With permission from my friend Tina (callina) I have some interesting photos to post. One of her axolotls has laid a cluth of eggs in which all of the eggs are elongated. Has anyone ever seen anything like this before? The embryos are still very young; we are all waiting to see how the develop. I will be glad to update as Tina makes new photos.

Hi !

The jelly coat is very, very elongated, but the egg per se looks normal.
Is it her first spawning ?

I've never seen such a phenomenon.
I once had a female laying, for her first spawning, perfectly round eggs, but with a too hard jelly, so that the embryos couldn't elongate normally and all hatched distorted.
The year after, the second spawning was normal.

The eggs, i.e. the inner sac, are also elongated. The embryos are apparently normal and developing as usual (pics below). Note that they are all growing along the length of the egg "tube", none crosswise. This is not the mother's first clutch; it is the first clutch that looks like this, though.

Anyway, the embryos seem absolutely normal in your case.
Good news.

So, Tina is being too lazy today to write in English, so I will update before she knocks me on the head.

One larva has tuned crossways in the egg and got his egg rounder. Two other larvae that are active twitchers have got their eggs rounded out a bit, too, but the rest are all still misshapen.

No new photos at this time.

Has nobody seen this before?

I havn't seen the elongated egg sac before. I have noticed that young axolotls seem to throw some odd eggs that have low viability. If the larvae turn out good I wouldn't give the sac a second thought. If you have problems with the larvae I would take a second look at the health of the male and female.

Please keep us updated.

Sorry I don't have the answer for you, but thanks for asking the question; I may run into that issue.

Hi,

thank you for your replies.

I think this will be the last pictures of the eggs; the larvae are going to hatch in a few days.
One egg didn´t develop and you can see it is as small as before. All eggs with larvae inside became rounder.

That's good to hear. In my ignorance, (I'm not an experienced breeder), I was beginning to wonder if they'd have trouble wriggling out without the tension of being curled up in a round casing.

omg - a bad typo! :eek:

Surely it´s not 11cm, but 11 mm! :D Otherwise it would be a monster larva. ;)

All larvae hatched yesterday and they are doing fine. They are between 11 and 12 mm in size. No one had any problems to leave the egg.

I will take some photos in the afternoon, when my camera has full power (accus/battery).

so, here are the promised pics :D

The color is very unusual to me. It´s a cross between leucistic and golden albino and the pigmentation is wild. They are well developed and their behavior is quite normal, like all the other newly hatched larvae do.:D

Tomorrow they will get their first meal - brine shrimps - the hatchery is going on.
