"Wild type" is an apt description. But I remember an interesting thread on the KS law forum several years ago about semantics and our hobby / industry. Somebody said that we should be cognizant of how our terms appear to the non herpers in the general population. Because we are now raising what are, or are becoming, domestic pets rather than wild animals, it will help us raise awareness of that fact if we start using more terms common with domestic animals (pets or livestock) rather than those used with wildlife.
True, it is a double edged sword. On one hand, we bemoan the fact that new herpers have often become "deli cup herpers" without much knowledge of the wild origins and natural history of their corns, ball pythons, or other herp pets. But on the other hand, dog, cat, and rabbit owners don't need to know a lot about the natural history of their pets' ancestors to become good pet owners of their species. We herpers are in the middle, with not quite domestic animals, but not truly wild pets, either (at least in the case of corns and a few other selectively bred herps). I think it is still important for all herp keepers to learn as much as possible about the natural history of various herps, and to appreciate nature in general. Yet from a legal perspective, we would be better off if the public considers us a domestic pet keepers rather than exotic keepers. An interesting conundrum.
So that is a long winded explanation of why I like to avoid the term "wild type" in our (sort of) domesticated corns.
