Anthropogenic debris has been documented in Antarctica for the past 40 years. Upon breakdown, large pieces become microdebris, which reaches seafloor through a variety of physical and biological processes. The Antarctic benthos, deeply reliant on sinking organic particles, is thus vulnerable to ingesting microdebris. By using benthic specimens sampled between 1986 2016 deposited collections, we provide first record microdebris Southern Ocean deep-sea invertebrates. Specimens from 15 species (n = 169 organisms) had their gut content examined, with 13 yielding shape fibers 85 fibers). highest ingestion percentages were recorded sea cucumbers Heterocucumis steineni (100%), Molpadia violacea (83%) Scotoplanes globosa (75%), brittle star Amphioplus peregrinator (53%). Deposit- suspension-feeding strategies yielded most fibers, accounting 83.53% particles. Seven identified as microplastics, composed polyamide, polycarbonate, polyester, polyethylene terephthalate, polyisoprene polysulfone. We also earliest microplastic Antarctica, polysulfone fiber ingested by Boreomysis sp. mysid caught 1986. occurrence world's remote continental margin renews concerns pollution seemingly isolated regions.
