T. s. tetrataenia or T. s. infernalis???

[prattypus]

I have to admit I never thought of it the way stefan puts it. I always thought of hybrids (and F.Y.I., hybrid snakes are usually fertile, they aren't mules, you know) as crossing different thamnophis species. Intergrades are same species, different subspecies. I don't care if the subspecies breeding is ONLY a result of human interference that never occurs in nature. I will still call it an intergrade.

Obviously, a T.s concinnus would never breed with a flame eastern (t.s sirtalis) in nature, but if it happened in captivity, I still wouldn't call that a hybrid. Hey! who's up for trying that?

That's what I thought. Not too many people.

Wait- garter snakes aren't mammals? I know you mean well, but sometimes you come off quite arrogant. And are mules the only hybrids that are sterile? I thought Ligers were too?
