Figure 3. Scanning electron photomicrographs show the scale
microstructure in P. urarachnoides : upper Head scales (A,
~100X , B, 1000X and C, 8000), caudal appendage (D,
~100X), and knob-like structure (E,
~100X and F, 5000X).
The microstructure of head and mid-body dorsal scales inEristicophis macmahonii resemble a lattice-like structure.
However, the depressions in these net-like structures are more or less
roundish on head but elongated and more or less diamond-like on the
mid-body scales. Tiny spicules are observed on the surface of both head
and mid-body scales (Figure 4).
