Scales play a crucial role in the protection of fish, but, as recent research has shown, they also provide other valuable information. Although many techniques have been used to analyze scales, certain structural features have still not been properly characterized. To obtain the most information possible from scales, new procedures should be applied to their study, and state-of-the-art techniques of microscopy are among the methods worth considering. In this work, Stereo Microscopy and Atomic Force Microscopy were used to characterize the scales taken from six body locations of gilthead seabream (Sparus aurata—one of the most important fish in marine aquaculture). It was seen that the scales from the central parts of the skin are larger and the height of the circuli increases at the base of the dorsal fin and close to the head. Notable morphological differences are evident on the scale sizes and external microridges of the skin surface in contact with the skin mucus among different bo
