In Reply to: What is a stone shark? posted by que on Friday, 2. December 2011 at 06:49 Bali Time:
A stone shark is actually coral reef. There is a place in west java where a coral reef near a lovely beach is in the shape of a shark. It is a bit of a tourist attraction.
Any surfer having surfed over coral knows how sharp it can be and how easily just grazing the skin can cuse instant cuts and abrazions.
