Emory Ratsnakes
(Elaphe emoryi)

 

Emory ratsnakes (aka Great Plains Ratsnakes) are the "other" cornsnakes that everyone talks about.  Emory ratsnakes are highly variable in body size, color, pattern, clutch size, etc.  This is mainly because they occur from Mexico up to Nebraska at varying altitudes and in various habitat types.  Regardless of the locality of the founding stock, Emory ratsnakes make excellent pets for the beginner and more experienced herper alike.  With all of the new, pure, morphs being developed, Emory ratsnakes are quickly moving to become one of the more popular ratsnakes out there!  The rumors that they make less docile pets than cornsnakes are, well, just rumors.  Our Emory ratsnakes are as docile as any of the other snakes in our collection!  Since they are much larger as hatchlings than cornsnakes, they tend to make better pets for younger hands (always supervise kids around pet snakes!) and can take larger pinks.  This can be a big benefit if you buy pinks from your local pet store that frequently lacks small pinks that are perfect for smaller cornsnakes!

Adult sizes range from being smaller than typical cornsnakes (less than 3' in total length) to being larger than the typical cornsnake (slightly over 5' in total length).  Clutch sizes range from 5 or 6 eggs per clutch to 12-17 eggs per clutch, but the babies generally start feeding on unscented pink mice MUCH easier than many cornsnake hatchlings.  Overall, adults and hatchlings are much stockier, heavy-bodied, animals than cornsnakes of the same length.  This means that the babies are generally hardier than the typical cornsnake - believe it or not!

A few years ago, we were privileged enough to purchase Don Soderberg's entire Emory ratsnake colony.  Combining his colony with the animals and projects we already had, we were able to form the most complete and extensive Emory ratsnake collection in the United States.   Through strict culling, hold-backs, and additional acquisitions, we have what we believe to be the best colony of Emory ratsnakes in the world!  When it comes to our Emory ratsnakes, expect only the highest level of quality and cutting edge projects in the upcoming years.

Emory ratsnakes are also one of the snakes that almost gave me a nervous breakdown.  We don't like man-made hybrids.  However, the Elaphe emoryi complex (formerly Elaphe guttata emoryi) has been in an upheaval for the last couple of decades.  Snakes that are okay one day to cross are getting called hybrids the next day.  Although I don't agree with the Elaphe emoryi emoryi/Elaphe emoryi meahllmorum split, that split was the recognized taxa in the US for a period of time.  Now it is back to being only Elaphe emoryi with no subspecies.  (Correction: it has been changed back to separate subspecies again!)  Elaphe guttata intermontana (which would be Elaphe emoryi intermontana now) hasn't been recognized officially for decades, but it is the most isolated and distinctive of all of the E. emoryi populations.  We still consider that a color phase in herpetoculture, though.  That is exactly how I'm going to have to interpret all of the different pseudo-groups of E. emoryi if I plan to keep my sanity.  That is how we are managing our colony, even though I like to use the subspecies terminology while out in the field.  Localities are given, when appropriate, in case another split is forthcoming in the next couple of decades.  (If anyone is interested, the middle half of Texas is considered a natural intergrade between the two subspecies.  All of the Bend Area of West Texas is considered an intergrade.  In other words, MANY of the E. emoryi entering captivity from the wild are intergrades that are bred freely, through ignorance, to pure subspecific specimens without any of us even knowing it.) 

On a final note, I am aware of the hypothesized taxonomic name change from Elaphe to Pantherophis (or even Pituophis).  Furthermore, I agree that a name change is warranted.  However, hobbyists have jumped on the name change - ignoring the fact that taxonomy is nothing more than a hypothesis of relationships - while ignoring the glaringly obvious problems with that study and the problems with prematurely accepting such a drastic name change.  Although I agree that a split is warranted, I'll await further developments before making a decision to use the newly hypothesized nomenclature. 

