There’s no travel destination on Earth like the Red Sea. A seawater inlet that is part of the Indian Ocean, this unique body of water between Africa and Asia with extensive shallow shelves is known for its extremely rich marine life and abundant reefs that are unlike others around the world for several reasons. Take a look at these interesting Red Sea coral reef facts to discover why!
13 Interesting Red Sea Coral Reef Facts
Red Sea Corals Are Extremely Heat-Resilient
Corals around the globe are in danger due to ocean warming and acidification. According to scientists, the coral reefs of the Red Sea appear to be more resilient against rising sea temperatures than most others.
The Red Sea ecosystem houses one of the longest continuously living reefs in the world. Scientists note that the hard coral species found in the northernmost portion of the sea that extends into the Gulf of Aqaba have an incredibly high tolerance for rapidly warming seawater that would normally cause severe coral bleaching.
The Red Sea Fringing Reef Can Become A Refuge For Marine Life
Portions of the Red Sea may be essential for the survival of marine life in the face of rising temperatures. The unique biological mechanisms that allow Red Sea corals to be resilient are currently being studied to see if the environment can be replicated. According to scientists, these “super corals” may create a model for restoration once climate-change stress is mitigated.
The conservation community is so optimistic about the Red Sea’s role that the Great Fringing Reef of the Red Sea in Egypt has been named a Hope Spot by Mission Blue.
Red Sea Corals Have High Salinity Tolerance
The Red Sea is one of the saltiest bodies of water in the world. A combination of high evaporation, heavy winds, and limited fresh-water inflow leaves the sea with 40% salinity. This salty environment is perfect for reef-building coral species; that’s why they can build massive structures like fringing reefs and barrier reefs.
Several Countries Work Together To Protect The Area’s Reefs
Sharing its sacred marine waters with Egypt, Jordan, Israel, Saudi Arabia, Yemen, Somalia, Sudan, Eritrea, and Djibouti, the Red Sea is one of the world’s most important bodies of water due to its geopolitical position and environmental value.
The above-mentioned countries are members of the PERSGA (Regional Organization for the Conservation of the Environment of the Red Sea and Gulf of Aden) and have teams that constantly monitor the health of the area’s coral reefs.
There Are More Than 300 Hard Coral Species In The Red Sea
One of the most interesting facts about the Red Sea is that it has roughly four times the coral diversity of the Caribbean! Its reefs present an incredible variety within a space that only covers 174,000 square miles.
Roughly 300 species of hard coral have been recorded in this sea. Nearly 200 of them are concentrated along the Egyptian coast.
These Reefs Are Thousands Of Years Old
Portions of reef peppering the Red Sea Coast date back to biblical times. Coral is the longest-living animal on Earth. However, the reefs in the Red Sea break records. While it’s not uncommon to find reefs around the world that are thousands of years old, these reefs date back to 5000-7000 years ago.
Certain Fish Species Only Live On The Red Sea’s Reefs
More than 1,000 different species of fish have been identified within this body of water. These colorful creatures rely on corals to raise their juveniles to adulthood.
If the corals of the Red Sea were to disappear, entire species would disappear. That’s because roughly 10% of the fish that call these enchanted waters home aren’t found anywhere else on the planet!
Coral Reefs Provide Shelter To Various Marine Animals
Creatures ranging from the smallest of plankton to massive sea mammals depend on Red Sea corals to fuel the circle of life. These waters are famous for their incredibly rich marine biodiversity.
Some of the showstoppers commonly spotted by divers and snorkelers include sea turtles, giant morays, blue-spotted ribbontail rays, eagle rays, and various dolphin species, but rare animals such as dugongs (sea cows), manta rays, whale sharks, and certain shark species can also be seen here.
Reefs Provide Food For Sea Turtles
Five of the world’s seven marine turtle species can be found in the Red Sea waters. Out of these five species of Red Sea turtles there is one, the critically endangered hawksbill sea turtle, that depends entirely on coral reefs for survival.
Easily distinguished due to their distinctive pattern of overlapping shell scales, these beauties feed on sea sponges growing on corals using their narrow beaks.
The Region Offers Top Conditions For Diving And Snorkeling
The Red Sea attracts millions of tourists yearly; snorkelers and divers from all over the world come to the region to witness its healthy and vibrant marine life. The coastline, especially the Coast of Egypt, features some of the earth’s most popular diving and snorkeling sites.
For instance, the northern region around Sharm El-Sheikh has protected national park reefs (Ras Mohammed National Park) offering opportunities for both beginner and expert underwater explorers. There are also many world-famous wrecks to dive including the famed SS Thistlegorm cargo steamship.
The southern region allows divers and snorkelers to encounter magnificent creatures such as huge sea turtles, sharks, manta rays, and the rare dugongs of Marsa Alam. Underwater wonders are guaranteed no matter what coastal area you travel to in Egypt!
The Red Sea Is Heaven For Underwater Photographers
Thanks to its ultra-clean waters and extremely diverse marine life, the Red Sea coral reefs provide some of the best conditions for underwater photography. With a variety of sea creatures living on them, from tiny nudibranchs to tube worms, miniature fish and big animals like whale sharks and manta rays, these waters have a lot to offer for both macro and wild-angle photographers!
It Is A Year-Round Travel Destination
The Red Sea is warm enough to enjoy water activities and explore its reefs year-round. The lowest water temperature is 70-72 degrees Fahrenheit (21.1-22.2 °C) throughout December and January.
During the summer, the water temperature averages 82-84 degrees Fahrenheit (27.8-28.8 °C). In addition, the region experiences year-round sunshine, making it an excellent vacation destination no matter the season.
Corals Need Our Help
While the Red Sea coral reefs are extremely resilient to climate change and environmental challenges, their protection should not be neglected. As part of conservation efforts, human activities that include hunting wildlife are prohibited in most coastal regions. In areas where water activities are practiced, mooring buoys have been placed to prevent damage from boat anchors.
Us tourists should aim to protect the natural environment, too; while snorkeling or diving, make sure not to harm the underwater world and keep the following in mind:
- Do not feed the fish, as it can upset the balance of the marine ecosystem
- Do not touch corals; standing or walking on them damages the fragile tissue of the reef-building organisms
- Do not remove shells, corals, rocks, plants, and soil for any purpose; taking corals out of the country is forbidden and results in a fine if caught at the airport with any piece of coral in the suitcase.
FAQs
Why is the Red Sea coral reef so important?
Thanks to the fact that its corals are extremely climate-tolerant, scientists think that the Great Fringing Reef of the Red Sea can survive rising temperatures, provide shelter for marine life, save species from extinction, and therefore can have a crucial role in repopulating the world’s other reefs.
What types of corals are in the Red Sea?
Around 300 hard and soft coral species can be found in the Red Sea. The two most common species are the Porites (Finger corals) and Acropora (staghorn, elkhorn, and table corals) stony corals.
Why is the Red Sea coral reef so special?
Corals in the Red Sea are unusually tolerant against extreme conditions such as heat, high water temperatures, and salinity. These unique features make the Red Sea corals likely to withstand climate and environmental challenges better than reefs in other parts of the world.
How healthy is the Red Sea coral reef?
Despite climate change-related challenges, the Red Sea reefs are considered generally healthy compared to others in the world. There are heavily damaged areas due to unregulated coastal development, but no mass bleaching has been reported so far.
