Hammerhead sharks are some of the most improbable looking beasts in the sea. Dr. Michelle McComb, a researcher at the Shark Lab of Florida Atlantic University in Boca Raton, has been studying how these strange beasts see. The fact that their eyes are out at the ends of their oddly shaped heads was thought to be a problem for their vision. This, Dr. McComb has discovered, is not the case. In fact, the several species of hammerheads have remarkable binocular vision, and their widely-spaced eyes give them excellent depth perception. In addition, they also have an extremely wide field of view – up to 360 degrees. What this means is that hammerheds are well equipped to see their prey – and their predators.
