Fiddlers on the roof: elevation muddles mate choice in fiddler crabs
Biological signaling usually occurs in complex environments, yet signals are most often studied in controlled experiments that strip away this complexity. Male fiddler crabs possess one enlarged claw that is waved during courtship displays, and females preferentially respond to larger claws and faster waves. Fiddler crab vision is evolutionarily specialized to their predominantly level mudflat habitats, although some populations inhabit topographically complex environments. Here, we...[Show more]
