Velvet rays can retain microplastic fibers from decades of contamination, acting as benthic archives.
Velvet rays, inhabiting benthic deep-sea zones, have microplastic fibers lodged in muscle and stomach tissues. These fibers are ingested through contaminated prey and sediment interactions. Analysis shows fibers dating back decades, revealing persistent contamination even in low-mobility species. Velvet rays’ tissues act as biological archives, preserving records of human impact over time. Researchers highlight that even specialized benthic species are affected by microplastic infiltration. Studying these rays provides insight into sediment-borne pollutant transfer to predators. Findings underscore that all deep-sea giants, regardless of mobility or habitat, archive human pollution. The persistence of microplastics in rays emphasizes the long-term ecological consequences of synthetic debris. Deep-sea ecosystems are interconnected, and even seemingly isolated species reveal decades of contamination.

Microplastic accumulation in velvet rays informs benthic ecosystem health. Students can explore bioaccumulation in low-mobility species. Conservationists can monitor rays to track historical and ongoing contamination. Outreach programs can safely demonstrate persistent human impact in sediments. Highlighting rays emphasizes the ecological connectivity of benthic and pelagic zones. Public engagement grows when slow-moving giants reveal hidden pollution. Conservation strategies may include benthic monitoring for long-term ecosystem assessment.
Fibers in velvet rays provide insight into trophic transfer and ecosystem persistence. Archival and field studies reveal decades of contamination. Educational programs can safely simulate benthic bioaccumulation. Conservation planning benefits from monitoring low-mobility deep-sea species. Studying rays highlights the subtle but pervasive ecological impacts of human debris. It demonstrates that even isolated habitats archive human environmental influence. Findings emphasize the importance of including benthic species in pollution monitoring strategies.
