I have a question, let's assume that the person shooting the video is snorkling... Let's say that person is within earshot of the other person and *can* shout too them that there is a shark below....
Don't you think that would cause MORE panic by screaming "SHARK" (scene from Jaw's plays out in my head), the snorkler's all start splashing around making a big scene...
I mean in this particular situation, what could you really do BUT to watch (and of course render aid afterword if a bite does occur)??
This raises some interesting questions for me acutally, questions like:
If your diving and see this, do you bolt for the surface to warn people (thus risking DCS, but possibly saving a life)? Do you take some other sort of action (I doubt squirting a bit of air from your octo is going to scare that shark away, but who knows right)?
I think this thread could really turn into a great topic if we fully discuss the possibilities.
I think I'll go make some popcorn and wait for the regular posters and dive professionals to chine in here
