There are many more danger's coral faces or other words what harm's coral reef's. They also face many threats like coral bleaching and maybe us humans also.
The most common way for coral to die is from water changing temperature. They can also die in danger of coral bleaching. (Go to coral bleaching tab to learn more) People polute the water and may come to coral reefs. Coral reefs can also die from climate change and extremely low tides pollution which can harm coral really badly.
Other threats to coral reef'´s are humans. Humans can damage coral by hunting them with tools that can hurt them. Coral can also catch diseases like living animals.
70-90% of Coral maybe dissapear in the next 20-50 years.
Coral faces danger mostly by climate change. If it gets too hot it will probably die or disappear.
Irritating toxin is discharged into the skin from small structures on the coral — the mechanism is similar to jellyfish stings. In most cases, the burning sensation starts immediately after contact and increases for the first 10 minutes or so.
overfishing sediment, nutrient and marine pollution; and increasing ocean warming and acidification. Is another danger coral faces and Overfishing is the most pervasive local threat to coral reefs.
Species of Zoanthid corals like Palythoa and Zoanthus species can contain a highly toxic and potentially lethal chemical compound known as palytoxin.
If to much pollution gets to any coral or coral reefs, they will dissaper and there maybe no more coral reefs.
Some Zoanthid coral species popular with marine aquarium enthusiasts can contain Palytoxin. This toxin is dangerous to your health and being exposed to it can have potentially life-threatening consequences.
The most danger coral faces is between climate change or pollution. Now, lets start with pollution. Pollution can damage a lot of things like fishes and other sea animals, But pollution for coral is dangerous obviously but if coral disappears, 25% of marine life would disappear! And we do not want that. (continued on your right side.) --->
The initial responses of coral injuries including stinging pain, erythema, and swelling occur immediately to within several hours around the wound4. These symptoms result from coral poisoning.
Now, for climate change, climate change for coral is bad just like

Zoanthid coral CAN contain palytoxin
Species of Zoanthid corals like Palythoa and Zoanthus species can contain a highly toxic and potentially lethal chemical compound known as palytoxin. They can be found as polyps, attached by a fleshy stolon that can be created from small pieces of sediment zoanthid coral is mostly a soft coral but still contains palytoxin. Little sea spiders can decimate a colony pretty quickly.
60% of coral reefs have already been lost due to human-related activities, also 80% of southeast Asia reefs are endagered. Witch means that we need to stop pollution and take care of our coral! By 2030, about 90% of coral reefs are expected to be endangered. Overfishing can unbalance coral ecosystems by encouraging excessive growth of coral predators. Coral's enemies/predators are fish, marine worms, barnacles, crabs, snails and sea stars. The biggest threat to corals are sharks. Sharks are known as the "apex predator of coral reef's". Tiger sharks are also one of the biggest threats to coral reefs or coral in general.
