he man sure had a palate covered o'er / With brass or steel, that on the rocky shore / First broke the oozy oyster's pearly coat / And risk'd the living morsel down his throat, " wrote John Gay (1685–1732), one of many poets since antiquity who became fascinated with the subject. More recently, Irish bard Seamus Heaney after enjoying fresh oysters with some friends, was so moved that he wrote a...

North American members in the genus Radiolucina are reviewed. A lectotype for the type species, Radiolucina amianta, is designated and descriptions and illustrations are provided. A description of a new species, Radiolucina jessicae, from the west coast of Mexico is presented. Key diagnostic species characteristics are outlined and compared among members of the genus.

The chemosymbiotic bivalves collected from the mud volcanoes of the Gulf of Cadiz are reviewed. Of the thirteen species closely associated with chemosynthetic settings two Solemyidae, Solemya (Petrasma) elarraichensissp. n. and Acharax gadiraesp. n., one Lucinidae, Lucinoma asapheussp. n., and one Vesicomyidae, Isorropodon megadesmussp. n. are described and compared to close relatives of their ...

In this paper, we employ the novel application of a reaction-diffusion model on a growing domain to examine growth patterns of the ligaments of arcoid bivalves (marine molluscs) using realistic growth functions. Solving the equations via a novel use of the finite element method on a moving mesh, we show how a reaction-diffusion model can mimic a number of different ligament growth patterns with...

A new anti-fouling drug, medetomidine, was tested to determine if it reduced the burying speed of a freshwater alien-invasive bivalve species, Corbicula fluminea. Corbicula are known to damage underwater structures and must be managed with chemical paints. The burying speeds of Corbicula were measured both before and after exposure to two different concentrations of medetomidine. The burying sp...

Blood cells are key component of organism for their survival and has profound role in defence mechanism of invertebrates similarly in bivalve species, the key role is healing wound and nutrients transportation. The Anadara antiquata is unique because of haemoglobin in their haemolymph and it is commonly found in Pakistani coast.  Present investigation revealed three types of Blood cells, namel...

Macrobenthic intertidal assemblages from five Atlantic Iberian estuaries were analyzed to develop an estuarine index. An R-mode analysis revealed a close association between the isopod Cyathura carinata, the polychaete Hediste diversicolor and the bivalve Scrobicularia plana. Although these species are abundant in all the estuaries considered, they tend to be absent from sites at the marine and...

Reported here are the genome sequences of three Vibrio coralliilyticus isolates RE87, AIC-7, and 080116A. Each strain was isolated in association with oyster larvae in commercial aquaculture systems. These draft genomes will be useful for further studies in understanding the genomic features contributing to V. coralliilyticus pathogenicity.

Circadial spawning times of medusa of the bivalve-inhabiting hydrozoans Eugymnanthea japonica Kubota and Eutima japonica Uchida are confirmed to be morning (possibly sunrise) for the former species and night for the latter. Eugymnanthea, with small, short-lived, univoltine medusae, seems to have evolved from a form similar to Eutima japonica, with larger, longer-lived, multivoltine medusae; the...
