Biology and functional morphology of the pallial organs of the Antarctic bivalve Mysella charcoti (Lamy, 1906) (Galeommatoidea: Lasaeidae)
TLDR
The role of the foot and its ciliature during the processes of dislodgement and burrowing within the sediment are described and M. charcoti is the first known lasaeid with ctenidia formed of the descending lamellae of the inner demibranchs only.
A new species of Mysella Angas, 1877 (Bivalvia: Galeommatoidea) from Admiralty Bay, King George Island, South Shetlands, Antarctica, with data on its biology and functional anatomy
Mysella narchii sp. nov. is described from the material collected in shallow-waters of Admiralty Bay at King George Island, South Shetlands, Antarctica. The species is characterized by shell
Functional morphology of Cardiomya cleryana (d'Orbigny, 1842) (Bivalvia: Anomalodesmata: Cuspidariidae) from Brazilian waters: new insights into the lifestyle of carnivorous bivalves
TLDR
This study provides new insights into the morphology and behaviour of the Cuspidariidae and an anatomical comparison between Cardiomya and Bathyneaera has revealed close affinities.
A New Species of Cyamiocardium Soot-Ryen, 1951 from Shallow Waters off Brazil, with a Discussion on the Anatomical Characters of the Cyamiidae (Bivalvia: Cyamioidea)
TLDR
This finding of a cyamiid from Brazil represents the extension of the geographical distribution of this family further north in the southwestern Atlantic Ocean and reveals that some anatomical characters are variable in the genus Cyamiocardium.
Falcidens targatus and F. acutargatus: two species of Caudofoveata (Mollusca, Aplacophora) new for Brazil
TLDR
Two species of Falcidens Salvini-Plawen, 1968 (Chaetodermatidae) are recorded for the first time from Campos Basin, off south-eastern Brazil and the finding of F. (Ch.) acutargatus from off Rio de Janeiro suggests that this species has a continuous distribution in the slope through all the Western Atlantic.
New perspectives on the dispersal mechanisms of the Antarctic brooding bivalve Mysella charcoti (Lamy, 1906)
TLDR
The finding indicates that the snug-fitting shell of Mysella functions as a barrier to digestive enzymes, which allows MysellA to be passively dispersed and colonize new habitats or re-colonize shallow-water substrates severely impacted by ice scours.
Exotic species dominate marinas between the two most populated regions in the southwestern Atlantic Ocean.
TLDR
It is shown that communities associated with artificial substrata along this Brazilian urbanized area are dominated by exotic species and that using abundance data along with species identity can improve the understanding of the importance of exotic species for the dynamics of biological communities.
Bivalves of the São Sebastião Channel, north coast of the São Paulo state, Brazil
TLDR
This work provides a species list of bivalves inhabiting the intertidal and subtidal zones of the Sao Sebastiao Channel, Brazil, between 2010 and 2012, with identified species belonging to 52 species of 34 genera grouped in 18 families.
Gastropoda (Mollusca) associated to Sargassum sp beds in Sao Sebastiao Channel - Sao Paulo, Brazil
TLDR
The presence of juvenile specimens was recurrent, this indicating that the algae can function as a nursery for most of these species, and illustrate the great ecological importance of the phytal habitats for the gastropod species.
