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. Humpback whales have so-called bubbling tongue, which describes the underside of their mouth. After death, the body expands due to the bacteria and other gases, causing the body to bloat.
