The ingestion of plastic debris by marine organisms has been documented across a variety of taxa including; marine mammals, sea birds, sea turtles and some fish species. Fewer reports have described ingestion by sharks, in this study the gastrointestinal tracts of 20 small spotted catsharks (Scyliorhinus canicula) trawl captured in the North Sea were investigated. Macroplastics (>20 mm) were found in 2 individuals and microplastic (<5 mm) was found in one other individual, this is the first time that plastic ingestion has been reported in this species. These observations suggest that gastrointestinal analysis of commonly landed elasmobranch species is worthwhile, to further understanding on the organisms and habitats impacted by plastic pollution.
海洋生物摄入塑料碎片的情况已在包括海洋哺乳动物、海鸟、海龟和一些鱼类物种在内的多种分类群中得到记录。关于鲨鱼摄入塑料碎片的报道较少，在这项研究中，对北海水域捕捞的 20 条小星鲨（Scyliorhinus canicula）的胃肠道进行了调查。在 2 个个体中发现了大塑料碎片（>20 毫米），在另一个个体中发现了微塑料（<5 毫米），这是首次在该物种中报告摄入塑料的情况。这些观察结果表明，对常见上岸的鲛鱼类物种进行胃肠道分析是值得的，这有助于进一步了解受塑料污染影响的生物和栖息地。
