The medial caudal artery, being a continuation of the aorta, ensures blood transport to all tissues of the caudal part of the dolphin body and its caudal fins. The branches of this artery are accompanied with some veins (complex vessels). In the microcirculatory bed there are many arteriolo-venulous anastomoses. The greatest attention of the author has been paid to the capillaries of the dermal pappilae which deeply penetrate into epidermis. It is possible to think that in this way: a) thermoregulation is improved; b) a greater hydroelastic effect is reached; c) epidermis blood supply is facilitated; d) certain conditions are created for synthesis of the dermal excretion.
