I was watching a show on sea snakes last night and this particular sea snake being of terrestrial origin can't lay it's eggs in water. So it lays them in this underwater cave. The neat thing about the cave was that a fog or cloud was generated when the waves created high and then low pressure variations. It reminded me of this plastic bottle demonstration.

There were better shots of the mist effect in the actual show.

Around the 3:47 mark it looks like a brief clockwise circular motion is occurring instead of the typical jam jar torus, and at the neck,
the outflow flame segregating to the right.
