yea, i wouldnt have worried to much about a reef shark, but a mako, or great white and im jumping out of the water lol.
the problem with corals is, theyre on their way out in the wild. they say another 10-20 years and the reefs will be gone. to me, thats a shame. heat is one of the factors, pollution another and believe it or not, carbon dioxide levels according to this article http://www.enn.com/top_stories/article/40175
i thought i had more links to support my claim, but its true.. and its happening. im sure a google search about corals dying in the wild would provide some hard facts.
and im looking forward to your next trip
