Hypo Chinese Stripe-tailed Ratsnake Breeding Results (pics)...

Terry Cox Aug 16, 2004 08:38 AM

Actually, I only have one hypomelanistic Orthriophis t. taeniura, a male...

The female I mated him to is a "het. for calico" Chinese stripe-tail. They produced nine eggs back in mid-June, 2004. I incubated the eggs in a combination of vermiculite and perlite at about 82*F, with slight nighttime drops. The first eggs pipped the night of 8/10/04 after about 58-59 days...

I thought, if I was going to have trouble with any of the eggs, it would be the one on the very bottom. I thought the baby might not be able to get out of the egg. But, it turned out to be the one that came out of the egg first. I guess that's because it was closest to the heat source. (Theory: higher incubation temps shorten incubation time.)

The egg I had the most trouble with was the one which was the highest up on the stack. All other eggs had hatched by August 14th. On the morning of the 15th the last egg still had not pipped. I opened the egg in the middle and found there was a live baby inside. Later the snakeling pipped the end of the egg and the two openings made one long opening. Notice that all the eggs pipped naturally, eventually. The eggs shells had softened up considerably before pipping and the snakes didn't have any trouble cutting the shells and getting out...

The babies are cute. Most of them are a light greenish ground color with fairly typical t. taeniura patterning and black highlights. They are pretty large, around 14 inches, and all appear very healthy. One or two are a little darker than the others, and one is very light with a reduced pattern. I don't think being het. for hypo has much to do with the coloring, but I think some of the babies are also het. for calico, and that, in combination, may be making them look lighter...

Eventually, I'd like to produce hypo x calico double hets. I'm going to keep a pair of the hypo hets for this purpose.

I hope this info will help others with their taeniura breeding projects. I'd be interested in hearing other accounts and seeing some of those clutches. I'll probably post more baby pics once they shed for the first time and brighten up more. Good luck, all.

Hi Terry,

Has the calico coloration in O. taeniura ssp. been demonstrated as a single-gene recessive trait?

I just checked on google and found a lot of foreign language sites but did not take the time to run them through a translator.

Terry Cox Aug 16, 2004 05:23 PM

Yep! I have a male and female, both het. for calico, that I bred last year, and they produced my first calico t. taeniura...

This was when she was just born last summer. She's lots prettier now and close to three ft. I need to update her pics

I too did the same question to Terry 1-2 years ago,
now in Europe there are every year more calico and het calico on the market, this is a site of a breeder http://www.taeniura.nl/

hi,

I have breed 2 Het. Calico's to each other last year. I had 6 eggs but one was rot from the begin. After 60 days I opend one the eggs becuase normally they will hatch after 60 days. Later all the young snakes in the eggs seems to be dead. I had 2 calico's and 3 66% Hets. but all dead. The reasson for this was unknown. next year (2005) I will breed my Het. calico female to my Albino T male, so I produce 100% Het. Albino and 50% Het. calico. This year I have bought 7 Calico females to support my group. before I had only one female. In 2 years I will breed lots of Calico's and Het. Albino T . I have some nice projects to go in the future. Now I have a young Albino T-, and next year I will become some Anerythristic's. The only one I can't get in 2 years is the Hypo.

greetings,

compliment for your work Mark,
I hope to meet you in Hamm (have you a table?) or if i'll go in Utrecht, or if you'll come in the Reptiles Day in Italy.
regards
nazzza
ps
I was in Hamm but never in Utrecht, which is the better show for a colubrid enthusiast?

Terry Cox Aug 17, 2004 08:20 PM

Mark, sorry to hear that the babies from this year's clutch didn't survive. Two calicos too. That would've been nice. Hope things go better next year for ya. Those anerythristics look pretty nice too, eh?

PS: Anyone working with bimaculata over there, and when do you think we can expect some mutations over here, like with the taeniura? Haha

hi,

I will be at the reptile show in Hamm. I normally had a table over their but since the calico's and Hets. are dead in the egg I don't need a table in Hamm. I now only have 12 males of Taeniura Ssp and several couples of the Taeniura Friesei. I will sell them in Holland, in Tilburg (28 and 29 august) and in Utrecht (Houten). in 2006 I will have a lot of calico's and Het. Albino T and even Albino T- so then I will be at Hamm with a table.

He terry if you ever come to europe I will buy a 1.3 Het. Hypo Taeniura from you. Or maybe you know someone who will ship the snakes for me to germany or something?

greetings,
mark

later I will post some Pic's of my Calico T and T-

Hi, Mark. Sorry I didn't answer right away. I can't come to Europe, but I might find someone who can ship to you. Send me an e-mail in a week, or so, for an update.

PS: Your albino T's and calicos were awesome

Congrats Terry! Good work. Mine didn't go this year but they are gettign bigger for next year. We missed you at the show! Next year.

Cheers,
Glenn

Terry Cox Aug 17, 2004 08:07 PM

Thanks, Glenn. Hope you guys had a good time and nobody got hurt with Charlie and all. Did you have the dinner again? I hope I can make it next year, but we'll see.

Good luck with your taeniura next year. I sure have had some with my little group

Did anything happen with that albino bimaculata? Please e-mail me on that, so we can discuss some things. Later...

Terry, yes we had a good time in Daytona! Saw some nice animals. I especially like Karl's CB Porphy vaillanti and well as Rex's and karls CB Moellendorf's. There were several coxi there. I believe Steve Emerick is one of the only who had success with prasina this year. Oh I forgot Rex had a beautiful male conspic there too!

I can wait to try my dh hets this coming season. I just tihnk they needed to get a little bigger.

Mark, you have some nice animals over in Europe. Will you have an anery beauties this coming seaosn. I had a chance to get some from Wai here in California but I have not heard form him in some time. I may try to track him down.

Best regards,
Glenn

Terry Cox Aug 21, 2004 10:02 AM

Glenn, sounds like there was some great stuff there. I'm glad there's some that are carrying on with some of those great snakes. I'm cutting back on keeping the exotics. Hope I can make the show next year anyway.

I think Karl had some frenata too at home. I guess they didn't produce then? You should post a few pics of your taeniura. I know you have hypos, which I'd like to see. How 'bout the others. Are they amels. and anerys?

Cheers,

TC

taeniura Aug 22, 2004 02:52 PM

hi glenn,

I haven't got the Anerythristic ones this year but next year I can have a single male or a couple Hets. I also have had some contact with Wai but the snakes become to expensive when shipped to europe. So I did not buy any snakes with him. I heard he is back to asia (don't know the country).

succes with your snakes,

greetings,
mark