 

 

Intermontane Ratsnakes (Elaphe emoryi var. intermontana)

 

 
Intermontane ratsnakes, also called Great Basin Ratsnakes, are arguably the prettiest wild color phase of the Emory ratsnake in existence.  Whether that is true or not, this is definitely one of the most popular phases of ratsnakes that we have ever worked with.  The dorsal blotch count is roughly twice what is normally seen in an Emory ratsnake, each blotch is about half of the width of a typical Emory ratsnake's blotch, and the blotches become indistinct and almost nonexistent in the best looking Intermontane ratsnakes.  In some of our best adults, you can barely even count the blotches.  Mine are all descended from Colorado ratsnakes, so they are technically considered E. e. emoryi

My Intermontane ratsnakes are descended from Colorado stock where they occur in semi-isolated valleys.  These snakes are semi-isolated from each other and completely isolated from the main population of Emory ratsnakes further east.  This is the reason for their very unique appearance.  This also means that each valley has Emory ratsnakes that are unique in appearance from the other valleys due to this "pocket habitat."  Because of this, Intermontane ratsnakes can go from looking like a typical northern Emory ratsnake to being something distinctly unique like the ones in our colony.  Don't judge our Intermontane ratsnakes by what you've seen in other colonies from other valleys and always be sure of what you are getting regardless of where you purchase your Intermontane ratsnakes. 

 

 

Albino Emory Ratsnake (Elaphe emoryi var. emoryi )

 

 
Albino Emory ratsnakes have been around for a couple of years but are still very popular.  I believe this is due to their unique appearance and extremely beautiful color and patterns.  Albino Emory ratsnakes typically have strongly colored yellow to yellow-orange blotches on a stark white background.  With the distinct, unconnected, lateral blotches that are seen in Emory ratsnakes but not in pure cornsnakes, you have a much more distinct, intricate, pattern than we are used to seeing in albino colubrids.  I love albino cornsnakes, but they can never be as complex looking as an albino Emory ratsnake.  Most of ours are descended from animals that were originally captured in the vicinity of one county in Kansas, but some have been outcrossed.  We keep detailed records of our breeders to know which ones have and have not been outcrossed to E. emoryi from other localities.  If you have a preference, make sure to let us know!

 

 

Chocolate Emory Ratsnake (Elaphe emoryi var. emoryi )

 

 
Chocolate Emory ratsnakes are still very uncommon with very few having ever been sold.  Chocolate Emory ratsnakes are unique for the entire cornsnake/Emory ratsnake complex because they seem to be the first case of hypermelanism ever reproduced in captivity.  Their coloration goes from looking like a VERY brown Emory ratsnake through a milk chocolate coloration where the blotches are very indistinct to an almost brown-black hypermelanistic coloration.  On top of the coloration, chocolate Emory ratsnakes typically have each dorsal blotch split in half resulting in two paired blotches that look like mirror images on each side of the spine.  Through selective breeding, we are improving the overall "milk chocolate" coloration and split dorsal blotches of our colony.  We continue to have a lot of hope for this project.  Most of ours are descended from animals that were originally captured in the vicinity of one county in Kansas, but some have been outcrossed.  We keep detailed records of our breeders to know which ones have and have not been outcrossed to E. emoryi from other localities.  This morph, when combined with other traits, has the greatest potential to develop new, unique, looking snakes of any of the morphs with which we currently work.

 

 

Albino Chocolate Emory Ratsnake (Elaphe emoryi var. emoryi)

 

 
As the name says, this is what you get when you combine the albino and the chocolate gene in an Emory ratsnake.  Amazingly, this animal looks MUCH better in person than it does in a photo.  There have only been TWO albino chocolate Emory ratsnakes ever produced, and we own both of those individuals. The adult female is a beautiful overall yellow coloration with florescent pink patches. She was so brightly colored as a hatchling that she almost looked fake when I first saw her. Without a doubt, I consider this to be one of the best looking upcoming colubrid morphs out there.  The younger female is less than a year old at this time, and it far outshines the older female in coloration already.  Each shed brings more and more coloration out for us to enjoy.  

