Elaphe [guttata] emoryi

The great plains ratsnakes are found throughout all of Texas but the northeastern tip. They have recently been removed from the guttata group and elevated to their own species level.
They are usually referred to by the local herpers as "Emory's."
They are fairly common throughout the state, although they seem to be more common in the plains environments than in the montane areas.
There is some minor variation in there coloration in different areas. Some areas have a lighter ground color than others, some areas have more black surrounding the blotches but, for the most part, they look very similar.
They can be somewhat defensive when captured and can stay that way for a while in collections. They usually calm down after a while. They usually feed well on rodents, but will eat birds and lizards in the wild.
