Dead animal on the surface of the water: Fishermen make an impressive discovery at sea. At first glance you might think it's an inflated ball.

However, it is actually the carcass of a humpback whale. The photos were taken off the Norwegian island of Andoya in the Vesteralen region, near the fishing village of Bleik. The whale is fully grown, the fisherman emphasizes. It could be up to 15 meters long and weigh 30 to 40 tons. After death, the body expands due to the gases.
