The beauty of coral reefs

Some of the underwater ingredients are fascinating

The underwater world has an interesting and beautiful feel that is in the environment of the coral reef, which is used as a place for occupying fish and other animals.

Coral reefs in marine habitats on the sea floor are colonies of tiny animals found in marine waters that contain little nutrients. Most coral reefs are constructed of rocky rock, which in turn consists of polyps that are grouped in groups. polyps belong to a group of animals known as cnidarians, which also include sea anemones and jellyfish.
