All guts, no glory: ingested microplastics in marine mammals

Summary

This brief review summarized findings on microplastic ingestion by marine mammals, noting that microplastics have been found in a wide range of marine habitats and are consumed by animals from the base of the food chain to large top predators. Marine mammals serve as important sentinels for tracking microplastic contamination through marine ecosystems.

Microplastics (pieces less than 5 mm in size) have now been discovered in a wide range of aquatic habitats, from deep-sea sediments to seemingly pristine tropical beaches. Their small size and omnipresence mean that microplastics can be eaten by animals at the base of the food chain as well as larger animals. - submission by Sarah Nelms
