|Black Gap Alterna
Young adult. This snake has undergone a tremendous visual transformation as it has matured. In life the gray on this animal is a beautiful, dark charcoal with deep bluish, gunmetal overtones. The orange saddles have been heavily invaded by black pigment and will most likely be nearly obliterated as this animal matures. Note that the white saddle edging is at most one scale wide in contrast to the trademark white "halo" effect these alterna often display. The dark pigmenting process this snake is undergoing has gradually invaded the white, in effect canceling the halo effect.
