Gross anatomy and ultrastructure of Moorish Gecko, Tarentola mauritanica skin

The epidermis of Tarentola mauritanica in the skin regions of back, flank and belly has been described using light and electron microscopy. This animal model was useful to give an insight of the functional pattern involved in pigmentation, cryptism and photosensitivity. Skin from back and flanks, in electron microscopy, shows a high concentration of chromatophores, among those melanophores, xanthophores and iridophores have been reported. Interestingly, in the flank-back transition region electron microscopy reveals the presence of nerve endings. Our contribution adds new knowledge about the skin of this species, and it could be useful to study in deep the mechanism of cryptic colour change in reptiles.
