***New Suboc Genetics Findings
There are a couple of new findings in the realm of suboc color morph genetics that I believe many of you would find interesting.
#1) First off, it has now been proven beyond all doubt that the European and Loma Alta/Hwy. 277 lineages of Albino Trans-Pecos Ratsnakes are the SAME genetically.
Here's the story: Gregg Feaster bred a het for European Albino male to a Het for Loma Alta, Texas Albino female and got Albinos recently. Some of you may remember that I got a single Albino baby from a similar cross in '06.
Why this is a big deal? Because this is one of the few times in the history of ANY high-end color morph of ANY species where you can OUTCROSS to strengthen bloodlines using homozygous to homozygous breedings -- in other words, Loma Alta Albinos bred to European Albinos -- and STILL get ALL ALBINO babies.
#2) Big year for Gregg Feaster...he also proved that the Dave Hewitt River Road Axanthics are genetically the same as the Mark Bell (and Trumbower) Axanthics, which are the ones usually seen for sale by breeders.
More soon!

"Bug-eyes" in Trans-Pecos Ratsnakes, an evolutionary adaptation

This doesn't happen often, but sometimes I talk to people who are laboring under the myth that "bug-eyes" in Trans-Pecos Ratsnakes is a result of captive inbreeding. This is well-documented for leucistic Pantherophis obsoletus lindheimeri, but for Bogertophis, nothing could be further from the truth.
Trans-Pecos Ratsnakes are fossorial during the day and 100% nocturnal otherwise. In other words, they're constantly in complete darkness -- in fact, in the wild, they absolutely shun light. "Bug-eyes" is an evolutionary adaptation to this lifestyle. And bug-eyes is not only seen in TPRSs -- it, as a physical trait, has convergently evolved in many unrelated taxa of animals with similar nocturnal habits. Owls, Leaf-tailed Geckos of the genus Uroplatus (among many other gekkonids), tarsiers, Red-eyed Tree Frogs, and the list goes on and on. Another example of "bug-eyes" in completely nocturnal snakes is Gray-banded Kingsnakes. Their lifestyle is much more fossorial and nocturnal than most Lampropeltis, and so they have those bulging eyes, which is a disharmonic trait for a kingsnake species.
And there is no deleterious allele in subocs that causes extra or excessive "bug-eyedness" when subocs are inbred. In fact, of the 115 subocs in my facility, some of the most bug-eyed are from parents that were caught hundreds of miles apart -- the furthest thing from inbreeding.
So, in conclusion, though "no bug eyes" might be a selling point for leucistic Texas Rats, it's not desirable, healthy, or normal to have a TPRS without them!
I mean, can you imagine someone selling a tarsier on the "selling point" that it has "NO bug eyes!"? 
Have a great weekend, all.

54 Trans-Pecos Ratsnake eggs and counting...

Soon, I will have some informational articles on Suboc.com (I know I've been saying that for awhile now, but bear with me) and an updated expected offspring for '08 list.
Here's a short list of what we have incubating so far:
- Pandale Gray phase
- Orange x Oro del Rio phase (Panther Canyon) -- should be some nice orange animals
- Triple Het x Triple Het -- morphs galore!
- Triple Het x 66% poss. Het Albino clutch #1 -- fingers crossed for Albinos
- Triple Het x 66% poss. Het Albino clutch #2 -- fingers crossed for Albinos
- Mustard Blonde x Oro del Rio (Orange) **aka Het "Strawberry Blonde"
- Mustard Blonde, Het Axanthic (Silver), 50% poss. Het Snow x Bleached Blonde -- should be all Blonde-patterned babies with SEVERAL possible colors
- Langtry x Black Gap -- just beautiful "Normal" Trans-Pecos Ratsnakes from beautiful parents
- Triple Het x Axanthic (Silver) Blonde, Het Snow -- morphs galore again!
Cheers!

Sharing a Closet with Incubating Reptile Eggs

I often hear, at least once a year, that someone I know lost ALL of their incubating eggs due to a malfunctioned incubator that overheated and killed them. Ugggghhh!!! That would be such a kick in the stomach!!...all of that year's long hard work gone to waste in a matter of seconds.
Something different I'm doing this year should mitigate or throw out entirely that possibility of an overheated incubator. My egg boxes, each with a clutch, are stacked on the highest shelf in a closed closet. By itself, the closet stays about 78 - 80 F. If you add a couple of heat pads and use them as "panels" against the wall, you can bump that up to about 86 degrees. That's with the heat pads on full power. If you connect them to a rheostat, which further mitigates any risk of overheating, you can lower the heat pad temps enough to bring the ambient temperature down to marginally above that of the closet's natural temperature of 78 - 80 F. Of course, you don't have to use any heat. (Suboc eggs have been proven to hatch at temperatures as low as 40 degrees!) But it takes longer that way, if you don't mind the wait.
So far, this season we have more than 45 eggs incubating, 42 of which appear good. Only a couple more females to go, maybe three, but they're good ones.

