With the opening of the Volga-Don canal in 1952 navigation between the oceans and the Caspian became possible. Contact between the previously secluded Caspian marine ecosystem and the outside world was consequently inevitable. The connection led to the introduction of various alien species (plants and animals not native to the habitat). The most threatening event for the Caspian ecosystem was the arrival of the North American comb jelly (Mnemiopsis leidyi).
