I was in my backyard, when I saw a lizard crawling around. I like catching things like that, so I reached down and picked it up. Then it started squirming around, and it bit me! It left a mark, and it bled a little bit. I just wanted to know if any of you knew whether or not it's poisonous. Here is what it looked like: It was a grayish black colored lizard, with two vertical white stripes down either side of it's back, little back polka-dots inside the lines, black eyes, and small blue horizontal stripes down it's spine.
