SEM photomicrographs of the dorsal skin of the juvenile starry puffer fish showing: (a, b) Epidermal surface characterized by the presence of delicate irregular-shaped protrusions with depressed centers (arrowheads), and a row of slightly buried superficial sensory cells (short arrows). c Each sensory cell was characterized by the presence of several pores (arrow). d, e High magnification of the epidermal surface between protrusions.
