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.

Is dead coral a rock or a mineral?
Dead coral is a rock because it is composed of the skeletal remains of marine organisms called coral polyps that have hardened over time. It is made up of the mineral calcite, which is a crystalline form of calcium carbonate.
How are coral and limestone formed?
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.
What animals eat brain coral?
Probably fish that live in the tropics because that's where brain coral lives and that is it because brain coral eats its own food
Which rock was formed from skeleton and shells of sea animals and plants?
Limestone is a rock that is formed from the skeletal remains of sea animals and plants. It is primarily composed of calcium carbonate, which is derived from the shells and skeletons of marine organisms such as coral, mollusks, and foraminifera. Over time, these remains accumulate and become compacted and cemented to form limestone rock.
What is fire coral?
Fire coral is a type of marine organism that resembles coral but is actually a type of hydrozoan. It has a stinging sensation when touched, causing a painful rash or irritation on the skin. It is important to avoid contact with fire coral while diving or snorkeling.
Do flatworms form coral reef?
No. The coral reef is formed by polyps.
Skeletons of living coral grow together to form a structure called a?
called hermatypic coral.
Why does coral come in different shapes?
Coral reefs come from living organisms and they form colonies of all sizes and shapes.
Do coral reefs form when the calcite skeletons of coral build upon each other.?
no
What is a coral poly?
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.
Is coral only found in coral reefs?
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.
Relationship between eel and a coral?
its a form
How do coral reefs form what makes them vulnerable to environmental stress?
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.
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.
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.
Is it true Coral reefs form when the calcite skeletons of coral build upon each other?
True .
What rocks form under water?
sedimentary
