Sperm whales are said to dive down to more than 1000 meter, after taking a 
breath at the surface. When they take a breath at the surface the pressure 
of the air is 1 bar. Approximately the same as the pressure of the 
surrounding water. However at 1000 meter depth the pressure of the 
surrouding water is 100 bar. How do they cope with this tremendous 
difference in pressure without breaking any ribs ?
