What exactly is coral?

Corals are marine invertebrates within the class Anthozoa of the phylum Cnidaria. They typically live in compact colonies of many identical individual polyps. Coral species include the important reef builders that inhabit tropical oceans and secrete calcium carbonate to form a hard skeleton.

What makes up a coral reef?

A coral reef is made of thin layers of calcium carbonate

Coral polyps form a living mat over a calcium carbonate skeleton. ... Massive reef structures are formed when each individual stony coral organism—or polyp—secretes a skeleton of calcium carbonate.

What are the 4 types of coral reefs?

Scientists generally divide coral reefs into four classes: fringing reefs, barrier reefs, atolls, and patch reefs. Fringing reefs grow near the coastline around islands and continents. They are separated from the shore by narrow, shallow lagoons. Fringing reefs are the most common type of reef that we see.

What are examples of coral reefs?

The Northwest Hawaiian Island coral reefs, which are part of the Papahānaumokuākea National Marine Monument, provide an example of the diversity of life associated with shallow-water reef ecosystems. This area supports more than 7,000 species of fishes, invertebrates, plants, sea turtles, birds, and marine mammals.

In addition to weather, corals are vulnerable to predation. Fish, marine worms, barnacles, crabs, snails and sea stars all prey on the soft inner tissues of coral polyps. In extreme cases, entire reefs can be devastated if predator populations become too high.

What are the three types of coral?

The three main types of coral reefs are fringing, barrier, and atoll.

Does coral need sun?

Sunlight: Corals need to grow in shallow water where sunlight can reach them. Corals depend on the zooxanthellae (algae) that grow inside of them for oxygen and other things, and since these algae needs sunlight to survive, corals also need sunlight to survive.

Do corals have brains?

The cerebral-looking organisms known as brain corals do not have brains, but they can grow six feet tall and live for up to 900 years!
