Hello,,

Just read in :
Handbook of Genetics, Vol. 4 : Vertebrates of Genetic Interest, par Robert C., King, 1975, page 15 :

"...a color variation has been found in the F2 of a pair of this species (Pleurodeles waltl) captured in the wild (La Croix and Capuron, 1970). This mutant m ("mélanique") is comparable to the melanoid mutant in the axolotl in having an increased number of melanophores and in lacking iridophores."

Has anyone seen or heard about melanoid Pleurodeles waltl ? (Idon't have any)

The absence of answer is an information in itself.
I asked the same question the a french forum Urodeles but with no more success.

Thanks for this reply.
Do you mean specimen living in very dark aquatic environments can be very dark without a special genetic background? (why not)

Yes, color depends largely turbidity and color of water.
Specimens living in pools of irrigation or irrigation ponds are usually quite dark, with many stains.
Specimens living in ponds with clear substrate or white turbidity are clear and spotless

Thank you for these observations.
We suspect the same phenomenon with our Tylototriton verrucosus (Darjeeling) captive strain.

    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

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)
