Abstract
The flat-headed goby, Luciogobius guttatus, inhabits tidepools and river mouths, and stays under stones on the dried bottom for the duration of the low tide. To know the relationship of its respiration and habit in this fish, the epidermis of five appendages was observed. The epidermis has three layers: the outermost layer, middle layer and stratum germinativum. The outermost layer is composed of polygonal cells or rather flattened cells, and mucous cells. The unicellular mucous cells showing acid mucopolysaccharides are 11.1 to $16.1{\mu}m$ in mean height and in one or two rows. The middle layer consists mainly of large epidermal cells that are swollen by adjacent epidermal cells and arranged in a web-shaped structure. The swollen cells are 12.3 to $15.2{\mu}m$ in mean height and arranged in one to 11 layers. Since the swollen cells occupy the entire height of the epidermis, the epidermis is thick. A large number of blood capillaries are present just below the stratum germinativum. Taste buds are distributed at intervals on the surface of the epidermis. Based on these epidermal strucures, it is likely that L. guttatus utilizes cutaneous respiration in a dual respiratory systems.
