Experiments with robots explain synchronized courtship in fiddler crabs

Male fiddler crabs (Uca mjoebergi) produce highly synchronized courtship waves. Is this a cooperative behaviour because females preferentially approach groups that wave synchronously? Or is it a competitive behaviour because of female choice for males that wave first, with the resultant selection on males generating synchrony as an epiphenomenon [1]? To find an answer we used robotic male crabs to measure female mating preferences. We show that females do not prefer males waving in synchrony,...[Show more]
