[Cazador]

Many people call that red one the most beautiful garter snake in the world. It's a San Francisco garter snake (Thamnophis sirtalis tetrataenia). It's on both California's endangered species list and the Federal endangered species list. You can't even pick one up in the wild for a picture without committing a felony (literally). They are, however, legal to own and sell outside of the U.S. You just can't transport one out of the U.S. without special permits that only legitimate zoos, etc. can acquire. Many years back a few foreign zoos thinned out their inventory of tetrataenias, which gave rise to their appearance in the pet trade industry.
