Marine PlasticDebris Entrapped in Tube Decorationsof Plumed Worm: Evidence of a Novel Biological Sink in IntertidalMudflats
AI summary Read the abstract
Scientists found that tiny worms living in coastal mudflats build their protective tubes using plastic fibers—mostly bits of old fishing nets and lines—collecting far more plastic than what's found in the surrounding sand or inside other sea creatures that eat plastic by accident. This matters because these worms are unknowingly acting as pollution traps, meaning standard water and sediment testing may be missing large amounts of plastic hiding in coastal ecosystems—plastic that can work its way up the food chain and eventually onto our plates.
Marine plastic pollution research has focused primarily on debris in water columns and sediments, as well as plastics ingested by marine organisms, while the incorporation of plastics into biogenic structures by habitat-engineering organisms remains underexplored. Here, we investigated the tube-decorating polychaete Diopatra sp. on intertidal mudflats of Hanagae Beach, South Korea, to assess whether plastic debris is utilized as tube-building material. While no plastic particles (> 2 mm) were detected in surface sediments, all examined Diopatra tubes (n = 48) contained plastics, averaging 4.73 plastic particles per tube. Both Diopatra abundance and tube-entrapped plastics increased with distance from the shoreline, suggesting hydrodynamic mediation of habitat suitability and plastic retention. FTIR spectroscopy revealed that fibers dominated the incorporated plastics, primarily derived from Abandoned, Lost, or otherwise Discarded Fishing Gear (ALDFG). Notably, per-tube plastic loads substantially exceeded ingestion-based accumulation levels reported for other benthic invertebrates, underscoring bioconstruction as a distinct and more efficient retention mechanism. We propose that, at least within intertidal systems, tube-decorating polychaetes may act as a biological reservoir for plastic debris through tube construction, whereby their biogenic structures can reflect pollution levels that may be overlooked by conventional sampling approaches.

Marine Plastic Debris Entrapped in Tube Decorations of Plumed Worm: Evidence of a Novel Biological Sink in Intertidal Mudflats
AI summary Read the abstract
Scientists studying mudflats in South Korea found that a marine worm called Diopatra builds its protective tubes using plastic fibers—mostly bits of old fishing gear—instead of natural materials, with every single tube tested containing plastic. Surprisingly, these tubes held far more plastic than what's typically found by measuring the surrounding mud or in other animals that eat plastic by accident, meaning current testing methods may be missing a lot of plastic pollution hiding in coastal ecosystems. Since these mudflats are part of the food chain that eventually connects to seafood on our plates, this finding matters for understanding
Quantitative evaluation of microplastics in colonies of Phragmatopoma caudata Krøyer in Mörch, 1863 (Polychaeta-Sabellariidae): Analysis in sandcastles and tissues and identification via Raman spectroscopy
AI summary Read the abstract
Researchers found microplastics embedded in the sand tubes and body tissues of Phragmatopoma caudata, a tube-building marine worm that constructs its home from sand grains. This study shows that filter-feeding and sediment-associated organisms incorporate microplastics into their structures, spreading plastic contamination through marine ecosystems.

This short study documented for the first time that the tube-building polychaete worm Diopatra cuprea incorporates plastic debris into the caps of its tubes in a Brazilian estuary. This interaction shows how marine organisms adapt to polluted environments and represents a novel pathway for plastic incorporation into marine habitats.
Abundance of microplastic in different coastal areas using Phragmatopoma caudata (Kroyer in Morch, 1863) (Polychaeta: Sabelariidae) as an indicator
AI summary Read the abstract
Researchers used reef-building worms (Phragmatopoma caudata) as biological indicators to compare microplastic contamination across different coastal areas in Brazil. By analyzing the worms' tube structures and surrounding sediment, they found varying levels of microplastics that reflected local pollution sources. The study suggests these filter-feeding organisms can serve as practical tools for monitoring microplastic pollution along coastlines.

Researchers used the reef-building polychaete Phragmatopoma caudata as a bioindicator to assess microplastic abundance across different coastal areas of Brazil. They found that filter-feeding and suspension-feeding organisms like this tube worm incorporate microplastics from their environment, making them useful monitors of coastal plastic pollution.
