Corals have algae called zooxanthellae living inside their cells, and giving them energy through photosynthesis. Some coral is developing a resistance to rising temperatures and even acidification. Reefs are actually inert physical structures created by living animals called corals, which in turn obtain most of their energy through a symbiotic relationship with microscopic algae. Reducing pollution and fish harvests on reefs is a reliable, low-risk solution for governments to consider. I don’t think we know.”. Coral reefs can come in contact with oil in three major ways: Oil floating on the water’s surface can be deposited directly on corals in an intertidal zone when the water level drops at low tide.
