Movat staining of skin samples from three Galápagos iguana species. (A) The image shows the presence of collagen fibers (yellow) in the superficial loose dermis of black-colored A.cristatus skin. (B) The image displays the presence of sparse collagen fibers (yellow) in the superficial loose dermis of black-colored C. marthae skin. (C-E) No/rare collagen fibers are present in the non-black-colored skin (pink) of C. marthae (C) and C. subcristatus (D) as well as in the black-colored skin of C. subcristatus (E). Scale bar = 100 μm
