We had another chance encounter with a whale shark earlier in the week. This one was an ~18' Female that just swam right over the top of me while I was on span 2. I stayed beside her long enough to snap a few photos before I decided the limited vis was probably not conducive to following her off into the Gulf for much longer. Niether of the other 3 divers I was with saw her at all. I am happy I happened to look up when I did!
