Yang et al. investigate the genetic basis of pheromone-elicited fright behavior in ostariophysan fish. They identify a subfamily of vomeronasal type 2 receptor-like (OlfC) that appears to be under strong positive selection; its transcriptional variation suggests a role in the fright behavior of ostariophysan fish.
