This is a very grouchy Cowtail Stingray that I photographed in the Great Barrier Reef. They are quite large with meaty, thick bodies. They can reach nearly 6 feet wide, but this one had a 4 to 4.5 foot span. There were quite a few in the area where I took this photograph; you can see several in the background. I think they are really neat, but I had to be a bit careful getting too close because they would raise their tails and point their serrated spine forward at me. They are very cool animals, but not something that you want to accidently step on. When wading through the water, you feel like you are in a bit of a prehistoric minefield.
