Hi, I was diving the Blue Hole in Belize when I saw this shark patroling. I apologize for the quality of the pictures. He was quite far away. I don't have a good point of reference for the size but we were down about 130 feet at the time. He seemed quite large and he made a circle around us but kept his distance. I think it might be a bull shark but I appreciate any input. This site has been invaluable in helping me to identify fishes I saw on my trip!
