| Of the analysis of five rocky areas in the intertidal zone of the Esmeraldas province: Tachina, Balao, Súa-Atacames, Galera and Mompiche, from the limit of the high tide to the limit of the low tide, were founded nine (9) species of drilling bivalves molluscs, that belong to three families: Mytilidae, Petricolidae and Pholadidae. Petricola denticulata was the most abundant species in the Esmeraldas province and represents the 26.1% among all species, whiles the sites or stations that were observed the greater abundance of organisms were Balao and Súa-Atacames with 39.1% each one. The greater richness of species was observed in Súa-Atacames, having reprsented 50% of the total diversity. In Tachina station, drilling rock organism were not observed. The... |

| La Tunisie dispose d’une ressource importante en coquillages, plusieurs espèces sont commercialisées et elles ont fait l’objet de programmes de qualité pour la sauvegarde de la santé humaine. Dans ce contexte, nous avons réalisé un suivi saisonnier de la concentration de trois métaux traces toxiques, le cadmium (Cd), le plomb (Pb), et le mercure (Hg) dans la totalité de la masse molle, dans le pied et dans les viscères d’un Mollusque Gastéropode, l’Hexaplex trunculus communément appelé en Tunisie « Bakouma ». Les Hexaplex proviennent des golfes de Tunis et de Gabès et des lagunes de Bizerte et de Tunis durant la période 2003 - 2004. Les échantillons sont analysés par spectrométrie d’absorption atomique (SAA) à four graphite et à correction Zeeman (Varian... |

| Del análisis de más de 90 muestreos realizados en la zona intermareal rocosa en 33 sitios de la costa Ecuatoriana, desde el año 2000 al 2005, se identificaron cuatro especies de moluscos bivalvos perforadores de rocas de la familia Mytilidae: Gregariella coarctata, Lithophaga aristata, Lithophaga (L) attenuata y Lithophaga hastasia. Lithophaga hastasia, es considerada "rara" está restringida para Perdenales-Chorrera en la Provincia de Manabí, no se volvió a encontrar en otro lugar de la costa Ecuatoriana, prefiriendo un ecosistema influenciado por aguas tropicales provenientes del norte del país. La especie Gregariella coarctata, se la considera "Común" prefiere la Provincia de Manabí entre Punta Bellaca y Manta, puede extenderse hacia el sur del Ecuador... |

| Gadila elongata comb. nov. was described in 1920 from the northern Gulf of Mexico. Until recently, it was only known from the type locality. Herein we present the first record of G. elongata from Brazil (Northeast coast, Ceará state, collected at 177 m) and a morphometrics analysis of the Brazilian species of Gadila. A multivariate Discriminant Function Analysis, based on nine shell morphometric variables (length, maximum diameter, length to maximum diameter ratio, distance of point of maximum diameter from anterior aperture, maximum curvature, anterior aperture height to anterior aperture width ratio, apical aperture height, apical aperture width and apical aperture height to apical aperture width ratio) enabled the distinction between all species... |
