Ventral epidermal ultrastructure of the amphibian urodele Salamandra salamandra is described and followed throughout its life cycle. Tadpoles were divided into five categories on the basis of the organization of their epidermis and the ultrastructure of its cells. In newly hatched tadpoles the epidermis is arranged in two layers and four types of cells were recognized. The number of epidermal layers increases in the metamorphosing tadpole. At this stage the layers become organized in four strata. Metamorphosis involves the disappearance of some cell types and the appearance of others, typical of the adult epidermis. The significance of these ontogenetic changes in epidermal ultrastructure is discussed in respect to aquatic and terrestrial life habits.
描述了两栖类有尾目动物火蝾螈整个生命周期的腹侧表皮超微结构。根据表皮的组织结构及其细胞的超微结构，将蝌蚪分为五类。刚孵化出的蝌蚪表皮由两层组成，可识别出四种细胞类型。在变态期的蝌蚪中，表皮层数增加。在此阶段，这些层组织成四层。变态过程涉及一些细胞类型的消失和其他典型成年表皮细胞类型的出现。就水生和陆生生活习性而言，讨论了表皮超微结构这些个体发育变化的意义。
