小室鹦鹉螺(N.pompilius)的针孔相机眼包含一个可调节的瞳孔，可以根据光线强度的变化而放大或收缩。对这种瞳孔反射的动力学进行了研究。对光照强度突然增强的反应，瞳孔关闭时间约为90 S。对光照强度减弱的反应，睁开时间约为50 S。刺激1只眼睛可使未受刺激的眼睛的瞳孔收缩。这种反应的时间进程与同侧刺激实验中看到的不同。
The pinhole camera eye of the chambered nautilus, N. pompilius, contains an adjustable pupil which dilates or constricts in response to changes in light intensity. The dynamics of this pupillary reflex were studied. Closing times for the pupil in response to a sudden increase in light intensity were on the order of 90 s. Opening times in response to decreased light intensity were about 50 s. Stimulation of 1 eye caused a constriction of the pupil in the unstimulated eye. The time course of this response was different from that seen in the ipsilateral stimulation experiments.
