摘要: Skin specimens were obtained from every representative region of the body an adult Finback whale (Balaenoptera physalus) and examined by means various histochemical histological techniques. The following characteristic features found: The epidermis is exceedingly thick over general surfaces varies a maximum 3.0 mm ventral surface to 2.5 on back. The complex understructure has rete ridges oriented craniocaudad axis. The papillary layer dermis long pointed papillae which are wedged into epidermis. The sensory cutaneous nerve endings demonstrated silver impregnation cholinesterase consist predominantly small Vater-Pacini corpuscles situated in higher level dermis. The intricate blood capillary network, positive for alkaline phosphatase encased dermal papillae. There no hair follicles, sebaceous sweat glands.
