That dead reef can come back to life when the climate changes to produce the proper conditions again to sustain coral growth. The physical coral heads will not become active again but new heads will be produced by new coral poylps on top of the old ones. A dead Coral is like any other animal when it's dead it's dead.

Does coral turn into rock?

Hard, or stony, corals make rocks that can, on geological time scales, lead to the formation of massive reefs in shallow tropical and subtropical seas.

Is coral a stone or a gem?

Precious coral belongs to a small, but important group of gemstones, which technically are not stones at all. Rather than being minerals with crystalline structures like most colored stones, coral is formed through a biological process and thus belongs to an elite class of organic gems.

How old is coral rock?

Corals can be either colonial or solitary. As fossils, corals are found worldwide in sedimentary rocks. Based on these fossils, we know that the corals began their long evolutionary history in the Middle Cambrian, more than 510 million years ago.

Does coral have eyes?

People often mistake corals for marine plants – or even rocks! This is because corals attach to the seafloor, can have hardened surfaces or features that make them look like terrestrial plants, and they don't have obvious features like eyes or mouths that would suggest that they are animals.

What kind of rock does coral turn into?

The type of rock that the coral skeletons build is called limestone. Limestone has been forming in Earth's oceans for more than 400 million years. Limestone deposits that began as coral reefs provide evidence of how Earth's surface and environment has changed.

Are coral rocks fossils?

Because modern corals live in large colonies, these skeletons can become quite large, sometimes forming reefs. When the polyp dies, its soft tissue decays, but the hard skeleton is left behind. The hard skeleton of ancient corals is what is preserved as a fossil.

Why is it illegal to harvest coral?

Removal of coral and “live rock” from reefs removes critical habitat for fish and other animals. Economic losses. Coral mining creates a significant long-term loss to society, including a loss in fisheries value, coastal protection, and tourism.
