I'm not sure what they are, but the head structure doesn't look right for them to be gargoyle geckos. Looking at pictures online of the Marbled Gecko, I would have to say they look pretty close to those.

I have to ask though, why did you get something if you didn't even know what it was? I'm not trying to be mean, but I really had to ask.

Also where did you get them from, is there any way you could ask the person you them from?
