They are mostly the same, but as you look into them, you'll find some are much nicer than others. Now, there is a T positive line in Germany, and some of us have what's been termed "hypo" dumerils, but these aren't available in any numbers yet. There are some "striped/reduced pattern" animals, but it seems most of these are males and it doesn't seem to pass on in any predictable way. And they all have a white patch under the throat, which is another common question once people get a new Dumerils or happen to finally notice it. Hope that helps.
