Over the past fifty years, interactions between anthropogenic debris and a wide range of marine species have increased. In cetaceans, the most frequent interactions have occurred through ingestion and/or entanglement, with results ranging from minor injuries to death in affected animals. While debris ingestion is widely documented in odontocetes, records are scarcer in mysticetes. This study describes the finding of plastic litter in the digestive tract of a southern right whale (Eubalaena australis) juvenile male, which was found dead on the shores of Golfo Nuevo, Chubut, Argentina in 2014. During the examination of intestinal contents, anthropogenic waste was found and classified as macro-debris (25 mm-1 m). Although this whale likely died of causes not related to this finding, it is the first record of anthropogenic debris ingestion for this species. This event adds information about the potential impact of human-made debris on a variety of aquatic species and ecosystems.
在过去的五十年中，人为垃圾与各种海洋物种之间的相互作用不断增加。在鲸目动物中，最常见的相互作用是通过摄入和/或缠绕而发生的，结果从受影响动物的轻微受伤到死亡不等。虽然在齿鲸类中广泛记录了垃圾摄入，但在须鲸类中记录较少。本研究描述了在一只南露脊鲸（Eubalaena australis）幼年雄性的消化道中发现塑料垃圾的情况，该鲸鱼于 2014 年在阿根廷丘布特省的新湾（Golfo Nuevo）海滩上死亡。在检查肠内容物时，发现了人为废物，并将其分类为大碎片（25 毫米-1 米）。尽管这头鲸鱼可能死于与这一发现无关的原因，但这是该物种摄入人为垃圾的首例记录。这一事件增加了有关人造碎片对各种水生物种和生态系统的潜在影响的信息。
