Pandalus jordani is a protandrous (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 that an individual shrimp maximizes its genetic contribution to the next generation.
日本囊对虾是一种雌雄同体（顺序）的动物。种群的年龄组成在年际间存在较大变化。个体根据这种变化改变其性别的年龄。这种反应是由一个遗传模型预测的，该模型假设个体虾最大限度地增加其对下一代的遗传贡献。
