Compared to land animals, it's relatively difficult to study the behavior of underwater creatures in great detail. To gain a greater understanding of how great white sharks navigate kelp forests off the coast of South Africa as they track down Cape fur seals, scientists lured sharks to a research boat. They then strapped cameras with motion sensors to eight of the predators.
