What a cute little freak. Do you think the two are related? That is the leucistism causing the neoteny?

The two (leucism and neoteny) are often related in other species, such as Mesotriton (Ichtyosaura?) alpestris.

they are also both recessive and show up more often in inbred populations.

Francesco,
Do you think you could induce it to morph with reduced water level and increased temperature?

Hi Travis
salamandra larvae can't tollerate high temps (above 20-22°C) so I would probably kill it if I increased temps of the water. If it gets to adult size without morphing though I'm going to try giving it some tyroxine. Infact once it morphs it will be able to breed and who knows..maybe one day I'll have a leucistic strain of salamandras.

Francesco,
I know that salamandra larva can't tolerate high temps...I was thinking if you were keeping it in the 13-15 range...that increasing it to 20-22 might trigger it to morph. It may just be me, but I think it would be healthier to morph at this size than adult....if it morphed at adult size it might have a harder time adapting to land...feeding, etc.
I would love to see it as a terrestrial adult..it would be stunning. Please keep me posted on the progress.

The caudal fin appears to have reduced slightly and it's lost much of it's larval spots. The colouring you'd expect on a new morph is starting to appear. I wonder what will happen...
Thanks for posting an update - show us more in a few months.

I think your idea is a little misguided, bobberly. It's not the keeper's choice whether the animal remains neotenic. It does, or it doesn't, according to its own biological program, and the keeper has to provide the habitat to accommodate it, whatever it does.

Francesco passed away a few years ago. I don't know what happened to his collection. Perhaps one of the European keepers has more information on that.

Shane douglas:with axolotls would I basically have to keep buying and buying new axolotls to prevent inbred breeding which costs a lot of money??+1

Thorninmyside:Not necessarily but if you’re wanting to continue to grow your breeding capacity then yes. Breeding axolotls isn’t a cheap hobby nor is it a get rich quick scheme. It costs a lot of money and time and deditcation+1

Clareclare:Would Chinese fire belly newts be more or less inclined towards an aquatic eft set up versus Japanese . I'm raising them and have abandoned the terrarium at about 5 months old and switched to the aquatic setups you describe. I'm wondering if I could do this as soon as they morph?+1
