Drillholes on shells are one of the few predation marks preserved in fossil molluscs, providing an opportunity to study and quantify predator-prey interactions in the palaeontological record. Among these, reports of drilling predation on scaphopods are rare, and such information from Antarctica is non-existent. We describe the finding of drillholes on scaphopods recovered from Recent mollusc assemblages between depths of 246.5 and 454.0 m in West Antarctica. The predation traces located in the middle sectors of two preyed shells belonging to Siphonodentalium dalli and Dentalium majorinum are identified as Oichnus and are interpreted as produced by naticids, probably Pseudamauropsis aureolutea. These new records constitute the first reports of drilling predation on scaphopods in Antarctica and also for Recent scaphopods of the Southern Hemisphere.

对南极象牙贝壳的钻探捕食：南半球近期舟足类动物的首次记录

贝壳上的钻孔是软体动物化石中为数不多的捕食标记之一，为研究和量化古生物学记录中捕食者与猎物之间的相互作用提供了机会。其中，关于钻捕捕食的报道很少见，南极洲的此类信息也不存在。我们描述了在南极洲西部 246.5 至 454.0 m 深度之间从最近的软体动物组合中回收的舟足类动物上的钻孔发现。捕食痕迹位于两个被捕食的贝壳的中部，属于大虹吸虫和大牙菌被识别为奥伊克努斯并被解释为由海栖动物产生的，可能金黄色葡萄球菌. 这些新记录构成了关于在南极洲以及最近的南半球水手纲上捕食钻探捕食的第一份报告。
