Help urgently needed: My tarantula refuses to lay eggs

[saintevil]

My Pamphoebetus fortis female was mated and we kept the temps perfect and everything. She created a thick mat of webbing and for a few days we thought she laid eggs. We left her alone for 10 days and just checked up on her to see if they are doing fine.
We discovered the egg sac abandoned. When we checked up on her, the egg sac had no traces of eggs inside and she still had a very fat abdomen. Shining the light on her abdomen, we could see the eggs inside. She didn't lay any eggs yet and she is refusing to do so. Now she looks half dead and is hardly moving.

No, we didn't bother her a lot or tampered around her enclosure, she was seperated and left in a dark environment away from disturbances.
No we didn't check up on her daily, once we saw the mat, we left her alone for a few days before checking up.
Today was the first time in 10 days that we checked up on her.

She looks impacted and she is extremely unresponsive. She had access to fresh water the whole time. Any advice would be greatly appreciated.

Photos attached. The last one we are trying to give her water

Interesting. If the condition is found to be terminal, you really want the eggs, and if you have the stomach for it, perhaps you could try to do a Tarantula C-section. Not sure its ever been done though, or the viability of the eggs now. But I know people have done some wild things to keep eggs alive.

Nice size T - this is a bummer

I have zero experience with this, but if she is unresponsive, have you tried gentle pressure towards the exit while using a wet qtip at the flap? Try to help her expel them?

That is a egg-bound female. It can happen but very rarely. It's usually more common with smaller females that are gravid from what I've seen in-person. Looking at the pictures, it appears to be quite a decent size mature female. In your situation, it was just a case of bad luck.

We tried that with no success

I’m so sorry, man. :.-(

Thank you for the feedback. It is literally the first female we bred and we were so cautious with her and the temps. She passed away this morning. We removed the eggs and a few of them appear fertilised.

I'm confused and seriously thinking I might just take up knitting and leave spider's alone because I've been under the impression that when laying an egg sack,the eggs come out more like a soup and then develop into what is an actual egg?

So much of this post has me confused.

One of the cool things about spiders is that there's always something new to learn. One of the lame things about knitting is that it's lame.

Please explain to me how this happens then?
How does a spider go from laying a sack and not depositing any liquid and then said liquid turning into eggs while in her abdomen?

Oh lol I've only bred a few times, I'm not a pro. Was just being goofy about the knitting stuff.

It took me about ten minutes to stop laughing about what I'm going to say but, with some practice I may be able to hook you up with some 100% pure organic polyester alpaca socks or mittens. So keep me in mind.

I dont know if this is true but i always assumed that the eggs are produced first and that the liquid is basically an excretion only produced when eggs are going to be layed, or perhaps multible different excretions that fullfill different functions.

For one i always assumed the fertilisation happens during the egglaying, where the male sperm is introduced into said liquid.

Perhaps it is produced in the spermathecae or even the assessory glands, do females have these, i can't remember?

It is also usually produced before the eggs are layed. So perhsps it is essentially a sperm and nutrient soup? It could also lubricate the eggs so they don't damage each other while they are still growing into little embrios.

Anyway it will be interesting if there are any fertile eggs as that would indicate i am wrong and fertilization happens internally.

I guess i will have to leaf through 'biology of spiders' again to see if i have been talking rubbish.

@cold blood

not sure what you want from me, I dont have a clue what is actually being asked.

OP appears to want to know the process of how Tarantulas produce, lay, and silk wrap their egg sacs when they produce them. I would rather someone with knowledge and experience in breeding reply to that inquiry.

@Mike Withrow. Nature is nature and sometimes it goes awry even with our best intentions.

I mean, you can't do anything. If it doesn't want to lay the sac, it's not gonna lay. You can't force them to do it.

Yeah it’s really sad the ops t died gravI’d !???

"The eggs are expelled from the epigastric furrow in a viscous liquid that dries when it comes into contact with air, cementing the eggs together. This is done onto a basal disc of silk covered in flocculent (fluffy) silk that she constructed beforehand and this is in turn attached to vegetation or included in her web. It is only during the egg-laying process that the eggs come into contact with the male sperm and are fertilized. The eggs are then covered with more flocculent silk that traps air that insulates the eggs and protects them from dehydration and predators such as ants"

The eggs absolutely come out fully formed as eggs. They don't magically form from fluid. That would be weird and impossible. The eggs form inside the mother and are then deposited as an egg which is then surrounded by accessory fluids. They are not deposited as a liquid that then magically "forms" egg.
