There are many theories as to why sharks do this, and here are some of my favourites:
1) Is it because they are tired, and the extra rush of water pumping more oxygen in?
2) Is it a show of strength/threat?
3) Is it a sign of frustration?
4) Is it a way for sharks to help clean their teeth?
All of the above are recorded theories, but which one is your favourite??
