Around 30,000 sea birds have died after a tanker got smashed up in a terrible storm, leaking thousands of gallons of harmful oil into the water.
Hundreds of soldiers and volunteers have been brought in to help with clearing up the oil, in a desperate effort to stop more marine life dying.
Sunday's storm, in the Kerch Strait off the coast of Russia, wrecked five ships and several sailors drowned.
Officials have warned that the area is facing an "environmental catastrophe".
A Russian government spokesman said: "We're clearing up the shore and the water and we're pumping oil from a tanker damaged in the storm."
The Kerch Strait, between Russia and Ukraine, is a waterway separating the Black Sea from the Sea of Azov, which is rich with wildlife.
