I purchased a pair of Dumerils boas in 1998. They are voracious rat eaters (the male will not eat mice) and have nice salmon necks. The female is larger with less color, but a more contrasting pattern. They are very docile except during feeding. They are a short fat boa and are strictly ground dwelling. I no longer keep this species because I have focused my collection to Rainbowboas.
The picture with me is an extra adult male for a size reference.
