| 摘 要： | 甲壳动物具有明显的视觉运动反应。这种对视野内移动目标的反应有两种形式,一种是眼柄的颤动反应(Optokinetic response),另一种为全身性的视觉运动反应(Optomotor response)。对于前一种反应形式国外已有许多研究,尤其对爬行亚目某些种类眼柄颤动反应特点和机制进行了大量实验。后一种反应形式的研究工作较少。有关游泳亚目视觉

THE SENSIBILITY OF YOUNG PROWN TO MOVING ORJECT AND ITS RELATION WITH ENVIRONMENTAL ILLUMINATION |
| |
| Abstract: | In this paper, by means of optomotor reaction, We study the receptive ability oi young Penaeus orientalis to moving objects and its relation with the environmental illumination. The results are as follows: The receptive ability of young prawns to moving objects increases non-linearly with the intensification of the environmental illumination, under the highest illumination(103lx) and lowest illumination (10-3lx) in this experiment, the prawns can distinguish the direction of moving objects at frequency 37/s and 5/s. The prawns may have scotopic aad photopic visions, and the transitional illumination between these two visions is 10-1-10+1 lx). |
