I am sure if I hadn&amp;#x27;t played it cool. Had somehow attacked or acted aggressively to shush it away (when I was a guest in it&amp;#x27;s deep sea domain). It would have enjoyed a nice lunch of fresh human flesh.&lt;p&gt;The second was going below the hard deck at 300 feet whilst diving the continental shelf in the Caribbean. It&amp;#x27;s stunning. Floating weightlessly over the void that drops suddenly over a mile in depth. Feeling the rush of frigid current rise from the abyss. And seeing mysterious shapes as light filters down into darkness.

Touch anything and you get scratched (which I did). Your cables or tank can easily get caught (which it briefly did for me - and since I was the last one in the group it was quite scary seeing the group getting away from me as I tried to catch up).

I ended up using more air than I suppose was normal, and there would not have been enough to make a normal ascent. I ended up having to use the dive instructor&amp;#x27;s alt supply for some of the return swim and switch to my own for the safety stop, otherwise I would&amp;#x27;ve run out.
