Previous studies on the mollusks from Brazilian underwater canyons have addressed the record and description of new species of aplacophorans, bivalves, scaphopods and/or gastropods (Leal & Simone 2000; Absalão 2010; Corrêa et al. 2014). Leal & Simone (2000) described a new bathyal gastropod of the family Pseudococculinidae collected from the continental slope and Doce River Canyon (960 m) off the state of Espírito Santo (southeastern Brazil). Absalão (2010) reported a number of species of gastropods, bivalves and scaphopods from Campos Basin off the state of Rio de Janeiro (southeastern Brazil). It is likely that some of these species reported by Absalão (2010) were collected from underwater canyons in the northern portion of the Campos Basin. Corrêa et al. (2014) recorded two species of aplacophorans of the genus Falcidens Salvini-Plawen, 1968 obtained from the continental slope and underwater canyons of Campos Basin. Certainly more species of mollusks were studied from Brazilian underwater canyons, but not duly mentioned in publications (i.e., the region of canyons may have been referred to as the continental slope or deep sea).
此前对巴西水下峡谷软体动物的研究涉及无板纲动物、双壳类、掘足纲动物和/或腹足纲动物新物种的记录与描述（Leal & Simone，2000年；Absalão，2010年；Corrêa等人，2014年）。Leal & Simone（2000年）描述了一种采自圣埃斯皮里图州（巴西东南部）大陆坡和多西河峡谷（960米）的新深海腹足纲假球壳科动物。Absalão（2010年）报告了里约热内卢州（巴西东南部）坎波斯盆地的一些腹足纲、双壳类和掘足纲动物物种。Absalão（2010年）报告的这些物种中，有些可能是从坎波斯盆地北部的水下峡谷采集的。Corrêa等人（2014年）记录了1968年从坎波斯盆地大陆坡和水下峡谷获得的两种镰齿无板纲动物。当然，巴西水下峡谷研究的软体动物物种更多，但在出版物中未得到适当提及（即峡谷区域可能被称为大陆坡或深海）。
