Did you know that the biggest shark that has ever existed was the megalodon?

Did you know that sharks don’t stop swimming, not even for when they need to sleep?
This is because of wo reasons. The first is because of their breathing. Whilst sharks swim, they maintain their mouth open, this way the water that contains a lot of oxygen, passes through their gills and absorbs the oxygen to be able to breath. The second reason is that, differently from all fish, sharks don’t have a swim bladder a kind of internal float that fills with air and allows them to float even though they are still. It sounds weird but it is true, if a shark stops swimming it will fall to the bottom of the ocean and drown. Although the sleeping fish is eaten by the shark…..

One of the most iconic visual elements of the Second World War are German panzers blitzing their way across enemy territory, leaving a trail of death and destruction in their wake.
During the First World War, German tanks had a less than auspicious start. Their first attempt at a tank design was the A7V, a clunky metal box on tracks, a far cry from the formidable vehicles of a quarter century later.
