Wow! Just watched this yesterday on Netflix and while I've seen mention of this film discussed on this forum I'm putting it back out there for those, whom like myself, did not know about this movie. Great reef cinematography, interviews with the great J.E.N. Veron, coral reef biology and the pearls that effect the areas we are so interested in.
