Zusammenfassung:Imposex is is a well-documented deleterious effect caused by tributyltin (TBT) in females of hundreds of Caenogastropoda species and it is a well-established way of predicting BTs occurrence in marine systems. This study presents the very first information on the presence and distribution of imposex in Stramonita brasiliensis (Claremont and Reid, 2011) in the Brazilian Legal Amazon, within a Ramsar site, during a 6-year appraisal after the TBT global ban in 2008 (2012–2017). Imposex was evidenced in six out of the seven sampling sites, with 39.7% of the total affected females, most of them showing VDSI
