Those certainly look interesting. I'm not very knowledgeable about Pachytritons, so I can't help you with species ID. I suppose it would take genetic analysis to see if it is a non-labiatum species for sure. Are the bellies really that yellow or is that an unexpected photographic efect?

Aaron,

these are truly odd things. I am not sure , but is one of the animals having cornifed toes (or is it just dirt ?).

They come close to the animals that I had once acqiured , many years ago and which were light camelbrown with the underside like an oystershell. However my animals have a far rounder tail then yours.

\image {Pachytriton brown}

The recognition of P. brevipes still is having black dots on the undersite of the belly,which yours are not having. So they are not P. brevipes.

I'm also surpised with the enbedded eyes of those bluky large animals and their very very large head ( which is also very wide). But perhaps they will still need to take some weight ( I guess you just acqiured them ?). Also they can still change coloration ( I once had a faint brown one turning into blue-black when placed on a darker soil)

I would be interested to see some closups of the head of that bulky one.

Hi Aaron,

did the color change in the mean time?

I'd guess that these come close to Pachytriton sp.B (no distinct black spots, long toes, general coloration) - cp. http://www.dght.de/ag/urodela/arten/taxonomie_biologie_pachytriton.php3

I wouldn't place too much emphasis on differences in tail morphology - specimens from commercial sources have usually been stressed quite a bit and/or were kept at rather high temperatures. IME this results in relatively narrow tail crests which will revert back to the usual form seen on Henk's pic once the specimens have acclimatized themselves to the new environment.

However, since there are already undescribed taxa around there is always the possibility that these newts turn out to be another "new beast". ;o)

Maybe you could give it another try to get decent pics from the belly and close-ups? Please let us know when the males develop their iridescent spots along the tail!

Best wishes,
kai

    I currently have a 3 year old axolotl, he hasn't been eating for the past couple of weeks and has lost a lot of weight. Hedwig usually eats bloodworms and earthworms just fine but now he won't even stud it. I've done a water change to make his nitrate lower and his water is at a good temperature

    Hey guys I was wondering if my axolotl looks fine to you he/she (still don’t know) I’d activate and eating as usual but I did notice veins in the tail area.. let me know what you guys think! Also if anyone could tell if it’s a boy or girl that would be great! (Zolo was eating a worm and pretty sure the worm pooped XD)
