Males of the species Portunus sanguinolentus display a behavioral response to the presence of premolt females which is the same as their behavior when they are exposed to water in which premolt females have been kept. Release of a sex-attractant pheromone is indicated. When females are prevented from releasing urine, there is no evidence of the attractant.
