Observations of killer whales (Orcinus orca) feeding on the remains of beaked whales have been previously documented; however, to date, there has been no published account of killer whales actively preying upon beaked whales. This article describes the first field observations of killer whales interacting with, hunting and preying upon beaked whales (Mesoplodon spp.) on four separate occasions during 2014, 2015 and 2016 in the Bremer Sub-Basin, off the south coast of Western Australia.
此前已有关于虎鲸以喙鲸残骸为食的观察记录；然而，迄今为止，尚未有关于虎鲸主动捕食喙鲸的公开报道。本文描述了2014年、2015年和2016年期间，在西澳大利亚州南海岸外的布雷默次区域，虎鲸在四个不同场合与喙鲸（中喙鲸属物种）互动、捕猎和捕食的首次实地观察情况。
