Lanternfish as bioindicator of microplastics in the deep sea: A spatiotemporal analysis using museum specimens
AI summary Read the abstract
Researchers analyzed lanternfish specimens collected across space and time from the deep sea to assess their utility as bioindicators of microplastic pollution, examining spatiotemporal patterns in microplastic occurrence and abundance in these mesopelagic fish.

Lanternfish as bioindicator of microplastics in the deep sea: A spatiotemporal analysis using museum specimens
AI summary Read the abstract
Using archived museum specimens of lanternfish collected from 1999 to 2017, researchers tracked microplastic ingestion trends in one of the world's most abundant deep-sea vertebrates. They found that 55% of 1,167 specimens contained microplastics, with ingestion probability increasing over time, and that migration patterns were the strongest predictor of contamination levels.
Influencing factors for microplastic intake in abundant deep-sea lanternfishes (Myctophidae)
AI summary Read the abstract
Researchers found microplastics in 68% of mesopelagic lanternfish from the Southwestern Tropical Atlantic, with body size and feeding depth identified as key factors influencing microplastic intake in these abundant deep-sea fish.
Influencing factors for microplastic intake in deep-sea lanternfishes
AI summary Read the abstract
Deep-sea lanternfish in the Southwest Atlantic were found to ingest microplastics, with feeding behavior, body size, and habitat depth all influencing how much plastic each fish consumed. Lanternfish are among the most abundant fish on Earth and play a critical role in transporting carbon and contaminants from surface waters to the deep ocean. Microplastic contamination in these fish could have far-reaching effects on deep-sea food webs and carbon cycling.
The complex issue of chemicals and microplastic pollution: A case study in North Pacific lanternfish
AI summary Read the abstract
Lanternfish (a common deep-sea fish) were examined for microplastics and associated chemicals, finding that chemical exposure from their natural prey was far greater than from microplastics. This suggests that while microplastics are present, they may not be the primary route of chemical contamination in deep-sea fish.
First Report of Plastic Fragments in the Lanternfishes Collected from the Sea of Oman
AI summary Read the abstract
Researchers documented for the first time that lanternfish — deep-sea fish that migrate vertically each day — collected from the Sea of Oman had ingested plastic fragments. Because lanternfish are abundant and widely eaten by larger predators, their plastic ingestion could serve as a pathway for microplastics to move deeper into marine food webs and eventually into seafood consumed by humans.
