This was an incredible day. We were on a pretty normal dive on Pelican Shoal when a school of millions of bait fish swam through us. We soon saw that they were being pursued by barracuda, grouper, jacks and sharks. This went on for an hour. The school covered 1/8 to ¼ acre and made the sea black when they swam over us.This was an incredible day.
