Pattern and color:
- V.t.orientalis lack the melanistic pattern of
V.t.tristis and can further be distinguished by the less spiny scales on the
tail. Both are brightly colored as hatchlings, but V.t.orientalis retain
most of their young pattern while in V.t.tristis the pattern darkens and is
replaced with varying amounts of black as the animals grow.
- Males have clusters of spines on either side of
the tail base. These spines are much reduced or absent in females.
