ClearPreliminary Report of Microplastic (MPs) Presence on East Java Freshwater Sponges at Brantas Porong River
Freshwater sponges (Oncosclera asiatica) from the Brantas Porong River in East Java were examined for microplastic contamination, representing a preliminary study of microplastics in a rare and understudied freshwater organism. As filter feeders, the sponges accumulated microplastics from the surrounding water, with physical characteristics of the particles characterized.
Seagrass sponge (Agelas conifera: Demospongia) potential of microplastic accumulation from Pramuka Island, Seribu Islands
Marine sponges collected from a tourist island near Jakarta accumulated 167-300 microplastic particles per gram of tissue, considerably more than were found in surrounding water or sediment. The findings show sponges can concentrate microplastics from their environment, making them useful biological indicators of pollution.
Sponges as bioindicators for microparticulate pollutants?
This study investigated whether sponges can serve as bioindicators of microparticle pollution in coral reef environments, finding that sponges incorporate foreign particles including microplastics from the surrounding water. Sponges could be useful sentinel organisms for monitoring microplastic contamination in reef ecosystems given their extensive filter feeding.

Researchers found potential microplastics in the tissues of six Caribbean sponge species from Bocas del Toro, Panama, with concentrations ranging from 6 to 169 particles per gram of dry tissue and an average of 107 particles per liter in surrounding seawater.
Microplastics (≤ 10 μm) bioaccumulation in marine sponges along the Moroccan Mediterranean coast: Insights into species-specific distribution and potential bioindication
Researchers found that marine sponges along the Moroccan Mediterranean coast bioaccumulate small microplastics (10 micrometers or less), with species-specific differences in accumulation patterns, suggesting certain sponge species could serve as bioindicators for microplastic pollution monitoring.
Interaction Mechanisms Between Marine Sponges (Porifera) and Microplastics: A Bioecological Overview
This systematic review looks at how marine sponges — natural filter feeders — accidentally take in microplastics along with their food. The research shows sponges can accumulate significant amounts of tiny plastic particles, which may affect their health and the broader reef ecosystem. Since sponges play an important role in ocean nutrient cycling, their contamination with microplastics signals wider pollution concerns for marine food webs.
Microplastic distribution in urban vs pristine mangroves: Using marine sponges as bioindicators of environmental pollution
Researchers collected marine sponges from urban and pristine mangrove environments and measured microplastic content, finding significantly higher MP loads in urban sponges and demonstrating that sessile benthic sponges can serve as effective bioindicators of coastal microplastic pollution.
Measuring the Effects of Microplastics on Sponges
Researchers investigated how microplastics affect marine sponges, which are important filter feeders in coastal ecosystems, noting that very little research had examined sponge-microplastic interactions. The study aimed to fill a knowledge gap about microplastic impacts on a key group of benthic organisms that filter large volumes of seawater.
Interaction Mechanisms Between Marine Sponges (Porifera) and Microplastics: A Bioecological Overview
This systematic review summarizes how marine sponges, which are natural filter feeders, interact with microplastic particles in the ocean. The research shows that sponges unintentionally take in microplastics along with their food, which can cause cellular stress and may affect their ability to filter ocean water, with broader consequences for marine ecosystem health.
Fate of microplastic captured in the marine demosponge Halichondria panicea
Researchers tracked the fate of 2 and 10 micrometer plastic beads in the marine sponge Halichondria panicea, comparing their retention with that of edible bacteria and algal cells, finding that sponges retained plastic particles differently from food particles. The study advances understanding of sponges as microplastic monitoring organisms by revealing how plastic particles are processed within sponge tissues.

Sponges as Sentinels of Coastal Water Quality and Microplastic Contamination in Mallorca, Western Mediterranean
Researchers used marine sponges as bioindicators to assess coastal water quality and microplastic contamination in the Mediterranean Sea. Sponge tissues accumulated MPs reflecting local pollution levels, and the authors proposed standardized protocols for using sponges as long-term sentinel organisms for plastic monitoring.
Marine sponges as bioindicators of pollution by synthetic microfibers in Antarctica
Marine sponges from Antarctica's Tethys Bay were analyzed for synthetic microfiber contamination using a chemical depolymerization technique, finding evidence of polyester and polyamide plastics including PBAT/PPTA fibers and nylon 6,6 in multiple species. Even in this remote polar environment, sponges concentrated microplastics from large volumes of filtered seawater, suggesting they can serve as sensitive early-warning bioindicators for microplastic pollution. The detection of plastic pollution in Antarctica underscores how truly global the microplastic contamination problem has become.
Characterization of microplastics in the waters of the Santos Basin and the Ilha Grande Bay, and in marine sponges of the species Dragmacidon reticulatum (Ridley & Dendy, 1886)
This study characterized microplastics in coastal waters of two Brazilian bays and in the marine sponge Dragmacidon reticulatum. Microplastics were found in both water samples and sponge tissue, demonstrating that filter-feeding invertebrates accumulate plastic particles from their surroundings.
Sponge-Associated Amphipod Communities as Bioindicators for Pollution
This thesis examined whether amphipods living within sponges can serve as bioindicators of coastal pollution, including from microplastics. The research assessed how pollution affects amphipod community structure, diversity, and population dynamics in marine environments where sponge habitats are present.
Characteristic and histological evidence of microplastic in scleractinian corals of Java Sea
Microplastics were detected in seawater, sediments, and scleractinian coral colonies in the Java Sea, with histological evidence confirming MP uptake by coral tissue, raising concerns about microplastic impacts on reef health in this heavily impacted region.
Sponges as libraries: Increase in microplastics in Cinachyrella alloclada after 36 years
Researchers compared microplastic concentrations in the tropical sponge Cinachyrella alloclada using museum specimens from 1981 versus field-collected specimens from 2017, finding a tenfold increase from 0.13 to 1.37 microplastics per gram of tissue and an increase in prevalence from 10% to 80% of individuals, with Raman spectroscopy identifying polypropylene fibers as the dominant polymer type.
Could spatial variation be more important than species identity in determining the presence of microplastics in temperate sponges?
A study of microplastic contamination in temperate sponges found that the sampling location was a stronger predictor of microplastic presence than the sponge species, suggesting that local environmental conditions drive exposure more than species biology.
Microplastics in marine sponges (Porifera) along a highly urbanized estuarine gradient in Santos, Brazil
Researchers assessed microplastic contamination in marine sponges along an urbanization gradient in the Santos Estuary, Brazil. They found a 14-fold difference in microplastic concentrations between the most and least contaminated sites, with contamination patterns following the same gradient seen in molluscs from the same area. The findings suggest that marine sponges could serve as useful sentinel organisms for monitoring microplastic pollution in coastal environments.
Abundance of microplastic in sediment around the west coast of Situbondo, East Java

Microplastic filtering and its physiological effects on the Mediterranean bath sponge Spongia officinalis (Porifera, Demospongiae)
Researchers tested how the Mediterranean bath sponge filters and responds to microplastic particles in seawater. They found that these sponges are highly efficient at capturing microplastics in the 1-5 micrometer size range but showed signs of physiological stress including changes in respiration and cellular damage. The findings suggest that filter-feeding marine organisms like sponges are both exposed to and affected by microplastic contamination.
