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.
well it is formed with a object called marine organisms from the class anthoza
Coral islands are formed by water going through sandy soil when it goes at the bottom the coral island is formed.
your mom is a coral reef
Coral are small animals that build colonies in warm tropical waters. The coral reef is the ecoskelton of the animal. Black coral is just one color of coral ecoskelton.
Coral is the hard rock-like substance that is formed by skeletons of tiny sea animals. These calcareous skeletons build up and form islands and reefs.
Coral reefs are built by millions of coral polyps, small colonial animals resembling overturned jellyfish. They excrete an exoskeleton made of calcium carbonate, which forms their distinctive shapes as a colony. Thousands of coral colonies build up over time to form the reef. After an extensive period of time, the reef may die off, perhaps because the conditions of the environment change for the worse for the corals. Since reefs often form in conditions where there is a lot of water movement (because the water is more oxygenated in these areas), if the colony is no longer being sustained by living polyps the colonies break up. Reefs can still break up when the coral is still alive if the conditions are severe. Sedimentation and cementation occurs as calcium carbonate precipitates out of the water and of the exoskeletons of the coral.

Fire coral is a red coral that gives you deep cuts and stings you that can last over 3 weeks!Stay away!!!
No. The coral reef is formed by polyps.
called hermatypic coral.
Coral reefs come from living organisms and they form colonies of all sizes and shapes.
no
A coral polyp is an individual coral cell, and when polyps stick together, they form coral a.k.a. Coral Polyp Colonies. Later, when the polyps die, their skeleton (which is like a hard shell) Strengthens the coral formation.
Coral makes up coral reefs. Coral by definition are microscopic animals with an outer skeleton of calcium carbonate that form colonies and are responsible for reef building.
its a form
Coral reefs begin to form when free-swimming coral larvae attach to submerged rocks. Both natural conditions and those created by man is what make coral reefs vulnerable to environmental stress.
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.
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.
