Fishes have commonly evolved reproductive pheromones with diverse physiological (“primer”) and behavioral (“releaser”) effects on conspecifics; only recently has it become clear that many reproductive pheromones of fishes might be comprised solely or partially of hormones and related compounds from hormone synthesis pathways. Over their long period of evolution, guppies have developed distinct color patterns and methods to populate new areas.
