If this is the one... It's the most frequently seen snake in South Korea. We call it "flower snake or Yu-Hyul-Mog-Ee"
This is rear-fanged snake, but people consider it harmless.
:I recently was brought a snake that was cought in rural South Korea. I couldn't identify much about the snake other than it was a colubrid. It was aproximately 15 inches long and had an overall olive drab to slightly greener color. It had broken bands along its body with bright orange spots on either side inbetween every set of bands. It was a really interesting snake and was extremely placid. Any help in identify this snake would be greatly appreciated. Thank you Todd Becker
