They can bite if you pick them up and show them to someone. I guess my grip may have been too rough or perhaps the glass lizard was in a hurry to grab lunch.
Edit to add:
I forgot to say, the lizard was like a bulldog; he (or she) didn't want to let go.
For those who never saw an Eastern Glass Lizard and since I was not able to take a photo that day, here is a link.
