Few studies focused on behaviour adaptations of organisms to marine litter (ML) pollution in Mediterranean Sea. This research, investigates on some behavior traits of Octopus vulgaris, focusing on the interaction with ML during the artisanal fishing activities by the bottom traps in a small coastal area of the southern Tyrrhenian Sea. For the first time, this pilot study uses an integrated approach based on the Fishermen Ecological Knowledge as well as the analysis of ML found in the traps. First assessment of plastic ingestion in this species are also reported.

Plastic and metal were the predominant ML categories observed into the bottom traps. A total of 62 plastics, mainly small microplastics and fibres shaped, were ingested. The ML finding in the bottom traps suggests an interesting behavior of the common octopus regarding its interaction with ML, in fact, it seems to bring ML inside its dens, as a collector.

很少有研究关注生物对地中海海洋垃圾 (ML) 污染的行为适应。本研究调查了普通章鱼的一些行为特征，重点是在第勒尼安海南部一个小沿海地区的底部诱捕器的手工捕鱼活动中与 ML 的相互作用。这项试点研究首次使用基于渔民生态知识的综合方法以及对陷阱中发现的 ML 的分析。还报告了对该物种摄入塑料的首次评估。

塑料和金属是在底部陷阱中观察到的主要 ML 类别。总共摄入了 62 种塑料，主要是小型微塑料和纤维状。ML 在底部陷阱中的发现表明了普通章鱼在与 ML 交互方面的有趣行为，事实上，它似乎将 ML 作为收集器带入了它的巢穴。
