1)---Yep, I know
2)---acting like what? someone who wants an answer and not opinion?
3)---No, I did not ask for an opinion. I asked "What's the physical difference" between a "corn" and a "rat" snake. I asked for a fact not an opinion.
4)---The same research all these other people have suggested I do, "google" and the like.
5)--- I did not fail to grasp Genus, specie, and sub-specie....as a matter of fact I have a firm grasp of them. as I said before I KNOW THEY ARE OF THE SAME GENUS.......and from what I can tell, and from what I gather from "researching" it a corn snake is just a fancy way of saying rat snake. I am seeing a little bit of a difference in the head from one snake to another. I have "corn snakes" and "rat snakes" but I have never been able to tell the difference between the two when it comes to all the morphs. I know what a black rat looks like and I know what a yellow rat looks like, but ......you what never mind
like I said before thank you for giving a real answer.
