We studied ultrastructure of the photoreceptor cells in the pineal organ of blind, depigmented, neotenic cave salamander, Proteus anguinus. Unlike in epigean vertebrates the outer segments of most photoreceptor cells consists of concentrically arranged lamellae, however; in few cells, the outer segments contain 7-9 plasma membrane disks. In both types of photoreceptor cells the outer segments enclose lumps of vesicles of different sizes. The photoreceptor cells of Proteus anguinus are similar to those in other cavernicolous fish species.
我们研究了盲态、色素脱失、幼态延续的洞穴蝾螈（洞螈）松果体中光感受器细胞的超微结构。然而，与地表脊椎动物不同，大多数光感受器细胞的外段由同心排列的薄片组成；在少数细胞中，外段含有7 - 9个质膜盘。在这两种类型的光感受器细胞中，外段都包围着大小不同的囊泡团块。洞螈的光感受器细胞与其他洞穴鱼类的光感受器细胞相似。
