Red Sea

The Red Sea is a seawater inlet of the Indian Ocean, lying between Africa and Asia.The connection to the ocean is in the south through the Bab el Mandeb strait and the Gulf of Aden. In the north, there is the Sinai Peninsula, the Gulf of Aqaba, and the Gulf of Suez leading to the Suez Canal .

The Name 
Red Sea is a direct translation of the Greek Erythra Thalassa . Arabic Al-Baḥr Al-Aḥmar or Baḥr Al-Qalzam.The name of the sea may signify the seasonal blooms of the red-coloured Trichodesmium erythraeum[ is a type of filamentous cyanobacteria] near the water's surface.
Another hypothesis is that the name comes from the Himyarite, a local group whose own name means red.
It is theorized that it was named so because it borders the Egyptian Desert, which the ancient Egyptians called the Dashret or "red land"; therefore it would have been the sea of the red land.The mountains surrounding the red sea [ Red Sea Mountains]is high and reddish in color.
The Red Sea is one of four seas named in English with color terms [ the Black Sea, the White Sea and the Yellow Sea].

In the photo you can see the red color of the stones of the mountains of the red sea .  

Its History 
The earliest known exploration of the Red Sea was conducted by Ancient Egyptians, as they attempted to establish commercial routes to Punt [type of boats]. One such expedition took place around 2500 BC, and another around 1500 BC. Both involved long voyages down the Red Sea. 
Along the history there were many attempts to connect The Red Sea with The White Sea ,that ends with The Suez Canal ,that  was opened in November 1869.

Its Geology
The Red Sea was formed by Arabia[ Arabian Peninsula] splitting from Africa due to movement of the Red Sea Rift. The sea is still widening and it is considered that the sea will become an ocean in time.
The Red Sea is a rich and diverse ecosystem [ An ecosystem is a biological environment consisting of all the organisms living in a particular area, as well as all the nonliving, physical components of the environment with which the organisms interact, such as air, soil, water, and sunlight].More than 1200 species of fish have been recorded in the Red Sea, and around 10% of these are found nowhere else. This also includes 42 species of deepwater fish .

The Tourism
The sea is known for its spectacular  sport diving sites, such as Ras Mohammed ,and Rocky Island in Egypt and less known sites in Sudan such as Sanganeb, Abington, Angarosh and Shaab Rumi .Popular tourist resorts include El Gouna, Hurghada, Safaga, Marsa Alam, on the western shore of the Red Sea, and Sharm-El-Sheikh, Dahab, and Taba on the Egyptian side of Sinaï, as well as Aqaba in Jordan and Eilat in Israel in an area known as the Red Sea Riviera.
Tourism in the South of the Red Sea is presently considered risky because of the presence of pirates originating from uncontrolled zones of Somalia. Large vessels such as cargoes are sometimes attacked by heavily armed high-speed boats. The situation is even worse in the Gulf of Aden between Somalia and Yemen.

I had never dive under the red sea but I had tried to imagine what is there and I designed that picture .
I designed it with photo-shop ,using the Custom Shape Tool ,and Free Transform to adjust the size[ scale] direction .
