Last Wednesday I went on a spearfishing trip with the South Texas Freedivers to dive a floating oil platform. Not much success on the platform, so we moved to a permanent oil rig and ran into this big guy. I have been scuba diving for 25 years and freediving for about 10 years and never seen one of these whale sharks before. It was an amazing encounter. It kept coming back to the rig several times and didn't seem to mind the human interaction. It actually turned and steered towards me on one occasion.
