ClearCharacteristics of Microplastic in Selected Marine Sponges from Pasir Putih Situbondo, East Java, Indonesia
Microplastics were characterized in marine sponges collected from a specific ocean region, finding plastic particles of diverse polymer types embedded in sponge tissue. Marine sponges, as filter feeders, accumulate microplastics from surrounding water and may serve as useful bioindicators of ocean plastic contamination.
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.
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 organisms that filter large volumes of seawater.

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.
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.
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.
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.
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.
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.
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.
Preliminary 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.
Could spatial variation be more important than species identity in determining the presence of microplastics in temperate sponges?
Researchers found microplastics present in every sponge sample across six species and three sites in Wellington Harbour, New Zealand, and determined that spatial location explained 40–53% of the variation in microplastic abundance compared to only 4–24% explained by species identity, highlighting site-level pollution as the dominant driver.
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.
