The effects of model polysiloxane and fouling-release coatings on embryonic development of a sea urchin (Arbacia punctulata) and a fish (Oryzias latipes)

► Fouling-release coatings caused developmental toxicity in sea urchins and fish. ► Fouling-release coatings, presumed nontoxic, may impact non-target organisms. ► The work warrants further study on environmental impacts of silicone coatings.
