[Coral-List] More on interesting interactions between divers and reefs

[Osmar Luiz Jr]

The mechanic action of he bubbles isn't the only problem..  remember that 
the sessile invertebrates attached on the top of the cave or the ceiling of 
a wreck are gone be out of water when bubbles becames trapped on the top...

All the best
