My 1 year old male tegu, has within the past month become extremely territorial and easily agitated (guberty I suppose), but also has come into the habit of biting hands, constantly, it has gotten to the point where he bites them every single time he sees them, he does not attempt to bite any other part of the body, He is fed inside his enclosure, on a plate, before he wakes up, so he should not be associating my hands with food at all, his basking spots are 125, 120, and 115, ambient temp of 80, 70% humidity, full UVB, and he is in an 8x4x6 enclosure.
