It was posted by SRX. As I recall he/she is an anerythristic Longicauda. The boa shed and became the snake in the pic. I believe it was simply a normal appearing anery longi and then became an amazing anery after a shed. The anery gene in longis definitely varies from the Type I gene in Colombians. Anery longis don't "brown up" as Colombians do. Because of this, anery longis usually get better looking as they mature. That is a beautiful boa.

This is a possible het. anery longi. I'll post pics of my anerys soon. SRX's is definitely different.
