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

Reeds tolerant of salt water flourish in the shallow string of lakes extending from Suez north to the Mediterranean Sea. Kenneth Kitchen and James Hoffmeier state that these reedy lakes and marshes along the isthmus of Suez are acceptable locations for "yam suf". The ancient "yam suf" is not confined to the modern Red Sea. Hoffmeier equates "yam suf" with
