Question: Regeneration experience/knowledge

[paris]

I am having to repost this because I put it in the wrong section before...

Hello

I am posting here because this is a general question for the members, the research community is limited on the species they typically use for research.

I am proposing for my PhD regeneration research and am looking for amphibians that break the rules. specifically I am looking for salamanders that cannot regenerate or adult (post tail) frogs/toads that can. I know of a few salamanders that cannot regenerate lenses or a few organs, but want to know from the members if they have knowledge or experience with those that are outliers.
I don't believe there are any salamander species that cannot regenerate limbs, but if you know of such please let me know. my goal is to hopefully find the nearest relative to salamanders who have lost the ability to regenerate and look at their immune system differences.

I suspect that Neurergus don't regenerate limbs, or at least not as well. But this is based on limited anecdotes. I'm certainly interested in any observations from anyone who has observed regeneration in a Neurergus.

it is known that ah the organism ages the regeneration process is slowed, in your observations were they incomplete/slow regeneration or absolutly no regeneration? any idea of age?

 

[paris]

redesign the question?

perhaps i should post this the other way round -make it easier...in which salamander species have you seen regrowth-esp of eyes & parts of heads. AND in which adult anuran species have you NOT seen likewise?

--also, anyone going to sound in for the caecilians? I know they have no limbs to regrow but what about their other parts?

I've seen limb/tail regeneration in Triturus, Lissotriton, Ichthyosaura/Mesotriton, and Cynops/Hypselotriton orientalis.

The only thing close to head/eye regeneration that I've seen is a Lissotriton montandoni that developed a cloudy eye, and seems to have healed completely.

Some salamandrids and plethodontids exhibit tail autotomy, don't they? Presumably all of those have some capacity for regeneration...

I've seen tail regeneration in wild Plethodon cinereus where the tail was severed up near the cloaca, but obvious regeneration was occurring.

I've heard anecdotal evidence of a hellbender (cryptobranchid) completely regenerating an eye in captivity after a fishing hook went through it. This was from a biologist at a nature center, so I trust the story.
I love the research idea!
