that's pretty interesting but not very shocking. i always suspected that japanese rat snakes could breed with american rats because they look and act so similarly.

i would be really shocked if someone crossed any of the beauty snakes with an american rat snake. i've tried it but never even saw an attempt to copulate.(corn x cave dweller)

i never really understood all that. how can they ever agree on the species name if they can't even define what a species is?

this might not be the place to ask, but does anybody have a clear cut answer to how "they" draw the line between two species?

"There are many definitions of what kind of unit a species is (or should be). A common definition is that of a group of organisms capable of interbreeding and producing fertile offspring, and separated from other such groups with which interbreeding does not (normally) happen. Other definitions may focus on similarity of DNA or morphology. Some species are further subdivided into subspecies, and here also there is no close agreement on the criteria to be used." - wiki

If you look at my post after the post with the japanses x corn theres a picture of a greenish rat snake x blue beauty.

i never heard/saw that before! it's awesome, what do you know about it, if anything? ...like what was the father, how many fertile eggs, how many duds, WHERE CAN I BUY ONE$$$ just kidding, i would love one but i have other priorities.

I believe both of these crosses were done in Europe. I don't know much about the greenish x beauty and its been awhile since I talked to the person with the corn x japenese rat. From what I understand though this cross has been done several times with good results and I know one account of a male breeding back to a corn snake and producing offspring.
