Dataset of impact of micro and nanoplastic in early juveniles of Limulus polyphemus of the Yucatán Peninsula
Original title: Dataset of impact of micro and nanoplastic in early juveniles of Limulus polyphemus of the Yucatán Peninsula
AI summary Read the abstract
Scientists tested how tiny plastic particles (microplastics and even smaller nanoplastics) affect baby horseshoe crabs, tracking their survival, growth, breathing, behavior, and internal stress responses over three weeks. Horseshoe crabs are ecologically important and their blood is even used to test the safety of vaccines and medical devices, so understanding how plastic pollution harms them can reveal broader risks to ocean food chains that eventually connect back to human health. This dataset provides the raw numbers behind those findings for other researchers to study further.
This is the numerical data from the study investigating the impact of 21 day exposure to 3 diferent treatment; microplastics, nanoplastics and control over the survival, growth, muscle water content, oxygen consumption, behaviour and antioxidant system on the early-stage juveniles of Limulus polyphemus on the Yucatán Peninsula.

Dataset of impact of micro and nanoplastic in early juveniles of Limulus polyphemus of the Yucatán Peninsula
AI summary Read the abstract
Scientists exposed young horseshoe crabs to tiny plastic particles (microplastics and even smaller nanoplastics) for three weeks to see how it affected their survival, growth, breathing, behavior, and internal stress levels. This matters because horseshoe crabs are a key part of ocean food chains, and understanding how plastic pollution harms marine life early in life can help us predict broader risks—including how plastics moving up the food chain might eventually affect the seafood we eat.
Emerging microplastic threats to horseshoe crabs: accumulation patterns and toxicity mechanisms
AI summary Read the abstract
This review pulls together existing research showing that horseshoe crabs, ancient sea creatures whose blue blood is actually used to test the safety of vaccines and medical devices, are accumulating tiny plastic particles in their bodies and eggs, sometimes alongside toxic metals and antibiotics. These pollutants appear to harm the crabs' growth, behavior, and gut health, which matters because horseshoe crabs sit at the base of a coastal food chain and play a unique role in medical safety testing, meaning their decline could ripple out to both ecosystems and human health systems in ways we don't fully understand yet.
Particle size influences physiological responses to chronic exposure to polyethylene particles in juvenile Atlantic horseshoe crabs (Limulus polyphemus).

Baby horseshoe crabs exposed to tiny plastic particles for three weeks grew slower, especially when exposed to larger microplastic fragments, even though other health markers looked normal. This suggests microplastics can subtly stunt growth in young marine animals, a reminder that plastic pollution's impact on marine food chains, and potentially the seafood we eat, deserves continued attention.
Differential effects of pristine and aged polystyrene nanoplastics on the first molting process in Tachypleus tridentatus
AI summary Read the abstract
Scientists found that tiny plastic particles (nanoplastics) harm baby horseshoe crabs by disrupting their ability to molt, or shed their shells to grow, a critical step for survival. Surprisingly, "weathered" plastic particles (the kind that break down from sunlight exposure in real oceans) caused this harm through different, less-understood mechanisms than fresh plastic particles typically used in lab studies. This matters because most plastic pollution in the environment is aged, not fresh, meaning current safety testing may be underestimating real-world risks to marine life, and potentially to the seafood humans eat.
Effects of Pristine and UV-Aged Polystyrene Nanoplastics on Post-Molt Horseshoe Crabs Tachypleus tridentatus: Aging-Mediated Divergence in Biological Effects.
AI summary Read the abstract
Scientists found that tiny plastic particles (nanoplastics) affect young horseshoe crabs differently depending on whether the plastic has been broken down by sunlight, surprisingly, "fresh" plastic caused more stress to the crabs' bodies than sun-damaged plastic. This matters because horseshoe crabs are vital to coastal ecosystems and medical testing (their blood is used to check vaccine safety), and it shows that how plastics age in the environment changes their potential harm, a factor scientists need to consider when studying how microplastics might affect other species, including humans, through the food chain.
