No its a plant.
Umm... the above answer is not true. Coral Reef is a biome = =
Oh yes and if you were talking about the stuff that grow in coral reefs, they are made of many coral polyps which are very tiny animals.
Petoskey is actually fossilized coral.
Coral Castle is made of coral rock. Coral rock is a type of limestone. Coral Castle was constructed by one man working alone over a period of twenty-eight years.
igneous
Coral Rock was created in 1973.
Over time coral reefs may be changed into a firm sedimentary rock, known as reef rock, and eventually into a dense, solid limestone. An example is the Coral Rag Formation around Oxford England. Some Coral Rag was used as a building stone. It can be seen in some of the oldest buildings in that city.
Limestone and chalk.
It grows on the sea beds, but that kinda is a rock. If a coral polyp lands on a rock, I guess coral can grow there! =)
The rarest type of coral is the Elkhorn coral.

Yes, a Petoskey stone is a type of sedimentary rock. It is formed from the remains of ancient coral reefs found in freshwater deposits in Michigan, USA. The stone is composed of fossilized coral, which gives it its distinct pattern.
