TerryD,
Is the dorsal coloration of the boas in your photo true to what they really are in life. From the photo, the darker one looks as if it has a hint of dark burnt-orange to it dorsal surface. Or is the darker boa simply a dark chocolate brown?

If the darker specimen does have a hint of burnt orange dorsally, is its ventral surface orange?

P.S. At the present time I am maintaining about 40 Rubber Boas most of which represent a line of investigation. Over half are subadults or juveniles. RFH
