Yearling male. This is an unusually colored juvenile. In life, the borders of the oddly shaped nuchal saddles are boldly chased with bright white that the camera does not pick up. White pigment on the nuchals of deppei usually expands greatly with maturity.
This series of juvenile Durango Mountain Pine Snakes (Los Mimbres locality) will be the last to be offered by Vivid Reptiles.
