The relative effect of light in inducing downward movements of the tips of isolated arms of Asterias amurensis is maximal at 485 millimicrons when the compound ocellus is intact; at 504 millimicrons when the ocellus has been removed. This finding suggests the coexistence of two photoreceptive systems, ocellar and nonocellar.
当完整的复眼存在时，诱导孤立星状臂尖端向下运动的光的相对效果在 485 毫微米处最大；当复眼被移除时，在 504 毫微米处最大。这一发现表明存在两种光感受器系统，眼状的和非眼状的。
