More studies of keystone species are needed, they added especially in the vulnerable larval stage. Think before you speak. These urchins developed normally, suggesting that abnormalities observed in other samples were caused by industrial additives and/or environmentally adsorbed contaminants -- rather than the base plastics themselves. Low pH had adverse effects on growth and morphology of sea urchin post-larvae. Also, too much sediment or other particles floating ScienceDaily, 30 November 2020.

"This study provides evidence that contamination of the marine environment with plastic could have direct implications for the development of larvae, with potential impacts on wider ecosystems. In nearly eradicating sea otters, humans had disrupted a critical trophic cascade: high sea otter numbers that mean low sea urchin populations that mean healthy kelp forests. Sea urchins and humans interact in a number of ways. Ocean acidification could interfere with the urchins ability to transform calcium, magnesium and other minerals from seawater into their tests (the white shell left when the animal dies), spines and teeth.
