Lessepsian Migration

The Suez Canal, across which marine species migrate in the so-called Lessepsian migration
The Lessepsian migration is the migration of marine species across the Suez Canal, usually from the Red Sea to the Mediterranean Sea and, more rarely, in the opposite direction. When the canal was completed in 1869, fish, crustaceans, mollusks, and other marine animals and plants were exposed to an artificial passage between the two naturally separate bodies of water, and cross-contamination was made possible between formerly isolated ecosystems. The phenomenon is still occurring today. It is named after Ferdinand de Lesseps, the France diplomat in charge of the canal's construction.
