...Snakes do. Not just two, as someone had mentioned. Subocs have 40 and Corns have 36. Heck, even the only congeneric to TPRSs, Bogertophis rosaliae, has a different karyotype than its closest relative (B. rosaliae has 38 chromosomes). To my knowledge, there has never been a hybrid Suboc.

One of the reasons you can't use ex-situ conservation techniques to breed intrageneric (Castor) Canadian and European beavers, for example, is because they have a different chromosome count. And I'm sure, at this point, there have been a few people who have tried to breed subocs with other snakes and tried in vain.

I've been asked to breed TPRSs with Bajas (not sure that I ever will or even want to)...I think, if Subocs have ANY chance to hybridize, it'd only be with Bajas. Bajas are the only other colubrid with lorilabial or subocular scales.
