Similar to that of the Atlantic Ocean reefs, rubble reefs in the Gulf of Mexico face the same issues. One of the most common ailments to coral reefs is bleaching. Due to an increase or decrease in water temperature, the corals expel an algae, known as zooxanthellae, turning it completely white and making it very susceptible to diseases. Another environmentally based issue is ocean acidification, resulting from the increased absorption of carbon dioxide in the oceans. Many of the other problems are directly attributed to humans such as overfishing and collection of Panulirus argus (Florida Spiny Lobster) , Menippe mercenaria (Florida Stone Crab), Ocyurus chrysurus (Yellowtail Snapper), Lachnolaimus maximus (Hogfish), and many more. The near constant marine traffic leads to many cases of boats running aground and dropping their anchor on coral heads and divers touching corals and other organisms within the ecosystem. The biodiversity of ecosystems in the Gulf of Mexico also face the dangers associated with the negative impact of oil spills.
