And at worst, it is merely a curiousity, which is why people post pictures of things that just don't look right I just fail to understand why there's so much resistance to identifying "specimen x" as a hybrid maintaing both sets of parent species characteristics instead of a regional variant of a species.
Eek! Not Hurlbert! Aside from that, sunfish hybrids are certainly curiosities and often happen because of human activities, like the dreaded greengill. Certainly sometimes shiners don't look right either; my skepticism (polite, I hope) is triggered when they're identified as hybrids when, frankly, who knows? I'm not sure I've ever knowingly seen a hybrid cyprinid in the mid-South, or even a hybrid lepomid. That could be my prejudice. I'm working the null hypothesis of "hybrids are much the exception".
Maybe my next band will be Hybrid Cyprinid?
