Coral reefs are a vulnerable underwater ecosystem that is the most diverse in the world. These reefs forms along the edges of continents or islands when the coral larvae of aquatic inhabitants attach to hard surfaces such as submerged rocks.  usatales

With time the coral grows in size and becomes home to thousands of coral polyps (the animals that help build the reefs). These coral colonies create the structure of the reefs.

Coral reefs are formed due to years and years of coexistence among fish, algae, and invertebrates. Most coral reefs are built by marine animals that create a hard skeleton, known as stony corals, and grow best in warm, clear, shallow, and agitated water.

Coral reefs are home to about 25-35% of marine life, including worms, fish, mollusks, sponges, crustaceans, tunicates, sea urchins, and other fish species. And that is why it is considered one of the best aquatic ecosystems and is also known as the rainforests of the sea.

Over 15,000 species of coral reef fishes can be found or identified, and many of them are commercially important fish species. Some of the most common reef fish found in coral reefs include the snapper, red bass, clownfish, butterflyfish, several species of coral trout, small crustaceans, and many other species.

The coral reef habitat consists of coral reef fish mostly known for their characteristic features, such as being sharp and having bonny rays and spines.

Even many marine tropical fish can be found close to coral reefs.
