Can anyone tell me what these guys are

Sorry for the phone quality picture, but can anyone give me an idea as to what those little clear guys in the substrate are?

They appear to be mites.

I'm gonna say one of the 50,000 species of soil mites...*shrugs*
Most are harmless to tarantula's, but bad for plants! However, I've heard of a few species that are predatory, so if you pulled them out of a tarantula enclosure, I'd dump it just for peace of mind.
