Comparative microplastic (MP) data for cephalopods between oceans is scarce. Our aim was to quantify, characterise, and compare MPs in gills, digestive gland, and mantle of chokka squid from the South Atlantic Ocean (SAO) and Indian Ocean (IO) off the coast of South Africa. South African squid had more MPs compared with other studies (means = 2.0 and 0.4 in SAO and IO squid mantle, respectively). Blue fibres were dominant. Identifiable MPs were polyethylene. Despite IO water having higher MP concentrations than the SAO, SAO squid had higher MP concentrations. Dilution by growth is the likely reason for the lower MP concentrations. Fibres were shorter in SAO than IO squid. However, we could not explain why fibre and mantle lengths from both oceans were positively correlated. Squid may not be the best indicator of marine MPs. The characteristics of MPs in squid can be used to track stocks and migrations.

印度洋和南大西洋中的微塑料转移到了 chokka 鱿鱼 Loligo reynaudii 的鳃、消化腺和肌肉中

海洋之间头足类动物的微塑料（MP）比较数据很少。我们的目的是量化、表征和比较南非海岸南大西洋 (SAO) 和印度洋 (IO) 的乔卡乌贼的鳃、消化腺和外套膜中的 MP。与其他研究相比，南非鱿鱼具有更多的 MP（SAO 和 IO 鱿鱼外套膜的平均值分别为 2.0 和 0.4）。蓝色纤维占主导地位。可识别的 MP 是聚乙烯。尽管IO水具有比SAO更高的MP浓度，但SAO鱿鱼具有更高的MP浓度。生长稀释可能是 MP 浓度较低的原因。 SAO 鱿鱼的纤维比 IO 鱿鱼短。然而，我们无法解释为什么两个海洋的纤维和地幔长度呈正相关。鱿鱼可能不是海军陆战队员的最佳指标。鱿鱼中 MP 的特征可用于追踪种群和迁徙。
