I was just curious if my little "majora" has a little genetic defect that led to 2 gills on one side are if one was bitten off before i got her/him. It does not look like there is a stump where a gill used to be. what do you think?

I would have to agree, if it had been bitten off I assume there would still be a major artery leading to the place it was. As there doesn't seem to be one I'd say genetic. (somewhere else on the forum I remember seeing an axie with 4 gills per side due to genetics)
 
Thanks, Thats what i was thinking! kinda like it!
 
I'd agree and say genetics.

What a beautiful Asymmetric axie!
 
It does not look naturaly, but it looks indeed like a genetic disorder.
 
It doesn't look bitten to me. As a geneticist, though, I have to point out there's a third option. Almost every organism has some small anomalies that aren't based on the genome, but on which cells proliferated, lived, or died during development and growth, which is somewhat random. The prime example is the domestic cat's spots -- the general extent of the spotting is genetically determined, but precisely where the spots wind up is different even in genetically identical animals. (One major exception is the worm Caenorhabditis elegans, where every single animal has the same number of the same cells. Whoa.) So unless Majora has two gill stalks on both sides, which would be much more likely to be genetic, my guess is random developmental weirdness.

And I love the name! Maybe the next one can be Zora?

Thanks for the interesting information! Majora does have a tank mate named Zora (a wildtype)
 
Have you named these from The Legend Of Zelda series out of interest? If so I love it! :lol:
 
Playing the Skyward Sword right now..

I have a larval tiger sal who had one gill branch bitten off by a tank mate, it's body responded by building a super gill where the injury was, this gill branch is longer and thicker than any of the others by far. It's kind of cool.

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

    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

    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?