More soon!DR

How to be Good Stewards of the Earth and Conservation-minded While Still Enjoying Herpetoculture
I gathered from our conversation that these were people who were probably not "mainstream" in the modern pet reptile industry. It just seemed that they would probably catch as many of whatever they could find on their property and sell them to anyone who would buy them...which is the way that most reptiles were bought and sold back in the early 1980's and previous to that. Now, I realize that there is still a market for wild-caught reptiles, but that market has changed drastically over the past 15 years. Nowadays, most people -- both buyers and sellers -- deal in captive-bred only.
I explained to these people that they would probably have more long-lasting success if they only sold young snakes that they had legally caught. There are many, many reasons for this:
- First, young snakes aren't as picky eaters and will eat feeder lab mice -- the adults often only eat K-Rats and Deer Mice and will die a long, slow, stressful, and cruel death in captivity if they never switch to lab rodents (many won't).
- Second, young snakes are much more adaptable to captive situations and stresses -- they're naive and haven't had to duke it out over territory or evade predation as long as adults have.
- Third, young wild snakes are usually scar- and blemish-free...older snakes often have the battle-wounds that go along with being a wild animal. And only adult subocs carry blood-sucking ticks on their bodies.
- Fourth, female snakes can and do store sperm from previous breedings and will often use those stores instead of the male they currently are breeding with. The surest way to know the genetics of your captive-bred suboc babies is to raise up young animals.
- Fifth, only a small percentage of young snakes survive to adulthood to reproduce. Large snakes have proven their fitness; they have won territories; they've evaded enough peccaries, owls, foxes, and other predators to stay alive for several years, AND they've proven that they can stay alive long enough to make MORE suboc babies...
- And this leads me to my sixth and final point -- and this is the biggy -- if you only take young snakes from the wild, the older established adults will still be around to provide you with MORE young snakes as long as they are alive.
I cringe somewhat when I see people selling literally bucketloads of every species of herp they can find near their home. To me this behavior smacks of prodigal wastefulness and disregard for conservation of wildlife. I believe that animals, plants, mountains, minerals, valleys, rivers, oceans, and all components that make up what we call nature were put on this earth to bring us joy and gladden our hearts -- not for our unfettered usage. I truly believe that to my very center. It would be a sad situation indeed if we continue to lose the many species that exist among us due to our own irresponsible wastefulness and greed.
Just as there are bag limits and other restrictions on the take of White-tailed Deer, there are bag limits and restrictions on the take of reptiles in most states. Please respect those laws and regulations. Just as you shouldn't shoot a deer that walks into your yard, you shouldn't take every herp that does the same. Does that mean you can't take some? Of course, not...but please respect laws, regulations, bag limits etc. and always ask yourself if you are being a good steward of the earth and its inhabitants. If you can answer that question honestly and in the affirmative, then your efforts are commendable.
Let us see how our presence on the earth can benefit other species, instead of the other way around. So many people live in a "scarcity mindset"...i.e. there isn't enough money; there aren't enough jobs, there isn't enough land, etc. for everyone to live abundantly and happily. I believe there is enough, and though there will always be poor people, there will also always be a way for us to help and teach others to be more self-reliant. A more educated people are able to do more, whether it be earning their own bread or having the ways and means to be better stewards. We see time and again in undeveloped nations (where there are many illiterate, uneducated, and impoverished people) that they often use up their natural resources and sell them in the "bushmeat" or black markets. There is much we can do to reverse that trend. It will take entrepreneurs, biologists, students, farmers, missionaries, doctors, teachers, and many others to make this a reality, so there is room enough for everyone to help.

New SLR camera and NINE good Triple Het x Triple Het Suboc (Trans-Pecos) Eggs...
All in one day too!
I really wasn't expecting that many from her. I thought six, maybe seven...but Nine I can definitely handle.Anyway, this camera takes HUGE pics, like 12.2 megapixels...and I wanted you to see the macro somewhat so here it goes.
Practically every simple recessive suboc morph you can think of could come out of this clutch, even a Snow Blonde, which has not occured yet. A Snow Blonde, if it were to occur, would be the very first triple recessive homozygous morph of subocularis.

Gray phase eggs
She laid them quicly and without complication.
In other news, Triple Het eggs should be laid any day now...mommy's scouting for a place to deposit her clutch.
