"These beautifully marked Boas have a light, beige to white background color as juveniles with very distinct black body blotches and an exaggerated black Head spear. Youngsters may also show hints of pink in between the saddles and down their sides. As they mature their rust colored tails turn to an almost jet black and the overall background color darkens. They have a high dorsal saddle count from snout to vent of 26 – 29. The dark color is most likely an evolutionary response to create an easier way of absorbing more heat in its high elevation habitat"


What was striking about this snake when I met her was the jet black coloring mixed with hints of pink and orange (especially on the belly).

And the extented head spear is there as well.

Is this any help, or also typical of any Mexican locality boa?
Sonoran boas exhibit similar colors. You could e-mail Russo a photo and see if he can ID it - but remember, the tarahumara is a locality of a sonoran. The fact that this one is fairly large may be indicative it's something else.
