Response of barnacle nauplii to microplastic exposure and algal size: survival, grazing and behavior
AI summary Read the abstract
Scientists studied how baby barnacles (tiny sea creatures) react when they encounter microplastic particles while trying to eat algae, and found that contact with plastic bits caused the larvae to switch from feeding mode to swimming away. This matters because it shows microplastics can disrupt feeding behavior at the very bottom of the ocean food chain—and since these tiny creatures are eaten by fish that eventually end up on our plates, disruptions here could ripple upward through the food web we depend on.
We examined survival, algal consumption, and behavioral responses of barnacle Semibalanus balanoides nauplii exposed to different algal species and microplastics. This dataset contains five videos corresponding to Table 1 in the manuscript, "Response of Barnacle Nauplii to Microplastic Exposure and Algal Size: Survival, Grazing, and Behavior". These recordings document naupliar responses to microplastic exposure and were used to quantify behavioral transitions from feeding to swimming mode following particle contact.

Response of barnacle nauplii to microplastic exposure and algal size: survival, grazing and behavior
AI summary Read the abstract
Scientists studied how baby barnacles (tiny sea creatures) react when they encounter microplastic particles floating in water alongside their normal food (algae). They found that contact with microplastics caused the barnacles to switch from feeding mode to swimming away, suggesting these particles disrupt normal eating behavior in small marine organisms. Since these barnacles are part of the ocean food chain, this matters because it hints at how microplastic pollution could affect the health of marine ecosystems—and ultimately the seafood many of us eat.
Fate of Nanoplastics in Marine Larvae: A Case Study Using Barnacles, Amphibalanus amphitrite
AI summary Read the abstract
Researchers tracked the fate of nanoplastics in barnacle larvae, finding that these tiny particles were ingested and could accumulate in larval tissues, with potential implications for early development and survival of marine invertebrates.
Non-selective feeding on microplastics in the acorn barnacle Amphibalanus amphitrite: the implications in assessing barnacles as global microplastics bioindicators
AI summary Read the abstract
Researchers studied microplastic ingestion by striped barnacles (Amphibalanus amphitrite) by exposing them to three plastic types, two sizes, and two concentrations, with and without biofilm coatings. Barnacles ingested microplastics non-selectively regardless of type or biofilm status, confirming them as useful bioindicators of plastic pollution in marine environments.
The Behavior of Planktonic Copepods Minimizes the Entry of Microplastics in Marine Food Webs
AI summary Read the abstract
Researchers found that planktonic copepods across all major feeding behaviors ingested microplastics at rates up to ten times lower than similar-sized microalgae, suggesting that copepod feeding strategies naturally limit the entry of microplastics into marine food webs.
Species-specific microplastic ingestion responses to biofilm in Eastern Tropical Pacific zooplankton
AI summary Read the abstract
Scientists studying tiny ocean creatures (zooplankton) found that whether these organisms eat microplastic particles depends on both the species and whether the plastic has a coating of algae and bacteria (called biofilm) on it — one species preferred coated plastic, another preferred bare plastic, and a third didn't care either way. Since zooplankton are at the base of the ocean food chain, this matters because it shows microplastic pollution can enter marine food webs in unpredictable ways, which is relevant to understanding how plastics may eventually work their way up to the seafood humans eat.
