We are in a plastic pandemic. Despite efforts to curb plastic production, an estimated 4.8 to 12.7 million metric tonnes of plastic continue to enter marine environments each year (1). One primary source of marine plastic and debris is abandoned, lost, or discarded fishing gear. An estimated 2% of all fishing gear is lost to marine environments annually (2), impacting marine environments and inhabiting species. Bioplastics have emerged as a promising alternative to fossil-based plastics; however, work to quantify their ecological impact in marine environments is in its infancy. To assess the potential ecological impact of bioplastics, we examine the ingestion of bioplastic fishing lures by marine invertebrates in intertidal habitats along the Australian east coast. We reveal that marine invertebrates are more likely to consume bioplastic fishing lures than those made from fossil-based plastics. These findings highlight the need to understand better the interactions between marine invertebrates and different types of plastics. Future research will address the critical gaps in the impacts of plastic exposure and ingestion on marine invertebrates' health, fitness and microbiome, providing valuable insights into the degradation of plastics in marine environments and their ecological implications.
