Larry, all snakes have teeth. The rows of teeth in a Gray (or Black) Rat Snake will look like fangs. A Water Moccasin, or Cottonmouth, is a snake of swamps, and does not approach this size. Also, a Cottonmouth has a completely different pattern. Almost all snakes have a white inner lining of the mouth, making them look like a Cottonmouth when alarmed; the Black Rat Snake I caught Tuesday showed a white lining to the mouth while biting me three times (she was very frightened), plus, when looking in the Peterson's Guide, it doesn't look like Cottonmouths make it to Northern Alabama. Of course, people will call me a liar, and say they have seen "Water Moccasins", but these are simply Water Snakes, and are harmless.

Its an Eastern Garter Snake. They're harmless and nonvenomous.

It is indeed a Glass Lizard. Find a copy of Peterson's Guide to Reptiles and Amphibians of Eastern/Central North America, and look up the Glass Lizards. Looks to me like an Eastern. I have seen exactly one live one, and it was too fast for me. Called "Glass Snake" and "Joint Snake" due to the ease with which the tail breaks off, sometimes into several pieces. The "old husband's tale" goes that they will break apart at a blow, and reassemble themselves after the attacker leaves.

Well, now you all have me completely confused but yet totally facinated about snakes. I have read all 22 pages of postings on this forum and it seems that Rat Snakes are by far the most common backyard snakes (and maybe garter snakes which I was already familiar with). So how do you tell the difference between a Black Rat and a Gray Rat and why do you think this is a Black Rat and not an Intergrade Black/Gray. I also saw another snake the other day, about 4 feet long and just solid black, so I am assuming Black Rat Snake (no camera handy). So, although I'm interested in learning more, I don't think I am ready to try to catch one. I know that they have their proper place in our eco-system and I am happy to leave them be outside as long as they aren't dangerous to me or my little dog (my fish and frogs in my fishpond, however, may not be as lucky?) This looks like a very interesting hobby. We also had a snake a couple of years ago that everytime we saw him he would dive into the fishpond. I haven't seen him lately. So, if I see a snake in the yard, like the Rat Snake, is it more likely he lives here or more likely he's just passing through?
