Coastal ecosystems of northeastern Brazil have important biodiversity with regard to marine mollusks, which are insufficiently studied. Here we provide an inventory of mollusks from two sites in the estuary of the Paraíba River. Mollusks were collected in 2014 and 2016 on the coast and sandbanks located on the properties of Treze de Maio and Costinha de Santo Antônio. The malacofaunal survey identified 12 families, 20 genera and 21 species of bivalves, 17 families, 19 genera and 20 species of gastropods and one species of cephalopod. Bivalves of the family Veneridae Rafinesque, 1815 were the most representative, with a total of five species. Gastropods of the family Littorinidae Children, 1834 had the greatest species richness. The most abundant species were: Neritina virginea (Linnaeus, 1758), Brachidontes exustus (Linnaeus, 1758), Crassostrea brasiliana (Lamarck, 1819), Cerithium atratum (Born, 1778), Anomalocardia brasiliana (Gmelin, 1791), Parvanachis obesa (C. B. Adams, 1845), Phrontis polygonata (Lamarck, 1822), Littoraria angulifera (Lamarck, 1822), L. flava (King, 1832), Tagelus plebeius (Lightfoot, 1786), Echinolittorina lineolata (d'Orbigny, 1840) and Iphigenia brasiliensis (Lamarck, 1818). The results show that the study area has considerable species richness of Mollusca, requiring environmental monitoring in the region mainly due to the economic importance of some species to the local population.

“…The organisms were collected from the intertidal zone, where they live buried under sandy and muddy sediments (Tallarico et al 2014). Specimens were removed from the sediment with a shovel, manually sorted using a sieve and immersed in sea water, transported and processed at the Centre of Marine Biology, University of São Paulo (CEBIMar-USP).…”

Spermatozoan ultrastructure and mitochondrial gene sequence ofCaryocorbula caribaea(d'Orbigny, 1853) (Corbulidae: Bivalvia), a species with plasticity in shell morphology

Systematics of Corbulidae supported by anatomical and conchological studies remains confused and controversial because of the considerable phenotypic plasticity of their shells. Ultrastructural spermatozoan study and molecular analyses have been performed to contribute valuable information, which could be used in taxonomy. Electron microscopy was used to analyse sperm cells from specimens of Caryocorbula (Gardner, 1926) exhibiting shell differences. The spermatozoon was of the aquasperm type, showing short acrosome, barrel-shaped nucleus, midpiece composed of four spherical mitochondria and simple flagellum. In addition, about 860 base pairs of mitochondrial large ribosomal subunit (16S rRNA) were sequenced from each individual. The consistent similarity shared by spermatozoa and DNA sequences from all studied specimens indicated that they belonged to one coherent unit, Caryocorbula caribaea (d'Orbigny, 1853), despite the extraordinary plasticity exhibited by their shells.

“…Most species are now restricted to relatively limited geographic ranges and have specialized niches being, therefore, considered a group of rare species (Coan & Valentich‐Scott, ; Harper, Dreyer, & Steiner, ; Harper, Hide, & Morton, ; Morton, ). Species from the families Cuspidariidae, Pandoridae, Periplomatidae and Thraciidae have been recorded from the northern coast of São Paulo state, in southeastern Brazil (Amaral & Nallin, ; Migotto, Tiago, & Magalhães, ; Salvador, Domaneschi, Amaral, Morgado, & Henriques, ; Soares‐Gomes & Pires‐Vanin, ; Tallarico et al, ).…”

Ultrastructure of the spermatozoa of three species of Anomalodesmata (Mollusca, Bivalvia) and phylogenetic implications

Anomalodesmata is the rarest and most specialized group of the class Bivalvia. In general, scarce data on sperm ultrastructure of anomalodesmatans are available in the literature. Aiming to contribute to an understanding of spermatozoon morphology in this group, the present study describes the ultrastructure of male gametes of three species—Cardiomya cleryana (Orbigny 1842) (Cuspidariidae), Pandora brevirostris Güller and Zelaya 2016 (Pandoridae) and Thracia similis Couthouy 1839 (Thraciidae). C. cleryana has an acrosome located at the anterior region, and the mitochondria are symmetrically arranged, while the spermatozoa of P. brevirostris and T. similis have unique characteristics, in particular the association of the acrosome with the midpiece and asymmetric mitochondria. This position of the acrosome appears to be peculiar among Anomalodesmata and is unknown for non‐anomalodesmatan bivalves. The present ultrastructural description of spermatozoa contributes to differentiate the studied species, bringing new insights about the sperm features of anomalodesmatan species and shares several characteristics with that of other species of the two lineages proposed by molecular phylogeny.
