SEM photomicrographs of the ventral skin of the juvenile starry puffer fish showing: (a-c) The epidermal surface was represented by interrupted folds (long arrows), openings of the mucous glands (twisted arrows), several symmetrically-sized sensory cells (short arrows). d-f The epidermal surface between the folds was discernible in deep epithelial cells with compact, extensive, and erratically arranged microridges. g-i The epidermal surface of the folds and depressions in between (g). Note in (h) the adjacent deep epithelial cells were demarcated from each other by well-distinct borders like ridges (arrowheads) and in (i) the superficial epithelial cells with concentrically organized microridges (twisted arrows)
