Hypomelanistic A.texanum?

Our ponds fill up with A.texanum larvae, and I noticed & netted this individual the other day. Would it be right to think it's hypomelanistic? Wild type for comparison.

Also, another larvae at the all-you-can-eat daphnia buffet!

All my other smallmouth have morphed ages ago, but not this one yet, for some reason. If it stays neotenic, I'll just keep it like a miniature axolotl I suppose ?.

Do neoteny and hypomelanism go together?

Hello,

melanophores expression in phenotype is partially connected with hormones in some animals. There is a possibility that the mutation goes for some kind of hormone deficiency.

Best wishes :)
Nice find by the way!

Good to know - thanks! I have the tank propped at an angle, and he/she has begun to venture shallow half out of water, but the gills haven't shrunk accordingly like the others. I really kind of hope it stays neotenic!

for any interested, gills never went away, and her fins "re-webbed" (if that's a word). So, I have her in a 2.5gal tank worth in 3 inches of fresh spring water, as she's thriving. Ese tually, she's a miniature hypo axolotl. Eats mosquito larvae and small earthworm bits. About 2.5 inches long.

Moved to a custom long I built from glass display shelves. End is walled off (rocks hot glued) which allows for filtration with minimal current. Next year I'll be looking very hard for more.

Update - still going strong, no morphing... hunt for more begins in a month or so!
NAGs?

I wonder if these are similar to NAGs. They are infertile as it's been described similar to down syndrome.
I'm not sure if I'm allowed to link to Strohl's Herptiles Facebook, but here's his write up:

Identifying characteristics of a NAG:
1. Melanophores are visible in the eyes, with few scattered over the face, back and gill stalks, except...
2. Melanophores are abundant and clustered into spots on the tail, with the greatest density at the tip and margins of the caudal fin.
3. Iridophores are abundant in the eyes, gill stalks, and legs. Few, if any, are on the body. They are so abundant in the eye that only the pupil of the eye appears dark.
The second point matches what you have with yours with the melanophores being on the tail.

    I've advertised my CB alpine newts for sale UK but no offers so far. I'm looking for a carer/enthusiast so I put a price to deter people who might not be serious about the responsibilities of the undertaking but how do I find a genuine enthusiast who will take over care? I'm not looking for money, just a good home for the newts.

    Hey guys, its way too hot where I live right now. Temperatures 40 degree celcius outside, making it like 30 degrees inside. Ive got ice packs on my yellow spotted salamanders hidey rock, he acts like he hates it though. Am I keeping him too cold? I think my temp gauge might be messed up, or at least in the wrong spot. I put the tank temp gauge in the top left corner of his large tank, where it says its 80 degrees fahrenheit, which I am aware is too hot, which is what makes me put the ice packs on his rock at the bottom of the cage, but the bottom of his cage feels a lot cooler tha 80 degrees. Should I move my temp gauge down to the bottom corner where he hangs out the most? Should I get a soil temperature probe so I can tell what temperature the soil that hes laying on is?

  • FragileCorpse:
    Because his soil is certainly not 80 degrees fahrenheit, and I dont want to freeze the poor bugger with ice packs if he really doesnt need them. Hes been doing fine, but Im just so stressed because I cant get ANy information on how to handle this little guy. Theyre illegal to keep without a permit, but this one would not have survived without my intervention. So I cant call and ask anyone for help. If theres a betetr site than this one, I sure havent found it. But I never get any replies here. We are all just asking questions and getting none answered basically. Its really frustrating as I just want to help this little dude be happy and healthy. All I can get him to eat is potato bugs as well. I cant find anything else that he will eat. Is that even okay? :/ hes been eating strictly those since may first.

    I'm afraid this is the largest and most active community for this kind of information, probably on the entire internet. That said, we are still small overall. We can't help you all of the time. We do offer you support and have answered your questions in the past so I feel it's very impolite to lose patience with us.

    Third of all, assuming thats the case, no one seems to want to face the reality that these animals come from climates and microenvironments where they need to be kept cool. If you can't hack, then release it where you pulled it from.

    The ONLY reason I spent 500 dollars on this thing was to keep him alive. thats IT. He was completely dry with cracked skin and couldnt walk and I nursed him back to health. Now I should just throw him outside on the hard baked ground where I found him? in my driveway? Really dude?

    I am losing patienc ebecause I care. Because I cant get any answers in any length of time that will actually benefit him.

    I am very sure he was just trying to pass by, because he certainly cant dig ANYWHERE in the soil ANYWHERE near where I live. So I cannot just release him in 40 degree celcius on the super hard baked ground where theres no shelter and no food and now ater to be seen for miles. I dont see how that wioll help him at all.