These are VERY hard to produce, and very few will be available over the next couple of years.  All of the original wild collected stock leading up to this morph came from southeast Kansas, so they are E. e. emoryi if you consider that nomenclature to be valid.

 

 

Emory Ratsnake (Elaphe emoryi) - Normals
 
These are normal Emory ratsnakes from (1) the southeastern portion of Kansas or (2) mixed - or unknown - locality adults.  All of the normal Emory ratsnakes that we produce are by-products of other projects, so they will be possible hets for one or more traits with which we work.  Combined, our colony of multiple hets can produce a LOT of different color morphs over the upcoming years.  We make sure to keep - and breed - some of these each year because we like the way the normals look and consider outcrossing to be so important in captive snakes.

 

 

Hypomelatistic Emory Ratsnake (Elaphe emoryi) - Type A Only, Wilstead/Mitchell bloodline

 

 
There are currently two different bloodlines of Hypomelanistic Emory ratsnakes.  "Type A" is the line that Troy Wilstead started and passed along to Brent Mitchell.  It is also called a ghost Emory ratsnake by some people.  This line traces back to a gravid wild-collected female.  This is by far the best looking line of true hypomelanistic Emory ratsnakes that I have ever seen.  This has been proven to be a simple recessive trait.  These snakes basically have "lavender-greenish-brown" blotches on a white background with the complex pattern so common to Emory ratsnakes.  We have never regretted getting into a bloodline of Emory ratsnakes that look this good.  Combining this mutation with other ones can only bring new, outstandingly colored, Emory ratsnakes!  In our opinion, the Type A Hypomelanistic Emory ratsnakes are definitely a pure E. emoryi without a shadow of a doubt.  However, there is some question over the subspecies that this line should be assigned to, and it is highly possible that it comes from the zone of intergredation in the wild. 

We are in the process of heavily outcrossing the hypo line since it seems to appear that some of the currently established lines of hypo Emory ratsnakes are suffering from problems associated with inbreeding.  We have as our #1 goal with this line all intents to heavily outcross it BEFORE those problems develop in out breeders here.

 

 

Reverse Striped Emory Ratsnake (Elaphe emoryi var. meahllmorum) - South Texas Line

 

 
All of our South Texas Emoryi ratsnakes are from the Hebbronville/Freer area.  These Emory ratsnakes are typically larger animals with larger clutch sizes than their more northern cousins. They have black, distinctive, blotches on a silver-grey background with little to no yellow or brown colors.  These are what anerythristic cornsnakes should  look like!  These are one of our favorite looking natural Emory ratsnakes. 

The only way to improve on the coloration and pattern of south Texas Emory ratsnakes is to combine it with the reverse striped gene.  Our reverse striped Emory ratsnakes were all produced by animals from the Hebbronville/Freer area of south Texas.  They have black, distinctive, blotches on a silver-grey background with no yellow or brown colors in them, but the blotches tend to be split along the spine to show a unique "reverse" stripe pattern.  This entire bloodline was sparked by one wild-caught male that demonstrated the reverse stripe pattern.  This pattern is definitely inheritable, but we aren't positive that it is a simple recessive trait yet.  It acts similar to one, though!  The degree of "reverse striping" is variable, with the later generations being more pronounced thanks to selective breeding.  These take our favorite natural coloration of the south Texas Emory ratsnakes and add even one more row of blotches to the top.  Without a doubt, they look great.  We plan to cross this into some of the other Emory ratsnake morphs to see what interesting color and pattern morphs will be developed.  We also produce some normal animals out of this bloodline that should be carriers for the reverse striped trait.  Although some are being crossed into other bloodlines, we will try to continue to maintain a pure south Texas group for those interested in the E. e. meahllmorum possible subspecies.
