ABSTRACT

A structure and adaptive features of epidermis of various fishes are analyzed in the paper. We consider the ways of excretion of mucus onto the body's surface, the action of it on the flow regime and the influence of both a body's shape and a speed of swimming on the topography of the secretory system. The mucus-producing function of the epidermis is shown to be determined by both the ecology surrounding a fish and the speed of swimming rather than by the stage of development of the scales.
