The Red Sea:
Red Sea is a direct translation of the Greek Erythra Thalassa (Ερυθρὰ Θάλασσα) and Latin Mare Rubrum (alternatively Sinus Arabicus, literally "Arabian Gulf"), Arabic Al-Baḥr Al-Aḥmar (البحر الأحمر) or Baḥr Al-Qalzam(بحر القلزم), Somali Badda Cas and Tigrinya Qeyyiḥ bāḥrī (ቀይሕ ባሕሪ).
The name of the sea may signify the seasonal blooms of the red-coloured Trichodesmium erythraeum near the water's surface. The Red Sea (alternatively Arabian Gulf or Gulf of Arabia) 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 Red Sea is a Global 200 ecoregion. The sea is underlain by the Red Sea Rift which is part of the Great Rift Valley.
The Red Sea has a surface area of roughly 438,000 km² (169,100 mi²). It is about 2250 km (1398 mi) long and, at its widest point, 355 km (220.6 mi) wide. It has a maximum depth of 2211 m (7254 ft) in the central median trench, and an average depth of 490 m (1,608 ft). However, there are also extensive shallow shelves, noted for their marine life and corals. The sea is the habitat of over 1,000 invertebrate species, and 200 soft and hard corals. It is the world's northernmost tropical sea.
