The surfaces of the dorsal skin in B. gargarizans and P. nigromaculatus by SEM. SEM observations of the dorsal skin in B. gargarizans, P. nigromaculatus. Horny surface (A,C,D) and shards (D) in the dorsal skin of B. gargarizans. (B) Deep groove of the dorsal skin, boundary among stratum corneum cells (E,G), shallow groove (F), and regular ring structure (G,H) in the dorsal skin of P. nigromaculatus. The white thick arrow shows the groove, and the white thin arrow shows the boundary among stratum corneum cells. D and H show enlarged images of the boxes in C and G, respectively. Scale bar, A, C, E, G: 5 μm; B, F: 50 μm; D, H: 2 μm.
