A coral reef is a critical underwater ecosystem made up of the hard skeletons of an invertebrate called coral. Though they support approximately 25% of ocean species, they account for less than 1% of the ocean’s area. In addition to being breathtakingly beautiful, coral reef ecosystems are critical to the survival of fish and other animals, including humans.

  • Coral reef ecosystems account for 0.1% of the ocean’s area.
  • Why are coral reefs important? They sustain 25% of ocean life.
  • They are hundreds of species that make up these unique ecosystems, including hard and soft coral.
  • The largest reefs, including the Great Barrier Reef, are found in tropical and subtropical waters, especially in the Caribbean and Australia.
  • How old are they? Today’s reefs have been around for between 6,000 and 8,000 years, according to the Reef and Rainforest Research Center (CRC).
  • There are four types: atolls, patch, barrier, and fringing, which take different shapes.

The Best Coral Reef Locations For Diving

There is nothing like scuba diving through one of the world’s most beautiful landscapes. No matter where you go, it’s critical to be a licensed diver and follow local instructions to preserve marine life. Here are the world’s most amazing diving locations.

Red Sea Coral Reefs

There is an incredible array of underwater life in the Red Sea, which is typically divided into the North Red Sea and the South Red Sea. Here are a few notable diving locations if you’re looking to explore a coral reef ecosystem, though there are great wrecks in the Red Sea, too:

  1. Ras Mohammed National Park, Egypt
  2. Sha’b Abu Nuhas Reef off Shadwan Island, Egypt
  3. The Blue Hole in Dahab, Egypt

Ras Mohammed National Park Coral Reef

Located at the far south of the Sinai Peninsula, this park contains fringing coral reef examples and over 220 coral species. Yolanda Reef and Shark Reef are known as good locations for divers to view the park’s renowned soft coral reef species. The Ras Mohammed National Park is also known for the SS Thistlegorm wreck, which sunk in 1941.

Sha’b Abu Nuhas Reef off Shadwan Island, Egypt

Located in the North Red Sea off Shadwan Island, the Sh’ab Abu Nuhas coral reef is best known for creating a dangerous shipping channel. This has led to a multitude of shipwrecks, making it a popular spot for divers.

The Blue Hole in Dahab, Egypt

Egypt’s most famous diving spot, the Blue Hole is a sinkhole with a depth of over 328 feet. Popular among technical divers and free divers, the Blue Hole is infamous for being the world’s most dangerous dive site, perhaps due to how challenging it can be to dive there.

6 Coral Triangle Diving Locations

Encompassing the Solomon Islands, Malaysia, Indonesia, Papa New Guinea, and Timor-Leste, the Coral Triangle is famous for its biodiversity.

Raja Ampat Island Coral Reef

This famous archipelago contains five main islands and may have the most marine diversity of any place in the world. This is due to Raja Ampat’s location between the Pacific and Indian oceans. It has survived due in part to its remote location and inaccessibility to tourists.

Coral Reefs in Kimbe Bay, Papa New Guinea

Sitting between two tectonic plates, the Kimbe Bay regio is home to a variety of volcanoes as well as underwater mountains covered in coral reefs. It is known for being relatively untouched because it is so remote, though scientist worry about the effects of coral bleaching on all reefs, including this one.

The Solomon Islands

The Solomon Islands, located in the aptly-named Coral Triangle, is another amazing example of marine biodiversity. Diving includes wide-angle coral reefs, and soft and hard coral alike. Popular diving locations include the Devils’ Highway, Florida Islands, Munda, and Barracuda Point.

The world’s most famous marine ecosystem, the Great Barrier is the largest coral reef in the world. It is over 1,400 miles long and 133,000 square smiles. Located off Queensland, Australia, the Great Barrier Reef is so large that you can see it from outer space.

Two-thirds of the Great Barrier Reef have suffered bleaching, according to scientists. This is the result of warmer water and changes in light and nutrients.

Two million people visit the Great Barrier Reef every year. The most popular diving locations along the Great Barrier include The Whitsundays and Cairns, though there are a variety of boating tours available. Osprey Reef is another great diving location in the area.

4 Types of Coral Reefs

Though each coral reef is unique in its biodiversity, there are structurally four main types:

  • Barrier
  • Platform
  • Fringing
  • Patch
  • Atoll

Here’s how to distinguish between them out in the wild.

What Is a Barrier Reef?

A lagoon or channel separates a barrier reef from land. The main difference between barrier and fringing is that that the former is separated by deeper water and its outer edge abuts open water rather than shore.

Famous Examples

  • Great Barrier Reef
  • New Caledonian Barrier Reef
  • Belize Barrier Reef

What Is a Fringing Reef?

Sometimes referred to as a shore reef, a fringing reef is in close proximity to the shoreline, either connected to it or separated by shallow water. Fringing reefs are very common and range widely in length, They typically exist just below the water, making them more accessible than other coral reef examples.

Fringing Reef Examples

  • Ningaloo Reef
  • Ras Mohammed National Park
  • Moloka’i
  • Weld Island
  • Gulf of Carpentaria

What Is a Platform Reef?

Also known as a patch reef, a platform reef typically grows on a continental shelf. Those that grow on sandbanks are typically long, whereas some are horseshoe shaped due to asymmetric currents.

Platform Coral Reef Examples

  • Torres Straight
  • Low Islets, which are part of the Great Barrier Reef

What Is an Atoll Reef?

These ring-shaped coral reefs can also take the shape of an island or series of islands. There is a lagoon at the center of an atoll reef. Sometimes they form around an extinct volcano. An atoll reef sits just below sea level.
