Pandalus jordani is a protandrus (sequential) hermaphrodite. Populations show large year-to-year variation in age composition. In response to this variation, individuals alter the age at which they change sex. This response is predicted by a genetic model that assumes an individual shrimp maximizes its genetic contribution to the next generation.
