My daughter found this out in the open on our back patio, she asked me why that worm was moving so weird. I picked it up and realized it was a blind snake. After the fact I reviewed the details with Brad H. from museum and he believes this is not the native species based on the very dark color and could be a range extension from invasive population in Chula Vista. I wish I would have kept the specimen for scale counts but I may have some better pics on my camera, will look and post if I find any.
