Mediterranean Sea factors. The opening of the Suez Canal in 1869 created the first salt-water passage between the Mediterranean and Red Sea. The Red Sea is higher than the Eastern Mediterranean, so the canal serves as a tidal strait that pours Red Sea water into the Mediterranean. The Bitter Lakes, which are hyper-saline natural lakes that form part of the canal, blocked the migration of Red Sea species into the Mediterranean for many decades, but as the salinity of the lakes gradually equalised with that of the Red Sea, the barrier to migration was removed, and plants and animals from the Red
Mediterranean Sea or Islamic sources. It may be to contrast with the Black Sea. In Persian, the name was translated as "Baḥr-i Safīd", which was also used in later Ottoman Turkish. It is probably the origin of the colloquial Greek Άσπρη Θάλασσα. Johann Knobloch claims that in Classical Antiquity, cultures in the Levant used colours to refer to the cardinal points: black referred to the north (explaining the name Black Sea), yellow or blue to east, red to south (i.e., the Red Sea), and "white" to west. This would explain both the Turkish "Akdeniz" (White Sea) and the Arab nomenclature described above.
