  Surface constructs in snakes reflect desirable design traits for technical
surface engineering. Their micro-textural patterns, however, do not lend
themselves easily to unified analysis due to species-specific variations in
surface geometry and topology. Fractal description is useful in this context
since it accentuates the correspondence between patterns especially when
responding to tribological phenomena. In this work we examine the surface
construction of 14 snake species, representing five families, and evaluate the
fractal dimension for each of the skins (both the dorsal and ventral sides)
using three different computational algorithms. Our results indicate first that
all of the examined species share a common fractal dimension (with a very small
variation between species in the order 4-5%). This finding implies that despite
the different micro-geometry of texture among species, the skin as a unit
responds in a similar manner to many interfacial influences.
