At 37C, the sea urchin eggs reached the first cell cleavage at 40 minutes after fertilization, and cleaved the second time at 65 minutes after fertilization. The plastic-to-water ratio in the study would only be seen in severely polluted places, but the findings raise questions about the wider impact of plastic contaminants on marine life. Because kelp attaches to the seafloor and eventually grows to the waters surface and relies on sunlight to generate food and energy, kelp forests are always coastal and require shallow, relatively clear water.
