Description: Tiff was nervous about diving 100 feet in a submarine, but she enjoyed the spacious interior and large portholes. We saw a white reef shark, green sea turtles, numerous bluefin trevally, and many other interesting fish that were not their usual colorful selves due to color absorption in deep water.
