Best Answer

A stony coral colony begins as a single free-swimming founder coral polyp that attaches itself to a hard substrate such as submerged rocks.

The founder polyp replicates itself repeatedly through asexual reproduction, producing a colony. The colony consists of a base which is attached to the reef substrate, a growing edge zone (where new coral polyps are produced), and an upper surface that is exposed to light that filters down through the water.

A Substance, as harder as stone, that is formed by the skeletons of tiny sea animals is called Corals.

The tiny sea animals like sea anemone secrete calcium carbonate from their outer layer which protects them from other substances. As calcium carbonate when exposed to air becomes harder and stronger thus forming a hard outer skeleton. These skeletons remain for ever even after the organism inside it die or another organism grow in it.

These skeletons are called Corals. Corals are of a variety of types. Some corals appear to be coloured due to the chemicals present in it.

Some large communities of corals even form small islands.

Reefs form when free-swimming coral larvae attach to something in the sea, like rocks or other hard surfaces on the edge of landforms. Reef islands form when these larvae attach to rocks or hard things floating freely out at sea.

A volcanic island or underwater mountain forms via volcanic activity. This allows a surface near the water surface for corals to attach too. The corals form a ring around the volcano.

How can coral atoll be attached to ocean floor when coral cannot live or form reefs in the deep ocean?

Coral atoll are tiny sea animals that live in shallow water, but when reefs form the new coral grow over the skeleton of the old. As the ocean crust beneath the volcano sinks, the coral sinks with it, and the new coral continues to form on top of the old. Eventually, coral covers the whole volcano. It can survive with the ocean waves bringing in new food and more marine life.


What form coral reefs?

Coral polyps create the large hard structures known as coral reefs. The coral grows due to the build up of calcium carbonate that the corals secret.
