This 20 August 2014 video is about a lifeboat, tugging a drifting dead whale from the sea near Katwijk in the Netherlands to the beach near Scheveningen.
There, scientists of Naturalis museum investigated it today. It turned out to be a seventeen meter long adolescent male fin whale.
Most probably, the young whale died because of a collision with a ship; some of its vertebrae were crushed. Other possible causes of death: a killer whale attack; or a collision with a seawall.
