From a trip to Tiger Beach a couple weeks ago, I had two Giant Hammerheads near the edge of the abyss. They were about 12-13' long and incredibly fast and agile. Watching them cut through the water was like watching massive living razor blades. I am standing while filming this and the top of the dorsal fin was at chest height while it scraped its pectoral fins along the bottom.
