That's a nice lookin' tigrinus! Is that typical color and pattern for Korea? Here are some Rhabdophis tigrinus from Japan:



What species of herps do you find regularly throughout Korea? From what I understand, it is a relatively poorly surveyed area?
I'd love to see some ratsnake and habitat pics from the field!
In regard to the link that John provided, the snake certainly looks like the same species as the link I pasted. Definitely not Gloydius sp..
