I've only found one of these
snakes, and from what I've read, I was lucky to see even that
one! "Subocs," as they're called, have a very
limited range and habitat preference. They're nocturnal and
spend much of their lives out of sight in burrows or rock
crevices. I came upon this one on a July night in 2002 near
Del Rio. I think it was a male, about 4 feet long. |

This is an only-slightly-better
shot which helps illustrate the pattern. The snake's base
color was a straw yellow, and the pattern was dark brown stripes
with connecting saddles of lighter brown and gray. The
pictures here are stills from my video camera, which helps to
explain the poor quality--I found this snake a month before I
bought my digital camera! |
