    The study examined the dorsal skin of three Millivora Capenesis, focusing on the histological structure of the dermis. The dermis was found to consist of two layers: the papillary layer, made of loose connective tissue with abundant collagenous fibers, few elastic fibers, blood capillaries, a large artery, a large vein, and Meissner and Pacinian corpuscles; and the reticular layer, containing dense connective tissue with skin appendages such as hair, sebaceous glands, and sweat glands. Two types of hair follicles, primary and secondary, were identified. Sebaceous glands were alveolar and surrounded hair follicles, while sweat glands were simple saccular glands lined by low cuboidal epithelium, with ducts lined by stratified cuboidal epithelium. Meissner corpuscles were located in the papillary layer, and Pacinian corpuscles were found in the reticular layer, both appearing onion-shaped.
