Cover: A male fiddler crab Uca vomeris showcasing its large claw and magnificent eyes, kept high above the substrate by the long eye stalks. Photograph by Jochen Zeil. The graph below shows how a fiddler crab (red circles) responds to a dummy (blue circles) approaching its burrow (see the papers by Hemmi and Zeil, pp. 3935-3950 and 3951-3961). The crab's velocity (cm s-1) is shown as a continuous line at the bottom; negative velocity values indicate that the crab moved towards the burrow (time periods where the crabs responded to the dummy are identified by black circles below).
