Sympatric sibling species: the case of Caloria elegans and Facelina quatrefagesi (Gastropoda: Nudibranchia)

open access: yesScientia Marina, 2016
The aeolid nudibranch Caloria elegans (Facelinidae) is quite common in the Mediterranean Sea and eastern Atlantic Ocean and is easily recognized by the presence of a typical black spot at the apical portion of its cerata.

Material Before Morphology: Substrate‐Dependent Mechanical Tuning of Radular Teeth

open access: yesAdvanced Materials Interfaces, EarlyView.
Substrate‐dependent material tuning in Clausilia radular teeth. Closely related taxa retain a conserved gross tooth morphology, but differ in elemental composition and mechanical properties according to feeding substrate. Rock‐associated taxa show increased Ca–Si enrichment and higher stiffness and hardness, especially in the central radular region ...

A Pentaradial and Bilateral Combined Photoreception System in the Sea Cucumber is Mediated by a Blue Light‐Sensitive R‐Opsin

open access: yesAdvanced Science, EarlyView.
The sea cucumber Holothuria leucospilota detects blue and adjacent wavelengths of light via an r‐opsin with a maximum absorption at 459 nm. In the oral tentacles, papillae, and tube feet, distinct light‐sensing structures with specialized morphologies are formed, constituting a unique pentaradial and bilateral combined photoreception system.

Pannonian moluscs from site Osek-2 in Slovenske gorice, Slovenia

open access: yesGeologija, 2015
Remains of molluscs from a small outcrop at Zgornji Osek (section Osek-2) in Slovenske gorice are described. Some melanopsid gastropods and a bivalve Mytilopsis ornithopsis (Brusina, 1892) were documented.

Vyhodnotenie malakofauny z náplavov Neresnice (stredné Slovensko) [PDF]

open access: yesMalacologica Bohemoslovaca, 2011
Sampling of flood debris deposits can be useful method in insufficiently surveyed areas. This sampling method also allows us to detect the presence of rare and endangered species in the study area.

Two Routes to Land: Genomic Underpinnings of Parallel Aerial Egg Deposition in Aquatic Old‐World Pila and New‐World Pomacea (Ampullariidae)

open access: yesAdvanced Science, EarlyView.
Comparative genomics of Gondwana‐diverged Pila and Pomacea reveals parallel evolution of aerial oviposition. Convergent chromosomal rearrangements reshape regulatory landscapes within topologically associating domains. Lineage‐specific gene family expansions and viral‐derived perivitelline proteins (PV1) underpin desiccation resistance.

Malakofauna PR Hemže-Mýtkov [PDF]

open access: yesMalacologica Bohemoslovaca, 2009
Altogether, 78 mollusc species were recorded in the Hemže-Mýtkov Nature Reserve (East Bohemia, Czech Republic) during 2005–06. This locality harbours 32% of the total mollusc fauna of the Czech Republic at only 29 ha.

Characterization of the Myostracum Layers in Molluscs Reveals a Conservative Shell Structure

open access: yesFrontiers in Marine Science, 2022
Molluscs produce rigid shells to protect their soft bodies from predators and physiochemical violations. The soft tissues attach to shells via the myostracum layer (also called adductor muscle scar, AMS) which bears tremendous contract force and is of ...

T2T Genome Assembly and Multi‐Omics Data Reveal Terrestrial Adaptation and Mucus Biosynthesis in Tropical Leatherleaf Slug (Laevicaulis alte)

open access: yesAdvanced Science, EarlyView.
A gap‐free genome assembly and multi‐omics comparison of the terrestrial slug Laevichaulis alte with an aquatic relative reveal that expansion of the VEGF family orchestrates mucus production, lipid metabolism, and immune defense—highlighting key molecular innovations for conquering life on land.
