ClearGooseneck barnacles ( Lepas spp.) ingest microplastic debris in the North Pacific Subtropical Gyre
Researchers examined the gut contents of gooseneck barnacles (Lepas spp.) collected from floating debris in the North Pacific Subtropical Gyre and found that all individuals had ingested microplastic particles. The findings demonstrate that suspension-feeding invertebrates colonizing floating plastic debris are directly exposed to and ingest microplastics, representing a pathway for plastic entry into open-ocean food webs.
Microplastic ingestion by pelagic gooseneck barnacles (Lepas spp.) and other insights on their biology and ecology in the South Pacific Ocean
This study examined microplastic ingestion by pelagic gooseneck barnacles (Lepas spp.) in the South Pacific Ocean, species considered highly capable of microplastic ingestion among rafting organisms. Microplastics were found in barnacles across sampling sites, and the study provided ecological context for understanding the role of rafting organisms in concentrating and transporting plastic pollution in open-ocean ecosystems.
Ingestion of Microplastics by Zooplankton in the Northeast Pacific Ocean
Researchers collected zooplankton from the northeast Pacific Ocean and found microplastics ingested by multiple species, demonstrating that microplastic uptake occurs throughout the open ocean zooplankton community far from coastlines.
Relative Abundance of Floating Plastic Debris and Neuston in the Eastern North Pacific Ocean
Researchers examined the relative abundance of floating plastic debris versus neuston organisms in the Eastern North Pacific Ocean, finding significant knowledge gaps in understanding how accumulating plastic in subtropical gyres affects surface-associated marine life. The study argues that removing floating debris is necessary to prevent harm to neuston communities and limit secondary microplastic formation.

Researchers examined gooseneck barnacles collected from a marine protected area in the Tyrrhenian Sea and found microplastics and synthetic fibers in nearly a third of them, suggesting these filter-feeding organisms could serve as inexpensive, widely distributed biological indicators for monitoring microplastic contamination in coastal waters.
Towards the suitable monitoring of ingestion of microplastics by marine biota: A review
This review assessed various monitoring methods for detecting microplastic ingestion by marine biota, comparing laboratory and field-based approaches. The authors recommend method selection based on organism type and research question and call for more consistent reporting standards to enable cross-study comparison.
Peer Review #1 of "Microplastic ingestion by commercial marine fish from the seawater of Northwest Peninsular Malaysia (v0.2)"
This peer review evaluates a revised version (v0.2) of a study on microplastic ingestion by four commercial marine fish species from Northwest Peninsular Malaysia, where all 72 sampled fish guts contained microplastics totaling 432 particles across species. The reviewer assesses the adequacy of revisions addressing earlier concerns about methodology and the significance of findings for Malaysian food safety given the dietary importance of these fish.
Peer Review #2 of "Microplastics do not affect bleaching of Acropora cervicornis at ambient or elevated temperatures (v0.1)"
This peer review provides a second independent evaluation of a study examining whether microplastic pollution affects bleaching in Acropora cervicornis coral at ambient or elevated temperatures, contributing to rigorous assessment of microplastic impacts on coral reef organisms.
In situ microplastic ingestion by neritic zooplankton of the central Mexican Pacific
Researchers documented in situ microplastic ingestion by zooplankton in two bays of the central Mexican Pacific, finding that copepods, decapod larvae, and chaetognaths ingested microplastics, predominantly fibers, with higher rates during the rainy season.
Sources, fate and effects of microplastics in the marine environment: part 2 of a global assessment
This second part of a major GESAMP review on microplastics in the marine environment examined sources, fate, and effects, providing a comprehensive scientific assessment of the state of evidence and priority research needs.
Non-selective feeding on microplastics in the acorn barnacle Amphibalanus amphitrite: the implications in assessing barnacles as global microplastics bioindicators
Researchers studied microplastic ingestion by striped barnacles (Amphibalanus amphitrite) by exposing them to three plastic types, two sizes, and two concentrations, with and without biofilm coatings. Barnacles ingested microplastics non-selectively regardless of type or biofilm status, confirming them as useful bioindicators of plastic pollution in marine environments.
Assessing size-based exposure to microplastic particles and ingestion pathways in zooplankton and herring in a coastal pelagic ecosystem of British Columbia, Canada
Researchers assessed size-based microplastic exposure and ingestion pathways in zooplankton and larval Pacific herring in British Columbia's coastal waters, finding evidence of both direct consumption and trophic transfer of microplastics through the pelagic food web.
Barnacles as emerging sentinels of microplastic contamination: A global synthesis and analytical framing
Barnacles — the small crustaceans that encrust ship hulls and rocky shores — filter seawater continuously, making them promising sentinels for detecting microplastic pollution levels in the ocean. This global review of 14 field studies across seven countries found that barnacles consistently reflect local microplastic contamination, with fibers and fragments of polyethylene and cellophane being most common. While barnacles show real potential as low-cost monitoring organisms, the authors call for standardized methods to make data from different regions and studies comparable.
Fate of Nanoplastics in Marine Larvae: A Case Study Using Barnacles, Amphibalanus amphitrite
Researchers tracked the fate of nanoplastics in barnacle larvae, finding that these tiny particles were ingested and could accumulate in larval tissues, with potential implications for early development and survival of marine invertebrates.
Review: Environmental toxicology of marine microplastic pollution — R0/PR3
This is a third peer review document associated with the same marine microplastic toxicology review, which covers bioaccumulation and biological effects of microplastics across multiple marine organism groups. The review it supports is a significant synthesis of evidence on how microplastics harm marine ecosystems. As a peer review artefact, it is not original research but reflects the rigour applied to publishing key microplastics science.
Experimental accumulation of microplastics in acorn barnacle Amphibalanus amphitrite and its use in estimating microplastic concentration in coastal waters
Researchers assessed the potential of acorn barnacles (Amphibalanus amphitrite) as bioindicators for microplastic pollution, finding that these filter feeders accumulate polypropylene fibers and fragments in ways that could help estimate coastal water contamination levels.
Microplastic pathways in marine pelagic systems
This review examines how microplastics move through open-ocean (pelagic) ecosystems and what effects they might have on sea life. The authors conclude that clear evidence of harm in pelagic species is still limited, and well-designed cause-and-effect studies are needed to draw firmer conclusions about environmental risk.
Pelagic microplastics in the North Pacific Subtropical Gyre: A prevalent anthropogenic component of the particulate organic carbon pool
This study measured microplastic concentrations in the water column of the North Pacific Subtropical Gyre and found that fossil-based microplastics make up a significant fraction of the particulate organic carbon pool, with implications for ocean biogeochemical carbon cycling and export.
