Benthic zebra sharks can preserve microplastic fibers from decades ago, acting as sediment archives.
Zebra sharks, slow-moving bottom dwellers in tropical deep-sea habitats, have been found with microplastic fibers in stomach and dermal tissues. Analysis shows fibers dating back decades, revealing persistent pollution even in seemingly isolated seafloor zones. These sharks ingest microplastics through contaminated prey or sediment-laden water. Their slow metabolism allows fibers to persist over long periods, acting as biological archives. Researchers highlight that benthic species like zebra sharks record historical human impact in ways previously underappreciated. Studying these sharks provides insights into sediment-borne microplastic transfer and benthic ecosystem contamination. Findings challenge assumptions that sedentary species are insulated from long-term pollution. Microplastic presence in zebra sharks underscores the hidden reach of synthetic debris across habitats. The data emphasizes the role of benthic megafauna as sentinel species.

Zebra sharks serve as indicators of long-term benthic contamination. Students can explore benthic species as microplastic archives. Conservationists can monitor these sharks to track historical and ongoing pollution. Outreach programs can safely illustrate sediment-borne debris accumulation. Highlighting zebra sharks emphasizes hidden ecological footprints of human activity. Public interest grows when slow-moving species reveal decades of contamination. Conservation strategies may integrate benthic predator monitoring for ecosystem assessment.
Fibers in zebra shark tissues inform trophic transfer and sediment interaction studies. Archival and field research shows temporal persistence of debris. Educational programs can safely explore contamination in benthic megafauna. Conservation planning benefits from including bottom-dwelling giants in monitoring strategies. Studying zebra sharks highlights the subtle yet pervasive ecological impact of microplastics. Findings underscore how sedentary species archive decades of human activity. It emphasizes the need for long-term benthic pollution monitoring programs.
