The Red Sea also referred to as the Erythraean Sea is considered to be the saltiest sea of all the seas that connect to the ocean without even one river meeting the sea and is lying between Africa and Asia. The Red sea connects to the Indian ocean is in the south through the Bab el Mandeb strait and the Gulf of Aden while to the north is the Sinai Peninsula, the Gulf of Aqaba, and the Gulf of Suez (leading to the Suez Canal) and the Gulf of Aqaba are present towards the north side of the Red Sea. The Red Sea is among the 200 Global ecoregions. Therefore, this article will be providing you with Red Sea Facts including the sea’s location, history, oceanography, ecosystem, and all you need to know.

Here are the few things we will give answers to in this write-up

The Red Sea is among the four seas on earth whose name was coined after colours. The Red Sea surface area is estimated to be around 438,000 km2, its length is about 2250 km and, and has a width of 221 miles with 355 been the widest point. The Red Sea has a maximum depth of 3,040 m in the central Suakin Trough and measured an average depth of 490 m. the red sea also has extensive shallow shelves, which are known for their marine life and corals. The sea is the home to over 1,000 invertebrate species, including 200 soft and hard corals live in the sea. The Sea is regarded to be the northernmost tropical sea in the world.

  • How the Red Sea was created

The Red Sea came to be as a result of the Arabian peninsula being split from the Horn of Africa by movement of the Red Sea Rift. The split originated from the Eocene and fast-tracked during the Oligocene.

  • Countries Bordering the Red Sea

The red sea is bordered by a total of six countries border. These countries are mainly African countries and Asia countries reason been that, the Red Sea flows between the two continents. The Red Sea borders many countries; it borders Saudi Arabia, Yemen, Jordan, and Israel to the eastern side and borders Egypt, Eritrea, Sudan, and Djibouti to the western side.




  • How the Red Sea Got its Name

The Red Sea name originated from the Greek words “Erythra Thalassa”. The sea is named after the Red color because of the seasonal blossoms because of a type of algae called popularly called Trichodesmium erythraeum, which is found in the sea and appears near the surface of the water. The red color that is seen as a result of the death of the blooms of algae which turns the blue-green color of the sea to a reddish-brown.

  • Animals in the Red Sea

There are over 1,200 species of water life animals living in the Red Sea and 10% of them are rampant which are found in a particular place and nowhere else. Living in the Red Sea are sea animals such as the amazing Reefs with a teeming marine life, pelagic fishes, Reef Sharks, Dolphins, and even the rare Dugong. Also, about 1,240 miles or 2000 kilometres of coral reef is seen along the Red Sea shores on the eastern side. They are approximately 5000 to 7000 years old and are visited by some of the fishes. There are 44 shark species that visit the coral reefs of the Red Sea some of which are the bigeye houndshark, grey reef shark, star spotted smooth-hound, milk shark, snaggletooth shark, silvertip shark, whale shark, and zebra shark. Some of these sea animals especially the tiger shark, scorpionfish, rabbitfish, and stingrays poise a threat to people.

Also, the Red Sea is home to the world’s fastest fish, the solitary sailfish. The fish can swim at speeds of up to 68 miles per hour. What speed!

  • The salinity of the Sea

The red sea is highly salty water and the saltiest as such. The sea’s salinity in the south side is averagely around 4% – 3.6% and 4.1% in the north side. This salt level is higher than the world average 3.5% due to high evaporation but very less precipitation; also no rivers empty themselves in the Red Sea and less connection with the Indian Ocean. The Red Sea waters only exchanged with the Indian Ocean and the Arabian Sea through the Gulf of Aden which also contributes to its high salinity.

  • Desalination Plants

There are numerous desalination plants (at least 18), planted along the Red Sea coast of Saudi Arabia which releases warm brine and treatment chemicals (chlorine and anti-scalants) that bleach and kill corals and also cause diseases in the fish. This is only localized, but it may intensify with time and intensely influence and improve the fishing industry. This has helped meet the extensive demand for desalinated water by the population and the industries located along the Red Sea. Also, the water from the Red Sea is used by oil refineries and cement factories for cooling. The flow of used water back into the coastal zones may cause harm to the environments near the shore of the Red Sea.

  • Tidal Range of the Red Sea

The normal and general tide range is between 0.6m in the north, close to the bank of the Gulf of Suez and it is 0.9m in the south close to the Gulf of Aden but fluctuates between 0.20m and 0.30 m distal from the nodal point. The central Red Sea (referred to as the Jeddah area) is almost tideless, and as such the annual water level varies and very significant.

  • The current of the Red Sea

Presently, there is no detailed information about the Red Sea current, possibly because the currents are weak and vary both spatially and temporally. The Temporal and spatial currents variation is as low as 0.5 m and is overseen typically by the wind. In summer Northwest winds drive surface water southward for a period of four months at a velocity of 15-20 cm per sec., while in winter the flow of water is reversed leading to the inflow of water from the Gulf of Aden back into the Red Sea.

  • Red Sea Recreational Activities

The Red Sea is one of the best water to dive in the world and this has made it a major hot spot for “scuba diving” and swimming when you consider the rich variety of its underwater ecosystem. Nearly 20% of the 1,200 species of fishes, as well as the 44 shark species, are found only in the Red Sea. Divers can swim within the large body of water in the company of brightly colored angelfish, butterflyfish and clownfish. Diving conditions in the Red Sea are sublime and relaxing. The sea is known for its remarkable recreational diving sites such as the SS Thistlegorm (shipwreck), Ras Mohammed, Elphinstone Reef, The Brothers, Daedalus Reef, St.John’s Reef, Rocky Island in Egypt.

  • Red Sea Temperature

The Red sea’s temperature is moderate and the water temperatures rarely fall below 71°F/22°C even in the depths of the Egyptian winter. In the summer season, water temperatures in the southern section of the Red Sea typically reach 86°F/30°C – making it possible to plan multiple dives without getting ice-cold. Topside weather conditions are equally pleasant, with temperatures fluctuating between 68°F/20°C – 104°F/40°C depending on the time of year.

  • Mineral Resources

There are six (6) major mineral resource found in the Red sea includes:

  1. Biogenic constituents: foraminifera, Nanofossils, pteropods, and siliceous fossils.
  2. Volcanogenic constituents: cristobalite, montmorillonite, Tuffites, volcanic ash, and zeolites
  3. Terrigenous constituents: clay minerals, fragments, Quartz, rock feldsparsmica, and heavy minerals,
  4. Authigenic minerals: aragonite, chalcedony, Sulfide minerals, Mg-calcite, protodolomite, dolomite, and quartz.
  5. Evaporite minerals: anhydrite, gypsum, Magnesite, halite, and polyhalite
  6. Brine precipitate: anhydrite, Fe-montmorillonite, goethite, hematite, pyrite, rhodochrosite, sphalerite, and siderite.
