The survival risk posed by microplastics is also exacerbated by degrading coral reefs, as dying corals make particularly younger fish more desperate to find nutrition and shelter, and to venture into waters where they are more likely to be taken by predators themselves. In a joint study conducted by Australia’s James Cook University as well as other institutions including the University of Cambridge, marine ecologists pulse fed groups of juvenile ambon damselfish, housed across several tanks, a diet of brine shrimp.
