just thought id post pics of the eyes on my new normal striped corn. No round pupil, a vertical slit like pythons etc. never seen anything like it on a corn before.

That is odd.

You sure it's not some sort of hybrid? Can't see how else eyes like that would show up on a corn .....
 
thats very wierd...cool, but wierd. I can't help you on this one. Looks almost like a house snake. It may just be a thing with the light...everytime you notice it and go into better light to check it out, his pupils contract...????

Can you post some other pics too though? I'd like to see a full body pic on this guy.
 
THAT IS SOOOOO COOL!!!!!!

I want one like that!!!

Does he react normally to visual stimulation? Does the pupil expand and contract like a cats eye or is it fixed?

I'd love to see if that gets passed on...looks kinda creepy but very cool!!!!!
 
Hey I'm only just across the water in Sweden (well only 100kms or so!!) so if you end up reproducing that trait, I'd love to buy some hatchlings from you.

nah, i know the guy who bred it and it comes from a long line of corns.

its very weird, but looks awesome.

Even wierder!

You're right though ... it looks well smart.

Hmmmm ..... you're in Yorkshire ... only a couple of hours drive south of me .... has he got any more for sale ???

:cool:
 
Makes you wonder just how little difference there is between pythons and corns... If a small mutation is enough to give a cornsnake a different type of eye, and a small mutation is enough to give a corn the head-shape and eye-size of a python (as I've seen in atleast one other thread)... I wonder just how much difference there really is, genetically.

If both sets of traits turn out to be heritable... it'd be quite possible to breed a line of python-style cornsnakes.

Admittedly most of the cornsnake genes we've discovered so far have been pattern-related or color-related, but ones that affect physical form are just as interesting. I now am wondering just how many cornsnake physical abormalities were frozen or fed off as 'defects' alongside the kinked or truely deformed snakes...

(I can imagine the heated debates people are going to have over whether physically different cornsnakes should be bred or euthanized.)

Interesting times...

heres a photo of her full body, although it has come out a bit dull you will get a good idea.

she still acts as though there is normal vision from the eyes.

Hmm.. any pics of the parents or grandparents? And any breeding plans? Her coloring is a little interesting too (probily just the lighting).. could you get a closeup of her head pattern??
 
Maybe an unwelcome reply at this topic, but isn't that an Elaphe O. Quadrivittata? Or maybe a Rossaleni in shed but i think the first..

even if it were a rat snake of whatever type it still doesn't explain the eyes...
at least no rat snake I have ever seen had eyes like that...

although I do think that somewhere along the line there has been a nut in the mix...
maybe some sort of wild caught hybrid?

one really off the wall question but what do it's teeth look like and (I think someone asked earlier) do you have a photo of the head pattern that shows the scale design of the head?
 
cheers all for comments.

heres a head photo, will see if this sheds any light on it but the scale patterns look corn like to me, which id expect knowing where it was bred from.

That is very very cool! Has this individual been bred yet? It would be awesome if this turned out to be easily reproducible. :D
 
dont think its been bred so far, i will be the first.....

cant wait to work on trying to prove it to be a genetic mutation
 
I guess 2005 will go down in Corn Snake History as the year that everything was believed to be a hybrid, LOL.

If this is a result of hybridization, then the species it was hybridized with would have to have eyes like that. What species can produce fertile hybrids with corns, and has eyes like that? There's one gene (in fruit flies, and mice, and presumably it exists in everything in between those two) that when mutated causes the resulting animal to not form any eyes. This doesn't mean that mice are the result of hybridization with fruit flies. :rolleyes:

I don't see why it would be hard to believe that a single gene can make such a difference. A pupil like that could result from something as simple as the muscles at the top/bottom of the pupil being permanently contracted, or not present, or whatever... I'm sure there would be 100 other simple ways for such a thing to happen.

Here is a description of a genetic abnormality in humans that causes vertical pupils:
Cat eye syndrome: A constitutional chromosome abnormality (one that is present at or before birth) with multiple malformations characterized by the combination of a cat-like slit of the iris of the eye (vertical coloboma) and no anal opening (anal atresia). Frequently there are also down slanting eye slits (palpebral fissures), tissue tags or pits just in front of the ears, heart malformations and kidney anomalies.

There is usually normal or near-normal development with the cat eye syndrome, unlike the situation with many other constitutional chromosome abnormalities, and intelligence may be normal or near-normal in cat eye syndrome.

The syndrome is due to the presence of an extra small chromosome that is smaller than chromosome 21, the smallest chromosome in humans. This extra abnormal chromosome is derived from chromosome 22. (In technical terms, this chromosome represents an inversion and duplication of chromosome band 22q11p.)

(Are we going to wonder if these humans were hybridized with cats? LOL)
 
cool

im pretty sure its not an hybrid anyway as i know its source etc etc.

will just have to wait and see what happens......how stunning would an amel be with red pupil in this form?

the list goes on
 
The more I see it, the more I like it!

I'm on the lookout for something new at the moment. If there are any more of these available, I'm very interested in taking a trip down the A1 if it's within my price range.

Could you drop me a PM and let me know?

Heres hoping!

:)
 
i'm not saying it's a hybrid, because i believe that there very easily could be a gene mutation that could cause that, but Mexican Night Snakes have eyes that look alot like that. i'm not sure if you could breed a corn to a mexican night or not.

that's sure a neat looking corn though.
