I have two brothers that know a lot about critters. They have done much studying, excavating, sifting through the dirt looking for bones. And written these scientific papers.
I know a cow from a horse, and I can tell the front end from the back end. So when I ran across references to the whiptail lizard on the internet, I thought that looked interesting, and maybe I should mention it here. Just in case they have not run across them. They seem to have some odd characteristics, such as being able to reproduce without males, in some cases. Or lack of a male of a given species (if it can be called that).

Anyway, I thought it interesting. But I guess I don’t have much more to say about them. I knew this site needed something besides unintelligible computerese, so this is a tiny bit of that.
