These photos were taken by one of my friends who had an underwater camera. I just thought I'd share them as my whale shark-watching experience was mainly onboard our banca.
The photo below is a that of a whale shark coming head-on to my friend. When I was in the water, a similar scene was my scariest moment as when an incoming whale shark opened its mouth, I thought it would suck me in.
A little trivia before I end this post: Did you know that whale sharks (Rhincodon typus) are by far the largest living non-mammalian vertebrate, rivaling many of the largest dinosaurs in weight?
