[VIDEO] - Humpback whale spotted off the Belgian coast
01/10/11 - A humpback whale has been spotted off the Belgian coast. It is assumed that the images were recorded close to the Thornton area, some 25 kilometres off the Belgian mainland. It's probably a young whale. Adults can grow to a length of 15 metres and a weight of 30 tons. Humpbacks live across the world, but it's very rare to spot them in the North Sea.
