Species with neotenic members

[AU SalamanderRG]

Any other species outside the Ambystoma Mexicanum and Ambystoma Tigrinum with neotenic species members?

Of course there are. There are plenty actually. In europe, at least M.alpestris, L.vulgaris, L.helveticus and T.pygmaeus do have neotenic individuals. There´s also the completely neotenic Olm.
In Asia you have Cryptobranchids...
In america, there´s also cryptobranchids, sirenids, proteids.. which are all neotenic. And you have some plethodontids that have neotenic populations too.

Also Dicamptodon.

Since this post is in the Ambystomid salamander sub-forum, I thought he meant only Ambystomids which were neotenic. Here is a list. http://en.wikipedia.org/wiki/Ambystoma#Species T is terrestrial V is terrestrial and neotenic and N is neotenic.

I have an ambystoma barbouri that hasnt morphed in 6 months. it might be neotonic, paedomorphic or whatever you want to call it.

The Tennessee Cave Salamander (Gyrinophilus palleucus) is my favorite. I'm very lucky to get to see these neat salamanders frequently. But since they are threatened and only viewable to those who venture deep into caves, few people will ever get to see them.

I've had a heck of a time trying to get some good photos of them, but this is the best I've got so far.

That's a beautiful Salamander.

Ambystoma talpoideum and A. gracile are facultatively neotenic, like tigers.

Ambystoma Gracile.
