This was our first actual attempt at breeding snakes. And now the time has come to let my young slither the coop. They are two and a half months old, and most breeders would have already sold them buy now. I've been advertising them at the local pet shop, but only for about a week. I wanted to make sure they were good, established eaters before sending them to what I hope will be their forever home.
Forever home. That's what bothers me. I worry that their new owner will be a moron. It's harsh, I know, but I worry the snake will not receive the proper care. That they won't provide for their needs, and that they will die. My husband lives by 'out of sight, out of mind.' I don't live that way.
I watched these guys hatch, I held them as we moved them to their temporary home. I cleaned their tank, I purchased their food and watched them learn how to eat, how to sustain. I've watched them grow, oh how fat as sassy they are now! And one I call Stripe, such an aggressive little guy he is, not mellow and laid back like his siblings. He's a climber, he hates being on the floor of the tank. He gets as high up as he can go and dangles from the branches. As you can see, I'm attached.
Our first buyer is coming Sunday to pick out his new snake. In our brief conversation about snakes, I started nit picking the things that he said. I've already started to worry. Of course each buyer will be told that the option for us to take them back is always on the table, regardless of the shape they are in. I would hope they wouldn't be unhealthy, but we've nursed a many back to health, and I'll do it again if it will save them.
Of course the keeping them all is not an option. Right now we have ten snakes, seven of which are ball pythons. Time, money and not to forget space--is an issue, and while feeding them hopper mice isn't expensive now, it won't be long before they're feeding on more expensive meals and we draw the line at breeding prey.
My husband has insisted I make a better flyer than what I have posted, so that is my project for this weekend. And on Sunday, I'll wave goodbye to one of these guys. But you can bet I'll steer him away from Stripe.
Just because I never did well climbing the rope doesn't mean I don't find it fascinating how a snake does it. And I'm not the only one.
From Science Daily:
[University of Cincinnati] researchers sent the snakes climbing up varying widths and tensions of ropes as they explored snake movement in relation to their musculoskeletal design and variation in their environment.
They found that regardless of diameter or flexibility of the rope, the snakes alternated curving between left and right as they climbed the ropes. On the thicker ropes, they were able to move greater portions of their bodies forward as they climbed. As the ropes became thinner and more flimsy, the snakes used more of their bodies -- including their back, sides and belly -- to manipulate the rope for climbing.
"Despite the likely physical and energetic challenges, the benefits of the ability to move on narrow and compliant substrates might have large ecological implications for animals," write the authors. "Arboreal organisms must often feed or hunt in the terminal branch niche, which requires the ability to move safely on narrow and compliant substrates."
Of course, now I want to get some rope and head into the reptile room.

I think that one thing many passionate herpers realize, at some point, is how much they don't know and how much there really is to know about herps.
There's 2 species of tuatara, 23 species of crocodilians, 300ish of chelonians, 3,000ish of snakes, 3800ish of lizards, and Amphisbaenia. In amphibians, there's 5,000+ species in Anura (frogs and toads), 500+ species of Caudates, and something like 150 caecilians.
All told, that's north of 12,000 species of extant herps. There's no human way to know everything about every species. Factor in life histories, evolutionary histories, taxonomy and cladistics, physiology...there's more data to be learned than any one person ever could.
So, there's this huge mess of information; how do you go about obtaining it, processing it and using it for your captive herps (if applicable)?
There's lots of options, and most of them benefit from the inclusion of each other and none of them is perfect and entire unto itself.
You can read. There' s a plethora of herp literature out there. Some of it is very specific, some of it is very general. Lots of it is crap, but there's enough good stuff out there that you can go broke buying it all, no matter how much money you have (unless Bill Gates is reading this). Some books are very geared at keeping herps as captives, some are more geared towards dealing with natural history, others synthesize loads of research (on herps in general, or one genus or species in particular). Of these, I tend to favor the latter two types. You can, if you read and digest the information, learn how to care for an animal based on it's life history. You don't usually learn too much of it's life history from most pet-trade books though.
There's at least two good general books for snakes that are accessible to non-degree holding herpers; the older of the two is Harry Greene's "Snakes: The Evolution of Mystery in Nature." The other one is newer; it's "Secrets of the Snake Charmer" by John C Murphy. Of the two, Greene's is an easier read, but Murphy's is much more current and goes into a bit more depth. For lizards, there's "Lizards: Windows to the Evolution of Diversity" by Pianka and Vitt.
For a broader approach, you might try Zug's "Herpetology" which is frequently used as an introductory text in college classes. I'm currently unaware of a similar book for chelonians or crocodilians, which is unfortunate (if any commentators want to enlighten me please do!).
It's important to remember, while reading, that lots of things are cross applicable; hunting and predation avoidance strategies tend to be repeated across lots of different snake species for instance (how many snakes can accurately be described as foraging, how many make some sort of noise to try to warn/scare off predators?). Once you start learning, just in general about different strategies for coping with the demands of life, you may be able to interpret behavior you observe more intelligently--and you might understand why certain husbandry concerns are so common (why are hide spots important? Why are moist hides sometimes so useful?).
