!!! Octopus mercatoris eggs !!!! (Help...)

We got an adult O. mercatoris on 12/22/07 - our anniversary gift to ourselves - and she has been eating really well until the last several days, has ignored a nice emerald crab for 3 nights running, and tonight we finally decided to have a look under the rock, fearing the worst that she might be dead (she had blocked off the entrances where we usually shine the red penlight to look at her). WOW were we excited when we found she's ok, just hovering over/under a clutch of eggs!

She is definitely very protective of them- we barely saw the eggs before she covered over them so we didn't have time to get a great look at how many- maybe a dozen, probably about 8-9mm long? She's now back to "caressing" the eggs.

OK, so... She was at the LFS store for only 3-4 days before we got her, and we have had her for not quite 4 weeks. We know she was collected off the coast of Florida by friends of our LFS owner, and that she was sent to them fairly soon after she was collected.

So forgive us our ignorance, but even after reading a little bit online, we have several questions- how long would she potentially be able to store sperm packets / are these likely fertile??

Do they bother laying un-fertilized eggs?? Is there a way to tell without completely stressing her out?

We know she will probably die pretty soon, but we have no idea as to the time frame... as in a matter of days, weeks, etc?

Will she take a break to snack, or should we let the emerald crab out of jail?

What do we need to do to have the best possible outcome?? When do we transfer into little cups or is that the best thing to do?? We are so not set up for this, but if its at all likely that we might be able to raise even one baby... we're open do doing whatever we need to do.
 
http://www.tonmo.com/forums/showthread.php?t=10133 That is a great thread from a person that also received a fertile Mercatoris. She has raised them and they have laid eggs of their own. She put a great amount of effort into the documentation of raising them. If you don't want to read through the whole thread (I can see why you wouldn't), you can try PMing Dwhatley for help from someone with experience.

It is likely that the eggs are fertile. Female octopuses can store sperm from mating for a long time until they are ready to lay the eggs. They will also lay eggs that are infertile. To tell whether they are fertile or not, you will have to wait for them to develop a little bit. If you can see little octopuses inside, they are fertile. Dwhatley's Merc lived for 12 weeks after laying the eggs. This is the longest documented time for a Mercatoris to live after laying eggs. The mother was spot fed cyclop-eeze and hand fed freshly killed food during senescence. A lot of times the mother will take care of the eggs and do nothing else until she dies. Sometimes she will eat though, like in Trapper's case, though she was difficult to feed.

Anyway hope I helped :).
 
Thanks Echidna09,

It looks like Trapper spent 2 months in captivity before laying eggs so I think we are definitely within the potential time frame for having fertile eggs. Like you said, only time will tell for sure.

I need to do some heavy-duty reading before asking more questions... Thanks again. I'll update as conditions warrant!
Cheers,
Greg
 
Thank you both for your input and for directing our attention to TONMO.... we went ahead and started a journal about Varys brooding her eggs.

We have high hopes that we'll be eventually transitioning into a journal about her babies! We'll be pretty disappointed if it peters out because the eggs were never fertile.
 
WOW.....I know this is the same pic you showed me, but the resolution is so much better online, I hope you guys enjoy your baby octopi, and hopefully the midnight feedings dont get to you ;)
 
Thanks! I just saw what MIGHT be another one of the same species at CCA... if you don't have enough to keep you busy already that is! ;)
 
Fertile!

Tonight we were feeding Varys and she moved enough that we were able to get a good look at her eggs for the first time in quite a while.... on close inspection they're more plump than before and they each have a tiny red-brown embryo!

Update!

We have at least 6 (we think the number is 10) babies that started hatching Friday night (2/22) .... we've posted pics of the little twerps over at TONMO and they're super cute! Doing well, eating cyclopeeze.... and VERY tricky to capture.

Rottbo- we're in Norman Oklahoma, but haven't decided what we're going to do with the babies yet. If we did relocate any to new homes, we'd have to be convinced that they were going to have a good set-up and we're pretty leery about shipping them.

Congrats on the lil ones....I recently lost my Abdopus Aculeatus after she laid an infertile clutch. So you are very lucky indeed.
