amphibious ‘bug-eating slug’ Aiteng ater Swennen & Buatip, 2009 shows a worm-like, compact body shape lacking any cephalic tentacles or body processes. Anatomically it has been described as showing an unusual mix of sacoglossan and acochlidian characters, thus the systematic affinities are uncertain.

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

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

open access: yesCheck List
The Mediterranean Sea is considered a hotspot of molluscan diversity even if many marine environments are still poorly explored and could mask rare and/or neglected diversity.
