Description:
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).
