Figure 5. Scanning electron photomicrographs show the scale
microstructure in C. gasperettii : upper head scales (A, 782X; B,
750X), mid-dorsal scales (C, 3000X), and caudal scales (D, 750X).
These prominences are shorter on the tail than on the other two parts.
The scale microstructure of dorsal scales in E. carinatus appear
as eggs in a tray, mostly similar to the upper head and mid-body scale
surface in C. gasperettii (Figure 6).
