Ambystoma jeffersonianum Hybrid?

Is s/he a hybrid? or no? She's approximately 7" long, but Mike G thinks her toes are too short to be a pure A. jeffersonianum. What do you think?

PS: they're not normally this fat. This was "Thanksgiving" cricket day.


PPS: Here's some other pics, just for John.

This is a heron of sorts that was just hanging out at the Wilhelma Zoo in Stuttgart, Germany

This is a Great Crested from Morg's yard.

Well you were talking about bird pictures in chat the other day, and I thought I'd throw in my two cents.

<font color="ff6000">I believe that is a hybrid of A. jeffersonianum x laterale. It has a jeffersonianum background set with a laterale spotting. Both have long toes, jeff's dorsal isn't usually very blue with specks, it stays downward of the body and belly. The lat's are often very DARK and smaller in total size.

Does the range have both?</font>

No locality data available (despite repeated requests). The other two (and the two that disappeared) are all fairly light, and the spotting is definately confined to the lower parts of the body. And I was assured that all were collected together from the same area (breeding pond, I assume). She's just slightly moreso spotted than the others. The picture hides it due to glare, but along the dorsal ridge is fairly devoid of speckling. It definately does taper off toward the top. Also, you can see her legs are heavily spotted, and how this also tapers off as you travel upward. Personally: I think she's too large to be a hybrid. Hybrids usually run more toward the laterale size than the jeffersonianum size. I think she's just unusually heavily spotted (similar to Tim's designer cynops of gold).

Lol, I'll take pics of the other two and post them all 3 together.

Hello Kaysie,
We each got a lavendar/gray-colored Axolotl from Jennifer and I see from the above photo that yours was also VERY lavendar like mine. What does it look like now? Has its color changed much lately? Does anyone know how common this coloration is?

Megan, its now extremely dark purple.

This coloration changes on a daily basis, lighter or darker. I couldn't tell you whether this is due to lighting or other things. This is about the darkest I've seen it. Also, the coloration is very smooth, not speckled like the others.

Kaysie,
I have found many salamanders in Michigan over the years that look very similar to that and have measured 6 to over 7 inches. They are usually located with laterale populations. I have always assumed they are lateral-jeff. hybrids, (of which I know there are several).

These were collected in Pennsylvania. I'll get that pic up tonight

As promised (if a little late) here are pics of all 3. The female in question is on the left.

Now I had some A. laterale for a brief period, and they were more heavily spotted than all 3 (5 at the time) of these. And were much smaller.

<font color="ff6000">I STILL go with my original answer of hybrid of A. jeffersonianum x laterale. Size and the background send me that way. Jeff's can reach 8" and lat's reach 5". Laterale are smaller, shorter-legged, narrower-snouted, and darker. I also remember something with jeff's tail being larger and more compressed then the lat. </font>

Mike agrees. Guess there will be no breeding here, unless someone wants some crossbreeds.

I would be interested in a few hybrid babies, in the spring if possible. I don't know how desirable they are for other people but I specifically want HB's.

After crossreferencing the data I have with Petrankas, I'm going to stick with the idea that these are Jeffersons of the pure-blood variety. According to Petrankas, none of the hybrids are found in Pennsylvania. You might sway me to JJL hybrids, but I'm sticking to my guns. Especially since the 3 of these look practically identical to the Jeffersons pics found in Petrankas. (Can you tell I just got my own copy of it? lol)

    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?
