Often described as “living fossils” for their prehistoric physiology, horseshoe crabs are thought to rely on sight for only the most fundamental tasks — making them ideal for studying how visual stimuli affect behavior. Hence Barlow recorded what a dozen “Crabcam”-adorned specimens saw on a Massachusetts beach last spring and then replayed the footage to an audience of
Perhaps not startling news, but Barlow insists it’s a crucial first step in learning how the brain interprets such tantalizing imagery.
