Abstract: The retina in Andrias davidianus were observed with light and scanning electron microscope.It is found that:There are about 130000 photoreceptors and 8000 ganglion cells per retina.The rate of rod to cone is 8.5∶1.The hree nuclear layers and the two plexform layers are evenly dispersed in the retina.No forea centralis is faunded.On the surface of both rod and cone,there are 20-30 calycal processes on the outer segment and 20-30 plasma processes which extended from perinuclear body.But,typical interlobuar furrows were only observed on the outer segment of rod.The structure of larval retina was also studied.At last,the relationship between the structure and function is discussed.
