ClearAssessing the presence of microplastics in fiddler crabs (Afruca tangeri) and sediments of the salt marshes of Cadiz Bay (Spain).
This study assessed microplastic presence in fiddler crabs and sediments from coastal environments, where plastic accumulation can disrupt the fauna that depends on these habitats. Microplastics were found in both the crabs and surrounding sediments, indicating contamination throughout the coastal food web.
Fiddler crabs (Tubuca arcuata) as bioindicators of microplastic pollution in mangrove sediments
Researchers used fiddler crabs as bioindicators of microplastic pollution in mangrove sediments, finding that crab tissue microplastic loads correlated with sediment contamination levels and reflected spatial differences in pollution across mangrove sites.
Impact of mangrove restoration on microplastic bioaccumulation in fiddler crabs across degraded, restored, and natural ecosystems
Researchers compared microplastic accumulation in fiddler crabs across degraded, restored, and natural mangrove ecosystems in the Southern Gulf of Mexico. They found that mangrove restoration influenced the amount and types of microplastics that accumulated in the crabs and surrounding sediment. The study suggests that restoring mangrove habitats may help reduce microplastic exposure for the organisms living within them.
The Ecological Implication of Microplastic in Crabs from a Tropical Lagoon: Ingested Microplastic in Mud Crab Scylla serrata
Researchers examined microplastic ingestion by crabs from a tropical lagoon in West Africa, quantifying particles found in digestive tissues and assessing ecological implications for the local ecosystem. Widespread microplastic ingestion was documented across crab species and size classes.
Can fiddler crab bioturbation activity in situ modify the distribution of microplastics in sediments and the influence on their bioaccumulation?
Researchers examined fiddler crab (Minuca rapax) bioturbation in mangrove sediments of the southern Gulf of Mexico, finding that crab burrowing activity concentrated microplastics in burrow sediments and that the characteristics of microplastics ingested by the crabs reflected those found in burrows, with the degree of bioturbation-driven MP concentration varying with local urbanization levels.
Ecosystem engineers come to town: how fiddler crabs thriving in heavily polluted urban mangroves process plastic particles
Researchers tracked the uptake and fate of labeled polyethylene microspheres in the fiddler crab Minuca vocator in heavily polluted urban mangroves over 66 days, finding one of the highest microplastic ingestion rates ever recorded in nature (48.7 particles per crab) and examining how these ecosystem engineers process plastic-laden sediments.
A comparative analysis of microplastic contamination in hermit crab Clibanarius rhabdodactylus Forest, 1953, inhabiting intertidal and subtidal Coastal habitat of Gujarat state
Researchers compared microplastic contamination in hermit crabs inhabiting intertidal versus subtidal zones in Gujarat, India, finding higher microplastic loads in intertidal crabs due to greater exposure to coastal plastic pollution sources.
Microplastics in seafood as an emerging threat to marine environment: A case study in Goa, west coast of India
Researchers assessed microplastic contamination in water, sediment, and shellfish from the Sal estuary in Goa, India. They found microplastics present across all environmental samples, with sediment containing particularly high concentrations. The study highlights that commercially important seafood species in this region are accumulating microplastics, posing potential concerns for both marine ecosystems and human dietary exposure.
Effect of salinity on microplastic accumulation and osmoregulatory toxicity in the fiddler crab Minuca rapax
Researchers studied how water salinity affects the accumulation and toxicity of polyethylene microplastics in fiddler crabs from mangrove environments. They found that microplastics accumulated most heavily in the gills, and that salinity levels influenced both how much plastic the crabs absorbed and how it affected their ability to regulate body fluids. The study reveals that environmental salt conditions play an important role in determining how harmful microplastics are to estuarine organisms.
Microplastics are ubiquitous on California beaches and enter the coastal food web through consumption by Pacific mole crabs
Researchers assessed microplastic prevalence in beach sediments and Pacific mole crabs (Emerita analoga) along over 900 km of the California coast, finding microplastics in sediments at all 51 beaches sampled and in crabs at all 38 beaches where crabs were collected. On average, 35% of crabs had ingested microplastics, demonstrating that microplastics are entering the coastal food web through invertebrate infauna.
Ecosystem engineers come to town: how fiddler crabs thriving in heavily polluted urban mangroves process plastic particles
Researchers tracked the uptake and fate of labelled polyethylene microspheres released into plastic-polluted urban mangroves inhabited by the fiddler crab Minuca vocator over 66 days, recording one of the highest microplastic uptake levels ever observed in a wild organism at 48.7 particles per crab. The findings reveal how ecosystem engineers like fiddler crabs can bioturbate and redistribute microplastics through sediment reworking, with implications for both crab health and sediment-level microplastic dynamics.
Assessing microplastic accumulation in the hepatopancreas of marine and freshwater crabs from the North-East Part of the Bay of Bengal
Researchers compared microplastic contamination in the hepatopancreas of three edible crab species from the Bay of Bengal region, including two marine species and one freshwater species. They found that the freshwater crab had the highest microplastic counts, averaging nearly four particles per sample, and identified nine different polymer types across all species. The findings raise concerns about human exposure to microplastics through seafood consumption in the region.
