| Abstract: | Electron microscopy of the cornea have been performed in marine fishes. Some structural peculiarities in the cornea of prebottom-dwelling fishes have been demonstrated. In Gobius fluviatilis (Pallas), Gobius (Proterorhinus) marmoratus (Pallas), glossa Platichthys flesus (L) the cornea is double and there is an iridescent layer. It is stated that cells of the iridescent layer play an active part in the formation of the endothelial basal membrane. In Syngnathus nigrolineatus, according to its living conditions, the cornea has a rather simple composition and structure. In the cornea of fishes either epithelial or endothelial basal membrane (Gobiidae, Syngnathus nigrolineatus) or a wide electron opaque epithelial membrane (Blennius tentacularis) or else, besides this, the Bowmen membrane (glossa) can be formed. |
