The surfaces of the ventral skin in B. gargarizans and P. nigromaculatus by SEM. SEM observations of the ventral skin in B. gargarizans and P. nigromaculatus. Surfaces of the ventral skin in B. gargarizans (A–J) and P. nigromaculatus (K–S). Plate in the ventral skins and granular gland (A,B). Ventral skin with superfine holes (C,D) and a scaly cuticle (E). Scale debris on skin with superfine holes (F,H). Superfine holes on the skin (I,J). Boundary among stratum corneum cells (K–N) with superfine fluff (M–O). Some fluff falls off and leaves a smooth surface (P,Q). The horny surface smashes, detaches and forms ultrafine pores (R,S). The white arrow shows the boundary among stratum corneum cells, and the black arrow shows the horny ultrafine pore. B, D, G, H, J, L, M, O, Q and S show enlarged images of the boxes in A, C, F, G, I, K, L, N, P and R, respectively. Scale bar, A: 500 μm; B: 250 μm; C, G, I, M, N, P, R: 5 μm; D-E, H, J, O, Q, S: 2 μm; F: 20 μm; K: 100 μm; L: 30 μm.