Microplastic pollution in the surface waters, sediments, and wild crabs of mangrove ecosystems of East Java, Indonesia
Researchers surveyed microplastic contamination across ten mangrove ecosystems in East Java, Indonesia, finding microplastics in surface water, sediment, and wild crabs — with each crab containing an average of 48 plastic particles in its gills and digestive tract, more than 60% of which were fibers. The strong correlation between sediment contamination and microplastics found inside the crabs points to a pathway through which plastics enter the marine food web.
First Assessment of Plasticizers in Marine Coastal Litter-Feeder Fauna in the Mediterranean Sea
Five small-sized Mediterranean amphipod crustacean species from coastal litter-feeder habitats were analyzed for plasticizer contamination, finding detectable levels and identifying these litter-feeding invertebrates as potential monitors of microplastic-associated chemical pollution.
Microplastic contamination in Corpus Christi Bay blue crabs,Callinectes sapidus
Researchers assessed microplastic contamination in blue crabs (Callinectes sapidus) from Corpus Christi Bay, Texas, finding microplastics in crab stomachs and identifying fragment and fiber morphologies associated with sediment ingestion during benthic foraging. The study documents microplastic exposure in a commercially and ecologically important estuarine crustacean in the Gulf of Mexico.
Microplastics in Scylla Serrata: A baseline study from southwest India
Researchers examined microplastic contamination in the mud crab Scylla serrata from mangrove habitats on India's southwestern coast and found an average of about 29 microplastic particles per individual. Fibers were the dominant type, and polypropylene and polyethylene were the most common polymers detected. The study establishes a baseline for microplastic presence in a commercially important crab species, raising questions about potential human exposure through seafood consumption.
Warming-induced microplastic accumulation and physiological toxicity in fiddler crabs
Researchers studied the combined effects of microplastic exposure and rising water temperatures on fiddler crabs. They found that microplastics accumulated most heavily in the gills, and that warmer temperatures altered how the crabs responded to the plastic particles, increasing oxygen consumption and affecting antioxidant defenses. The study highlights how climate change and plastic pollution together may create compounding stress for coastal marine organisms.
Can the bioturbation activity of the fiddler crab Minuca rapax modify the distribution of microplastics in sediments?
Researchers investigated whether the bioturbation activity of the fiddler crab Minuca rapax can modify the distribution of microplastics in sediments along an urbanization gradient in the Gulf of Mexico. The study compared microplastic concentrations between burrows, feeding pellets, and crab tissues, finding that microplastics were more abundant and diverse in burrows. Evidence indicates that fiddler crab burrowing and feeding behaviors actively redistribute microplastics within coastal sediments.
Can the Atlantic ghost crab be a potential biomonitor of microplastic pollution of sandy beaches sediment?
Researchers tested the Atlantic ghost crab as a biomonitor for beach microplastic pollution, finding that the types of microplastics in crab gut contents closely mirrored those in beach sediment — confirming sediment as the main ingestion source — but that the crab's broad diet made it an unreliable indicator of overall contamination levels across beaches with different urbanization.
Microplastics occurrence in gills and digestive tract tissues of blue crabs collected from the Persian Gulf coast
Researchers documented microplastics in the gills and digestive tracts of blue crabs from coastal waters, finding MP particles of diverse types and sizes in both tissues and assessing implications for human health from consuming these commercially important crustaceans.
Trophic level transfer of microplastic: Mytilus edulis (L.) to Carcinus maenas (L.)
Researchers fed mussels pre-loaded with fluorescent polystyrene microspheres to crabs and detected the particles in haemolymph, hepatopancreas, ovary, and gills — demonstrating for the first time that microplastics can transfer naturally across a trophic level and translocate into the circulatory system of a predator.
The effects of trophic transfer and environmental factors on microplastic uptake by plaice, Pleuronectes plastessa, and spider crab, Maja squinado
Researchers examined microplastic uptake in plaice and spider crab from the Celtic Sea alongside their prey (sand eels), finding plastic contamination in roughly 42–50% of all three species and documenting the first confirmed trophic transfer of microplastics from prey to predator in a wild marine food chain, though proximity to land rather than fishing intensity predicted exposure levels.
Beyond Abiotic Decay: Fiddler Crabs Accelerate Plastic Fragmentation in Pollution Hotspots
Researchers found that fiddler crabs mechanically accelerate plastic fragmentation in mangrove forests — recognized plastic sequestration hotspots — through their burrowing and feeding activities. The study demonstrates that these ecosystem engineer crabs, which thrive in plastic-pollution hotspots, actively contribute to microplastic generation, potentially amplifying plastic contamination in coastal sediments.
Microplastics uptake and accumulation in the digestive system of the mud crab Rhithropanopeus harrisii
Lab experiments with Harris mud crabs showed the crabs readily ingested microplastics, which accumulated in their digestive systems. While plastic exposure did not significantly affect crab growth during the experiment, the findings confirm that crustaceans in brackish estuaries can ingest and retain microplastics.
