Did not really know where to put this so I decided to put it here. Just want to ask a question? Does any one know of a complete list of the "Inducible obligate" neotenic species. I know of Ambystoma mexicanum (of course) but there are other species of ION Ambystoma in Mexico I believe. Also know of Eurycea nana, E. neotenes, E. rathbuni, E. troglodytes, E. tynerensis, Gyrinophilus palleucus and Haideotriton wallacei but not sure if there are other ION Plethodontidae.
