marine food chain. In shallow water these toxic substances may directly kill algae‚ coral and sea grasses. These components may also be passed in the food chain or directly ingested or absorbed through the gills of fish and other larger marine organisms. The effect may be to kill the animal or contaminate its tissues. A thick film of oil on the sea surface may reduce sunlight penetration and reduce photosynthesis. Small particles and emulsions may be ingested or block the feeding mechanisms of invertebrates
