Suez Canal Opening in 1869 Led to 120 Fish Species Entering Mediterranean

The Suez Canal was opened in 1869, creating a new waterway connecting the Red Sea to the Mediterranean. Following its opening, approximately 120 fish species crossed from the Red Sea into the Mediterranean Sea through the canal. This biological migration represents one of the most significant human-caused species transfers in maritime history. The phenomenon, now known as Lessepsian migration, has had lasting ecological impacts on Mediterranean marine life.