You can also go and look for herps in the field; find out what sort of conditions they seek out. What times are they active? What seems to increase or decrease activity? Are they usually active at certain times or certain temperatures? After or during storms? What habitat and microhabitat are they in? This can be very tough to learn to do, there's lots of trial and error and sometimes blood involved; this season alone I've wound up with prickly pear spines in my thighs, groin, and hand, I've fallen down a river crossing and gotten both half drowned and bruised, I've gotten bit several times, all in pursuit of finding herps in the wild. But it's very educational, as well as fun. One thing you can do to help get started is find a good regional field guide; check with your state herp society on which ones they like. This is an excellent example of how different methods of learning about herps can help reinforce each other. If you just went through trial and error it might be years before you found a target species, or learned how to read the weather to know if it was worth going out. Read a bit and apply what you've read to save yourself some major headaches. But just reading isn't nearly as satisfying as finding and doing--nor is it, by itself, enough to really understand herps. You won't learn to really read a snake's body language from a book for instance.
But I digress. Read a little first, and then go herping. Particularly if you keep native species this can be very enlightening. But even if you don't, you can observe wonderful behaviors; hunting, eating, mating, courting, territorial displays. I've seen coachwhips going into birds nest, a diamondback eating a small rabbit, collared lizards sparring...I've seen gravid water snakes basking in a protected section of reeds, I've seen them prowling for fish and frogs. These are all things that can both inform you knowledge and your husbandry. In a very direct sense seeing that collared lizards are very territorial helps explain why males shouldn't be more than one to a cage. Seeing gravid snakes basking the swollen, egg filled portions of their bodies helps reinforce the need to let gravid females have warm temperatures. Watching a coachwhip climb 20' into a tree and rob a nest helps you to understand what the field guide meant when it called coachwhips agile, lithe snakes. Seeing a rattlesnake strike a rabbit, withdraw, let the rabbit die and then consume the rabbit is an object lesson on the way venom works (I'm much more careful after watching that). Seeing a kingsnake grab a racerunner out from a yucca stump taught me about prey tracking, thermoregulation and it's importance, the fact that sometimes snakes will move to cover while constricting, and more. Those are experiences that no book can impart to you on such a visceral level--but then, books can teach you about things you'll never be able to observe too. I doubt I'll ever go to Thailand to field herp for reticulated pythons. I doubt I'll ever spend enough time in the Southwest herping to write a book like "Lizards of the American Southwest" (edited by Jones and Lovich, contributed to by many authors).
You can use the internet. Remember what I said about a lot of literature being crap? Well, that goes triple online. A lot of what you'll see on websites is junk. But there's also a ton of good information out there. Check out the forums here at kingsnake; there's herp luminaries that post here on a semi-regular basis. Wonder about how to work with Asian ratsnakes? Pro Exotics works with them and post here. Curious about what sort of herps you might find in Bangkok? I'm sure there's a handful of Thai people that read the forum. Questions about venom? There's some experts that post here (even if Dr. Fry is out with a broken back for now). It's certainly not perfect; there's little accountability online after all. But there's much to be learned from decent websites and forums.
All of these help to reinforce each other, and you should really do all of them if you want to learn about herps.
You may not be able to learn everything about herps; but you can learn a lot and in doing so, you can better understand captive husbandry. I know I'm a better keeper due to my field herping, and my reading of non-pet focused books. More than that, I'm better informed about the world around me.
Fossils and dinosaurs enthrall us herpers, and they hold the key to a variety of questions -- such as, "When did fangs develop?"
Jon Mitchell, a Chicago Paleontologist has found the answer to that question. From New Scientist.com:
A SET of 200-million-year-old teeth from a beast related to dinosaurs and crocodiles has shed light on how snake fangs evolved. They support the idea that venom canals inside fangs evolved from grooves on the tooth surface.
The late Triassic reptile Uatchitodon is known only from its teeth, which resemble tall, serrated crocodile or dinosaur teeth. Several have been found, and the two youngest ones, dating from 220 million years ago, have what look like venom canals. An older set have grooves of different depths but no canals. Until now it was unknown whether the variations reflected evolutionary changes, different stages of tooth development, or even teeth from different positions in the mouth.
Yet another cool discovery on our cold-blooded friends.

Kerry King, python breeder and guitarist for the legendary thrash metal band Slayer, will stop by our chat room over the holidays while he is on a tour break and talk with kingsnake.com users about keeping and breeding carpet pythons. After a summer touring Europe with Metallica, Megadeth, and Anthrax, Kerry is finally back home and has time to work with and talk about his snakes.
An old-school reptile keeper who learned his craft from masters like Lloyd Lemke and the west coast reptile mafia of the 70s and 80s, Kerry has been a longtime kingsnake.com user and has participated in a number of special events on the site over the years. Kerry usually posts to our classifieds under his Psychotic Exotics brand when he has stock available, and even has a few posted right now.
Kerry is checking his schedule to try to squeeze in a chat with our users (hopefully before Christmas), so get your questions ready. Watch this space for firm details on a time and date, but if you can't wait that long to get your Slayer on, check out these chat transcripts and interviews from our archives:
