Figure 3. SEM images of dorsal scales of B. rhinoceros.

(a) Microornamentation at a black dorsal scale, leaf-like structures at the surface (P). (b–c) Branched ridges at the surface of the leaf-like structures at a black dorsal scale. Ridges are regularly connected by thin struts. Pits are located between struts and ridges. (d) Ridges with spinules (S) between the leaf-like structures at a black dorsal scale. (e) Verrucate pattern at a pale dorsal scale. (f–g) Pits on the surface of a pale dorsal scale.
