Several studies have been conducted on the richness and abundance of molluscs in the coastal coral reefs of the Gulf of Mexico since 1960's, but these have focused mainly on knowledge of prosobranch gastropods and bivalves species, while only 6 species of opisthobranchs have been registered for this ecosystem. In this paper we present a list of 23...

The microbialization of coral reefs predicts that microbial oxygen consumption will cause reef deoxygenation. Here we tested this hypothesis by analyzing reef microbial and primary producer oxygen metabolisms. Metagenomic data and in vitro incubations of bacteria with primary producer exudates showed that fleshy algae stimulate incomplete carbon ox...
In this study we investigate the development of the nervous system in scallop Amusium balloti by immunocytochemistry, using an anti-5HT (serotonin) antibody and laser scanning confocal microscopy. Serotonin expression in the scallop larval central nervous system (CNS) appears to be transient and ceases during the metamorphosis. All three major gang...
As regiões estuarinas da costa brasileira são caracterizadas como áreas de extrativismo de moluscos, especialmente bivalves, muito apreciados na alimentação. Iphigenia brasiliana é um bivalve comestível apenas em alguns estados brasileiros, embora tenha grande potencial comercial. Neste trabalho, foram descritas as variações temporais na biometria...
The inner layer of many bivalve and gastropod molluscs consists of iridescent nacre, a material that is structured like a brick wall with bricks consisting of crystalline aragonite and mortar of organic molecules. Myostracal layers formed during shell growth at the point of muscle attachment to the shell can be found interspersed within the nacre s...

The seaslugs Berghia rissodominguezi Muniain y Ortea, 1999 and Phidiana lynceus Bergh, 1867 are recorded for the first time for the east coast of Mexico and the coasts of Veracruz, Mexico, respectively.
Little is known about the seaslugs in the Mexican coast of the Gulf of Mexico and almost all the species reported are either large or have a well-developed calcareous shell. Through specific sampling methods focused in opisthobranchs fauna, in two lagoons and three coral reefs of the Campeche Bank, Yucatan Peninsula, we have recorded 51 species belonging to the clades Cephalaspidea, Aplysiomorpha, Sacoglossa, Eutenidiacea, and Cladobranchia. Of these, 30 species had not been previously reported for the Campeche Bank and 20 out of those are new records for the Atlantic coast of Mexico. The nudibranch Tambja cf. tenuilineata could be the first record for the east coast of the Atlantic Ocean. With this study, the actual number of opisthobranch fauna in the Campeche Bank are 84 species.
