What type of coral is reef building?
Stony corals (or scleractinians) are the corals primarily responsible for laying the foundations of, and building up, reef structures.
Is coral classified as rock?
Corals are animals like ourselves, although that they may not be readily apparent because many look like rocks, especially those washed up on the beach. In a sense, corals are indeed partly rock, because only the outer thin layer of the coral is inhabited by the coral animal itself.
Where are reef building corals found?
tropical and subtropical waters
The majority of reef building corals are found within tropical and subtropical waters. These typically occur between 30o north and 30o south latitudes.
How is a coral reef formed?
Coral reefs begin to form when free-swimming coral larvae attach to submerged rocks or other hard surfaces along the edges of islands or continents. As the corals grow and expand, reefs take on one of three major characteristic structures — fringing, barrier or atoll.
What is coral classified?
Classification: Though a coral polyp looks like a plant, it’s really an animal, or rather, a colony of animals, and is classified into the Phylum Cnidaria (also called Phylum Coelenterata). Corals are an ancient group having a simple, radially-symmetrical body with a single opening that serves as both a mouth and anus.
What two physical factors determine where reef building corals grow?
Figure 8-1.
- Light: Corals need a moderate amount of sunlight in order to survive.
- Depth: Reef building corals must live where there are moderate amounts of light.
- Water temperature: Remember that corals thrive in the warm waters of the tropics.
- Salinity: Salinity is usually measured in parts per thousand (ppt).
What are the three types of coral reefs?
The three main types of coral reefs are fringing, barrier, and atoll. Schools of colorful pennantfish, pyramid, and milletseed butterflyfish live on an atoll reef in the Northwestern Hawaiian Islands. The most common type of reef is the fringing reef. This type of reef grows seaward directly from the shore.
