First record of microplastics in stomach content of the southern king crab Lithodes santolla (Anomura: Lithodidae), Nassau bay, Cape Horn, Chile
AI summary Read the abstract
This study reported the first detection of microplastics in the stomach contents of king crabs (Lithodes santolla) collected in Patagonia, finding plastics in about 27 percent of stomachs. The findings expand the known range of microplastic ingestion to commercially important crustaceans in sub-Antarctic waters.
This study reports the first record of microplastics in the stomach contents of the king crab Lithodes santolla. Samples were collected in Nassau Bay during September 2017. Plastics ingested belonged to small microplastics between 3.0 and more than 20 mm long having mainly blue color. Their frequency of occurrence in stomachs was 27%. The microplastic ingestion by L. santolla may present not only a risk for the species self, also for other trophic levels in the food web.

AI summary Read the abstract
Researchers investigated microplastic ingestion by four deep-sea decapod crustacean species in the Sardinian and Catalan regions of the Western Mediterranean, analyzing gastrointestinal tracts from 210 individuals to assess abundance, characterization, and species- and region-level differences, finding ingestion prevalence of approximately 70%.
Microplastic exposure and biological correlates in a key intertidal crab (Grapsus grapsus) from the Galápagos Islands
AI summary Read the abstract
Researchers quantified microplastics in the gills and gastrointestinal tracts of Sally Lightfoot crabs from the Galápagos Marine Reserve, finding particles in 78% of gill samples — higher loads and greater polymer diversity than gut tissue — and confirming that even this remote protected ecosystem is permeated by anthropogenic microdebris.
Presence of Microplastics in Cronius Ruber Species
AI summary Read the abstract
Researchers examined microplastic content in the stomach contents of Cronius ruber, an invasive crab species in Mediterranean waters, finding plastic particles — primarily fibers — in the animals. The presence of microplastics in invasive crab species adds to the evidence that plastic ingestion is widespread across marine crustaceans in contaminated coastal waters.

AI summary Read the abstract
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.
The Contamination of Microplastic Debris in Blue Swimming Crab Portunus pelagicus (Linnaeus, 1758) from Artisanal Fisheries in the Eastern Gulf of Thailand
AI summary Read the abstract
Researchers collected blue swimming crabs from the Gulf of Thailand and found microplastics in 62.5% of external body parts and 72.2% of internal parts, with fibers dominating and gut tissue showing the highest contamination. The findings indicate widespread MP ingestion in commercially harvested crabs and potential food safety implications.
