The Suez Canal, which connects the Red Sea to the Mediterranean Sea, revolutionized maritime travel by creating a direct shipping route between the East and the West. But as Egypt marks the 150th anniversary of its opening, marine biologists are bemoaning one of the famed waterway's lesser known legacies, the invasion of hundreds of non-native species that have driven the native marine life toward extinction and altered the delicate Mediterranean ecosystem with potentially devastating consequences.
