Size: Plastics larger than 20mm. Examples: Fishing gear, six-pack rings, plastic bottles. Threats: Large items of plastic can capture and entangle marine mammals and fish and stop them from escaping, usually leading to starvation, injury and predator vulnerability. Discarded fishing nets can also smother and break coral reefs, preventing ...
Jun 26, 2023 · Marine mammals, of course, don’t understand the dangers plastics pose to them. This problem was created by humans, and only humans can fix it. Every year in Australia 130,000 tonnes of plastic leaks into our oceans, and this goes on to indiscriminately kill marine mammals, birds and other creatures.
In this chapter we dive into the different forms of plastic documented in the marine environment, the reported effects of plastic on marine mammals as a model for numerous other aquatic species and the marine environment and how the One Health approach to human and animal health helps us better understand and assess past, current and future impacts on both individual- and population-level health.
Jan 15, 2021 · Reviews on plastic ingestion and entanglement by marine mammals (e.g. Baulch and Perry, 2014; Simmonds, 2012) have highlighted the abundance of interactions of marine mammals with plastic debris. Given the growing interest in this field, the objective of this study was to conduct the first systematic literature review on microplastics and marine mammals.

Feb 1, 2021 · An illustration showing pathways for bioaccumulation of microplastics (MPs) in marine mammalian food webs, indicating the feeding preferences and foraging strategies in marine mammals (e.g., fish-eating killer whales, pinnipeds, filter-feeding humpback and bottom-feeding grey whales) and potential microplastic exposure via prey (zooplankton/krill, benthic crustaceans and fish).
