Mollusks from two estuarine areas in Ceará state, northeastern Brazil, with new state records for four species
We analyzed qualitatively the malacofauna found in the tidal zones of Banco dos Cajuais and Ilha Grande estuarine complex, both in Ceara State, northeastern Brazil. Qualitative data on theExpand
Imposex in endemic volutid from Northeast Brazil (Mollusca: Gastropoda)
Imposex is characterized by the development of masc uline sexual organs in neogastropod females. Almost 120 mollusk species are known to present imposex when eto organic tin compounds as tributyltinExpand
Thais (Stramonita) rustica (Lamarck, 1822) (Mollusca: Gastropoda: Thaididae), a potential bioindicator of contamination by organotin northeast Brazil
The use of antifouling paints containing the biocide compound tributyltin (TBT) has been shown as an inductor of imposex in neogastropods mollusks. Imposex is characterized by the development of maleExpand
RELATIONS BETWEEN SHELL SIZE AND RADULA SIZE IN MARINE PROSOBRANCHS (MOLLUSCA: GASTROPODA)
The Gastropoda presents the highest adaptative radiation among the mollusks. This characteristic allowed the appearance of many forms of feeding, and with it, many strategies of capture and foodExpand
Spawn and larval development of Pleuroploca aurantiaca (Lamarck, 1816) (Gastropoda: Fasciolariidae) from Northeast Brazil
Spawn and larval development stages of Pleuroploca aurantiaca from northeast Brazil are described. The reproductive period lasted from August to December, with a peak in November. Spawn masses wereExpand
A first record of biphallia in imposexed female of Leucozonia nassa (Caenogastropoda: Fasciolariidae)
Imposex is characterized by the development of male characteristics, such as the penis and vas deferens, in female prosobranch gastropods, caused by organotin compounds contamination. In Brazil,Expand
The Increasing Incidence of Imposex in "Stramonita haemastoma" (Mollusca: Gastropoda: Muricidae) after the Estaqblishment of the Pecém Harbor, Ceará State, Northeast Brazil
Imposex is characterized by the development of masculine sexual organs in neogastropod females, caused by organotin contamination of the seawater. These compounds, as tributyltin (TBT), are usedExpand
PREY PREFERENCE AND PREDATORY BEHAVIOR OF Aurantilaria aurantiaca (MOLLUSCA: GASTROPODA: FASCIOLARIIDAE)
Fasciolariid species are predators that prey on other gastropods and bivalves. They usually break prey shell to reach its soft parts. In this study, prey species that Aurantilaria aurantiaca consumesExpand
