|River Road Alterna|
Adult. Both alterna and blair's phase patterns occur on the River Road, the alterna phases being the more common type. There has always been disagreement amongst alterna aficionados as to which phase category an animal like the one pictured above belongs. Purists will contend that animals with any orange banding at all are blair's phase while moderates believe that if the orange is greater than "X" number of scales in width it is a blairs and below "X" it is an alterna phase. At Vivid we simply call animals such as this specimen "intermediates" and use the term as a catch-all for the myriad of middle ground blair's/alterna pattern types.
