Not entirely sure exactly what specied this is or how to tell the sex. I believe it is a bibron, thick toed gecko. I got it from where I work but they have it listed as a white spot, but I don't think thats correct. Anyhow I have been taking it out each day at work and it is getting tamer, now Im attached so I bought it. I now have it so you can let it sit flat on your hand and pet it. Its pretty cute, here it is.
