Is this common in stingray litters?

[davenmandy]

Had a litter of 7 pups today, but I also found 3 underdeveloped embryo's. Is this common in stingray litters? The litter wasn't as fat this time around. This is also mama's third litter in a row, 3 litters in a bit over a year when you consider gestation. I am giving her a bit of a break this time. I am specifically wondering how it is possible that she delivered 7 healthy pups with these dead embryo's when a few threads down keepinfish lost a P14 because the baby died and decomposed inside of her, poisoning her. These guys are extremely underdeveloped so must have been like this for a while. Should I be concerned about the way mama delivered these? Did something go wrong or does this fall in the category of "these things happen sometimes"? Also, anyone have an educated guess as to how old these guys were when they "died? Maybe I didn't feed mama enough

very good point.... how would having three dead pumps in with a healthy litter not cause a problem with the other pups or the mother...

glad you had some healthy ones. if mom is eating well i think your going to be fine!

where is the pictures of the other pups?

My last litter was somewhat like this, mom wasnt ever fat and I never even realized she was pregnant until I seen her give birth to one live pup and one underdeveloped which looked exactly like what you have pictured above. She then held on to two more pups for over two weeks before dropping those live although incredibly small (one never ate anything and died within a week and one barely ate but died after about 3.5 weeks)

Only thing I can think of keepinfish is because they were so underdeveloped they didn't necessarily "rot" like yours did, they just kind of stayed jelly or whatever so it may not have complicated much. I am more concerned about mscamp02 post though because it seems indicative of a bad pregnancy. I have to give mama a break now, wonder how long I should let her rest for.

i was seeing movement on mine until the last week sometime. so your probably right.

I think this is spot on.

This would be similar to a miss carriage IMO. I think Just mother nature taking its course. I guess there is no way in knowing how often it happens in the wild. Probably not as often. This also happens in cats and dogs. As for female dying with rotted ray, pregnant women have miss carriages at different time stages. Some very early and some later into the pregnancy. Women that have late miss carriage must have a minor surgery to remove dead fetus or it could be fatal for the women, as in keepeinfish case

I've had it several times. Healthy litter with a few underdeveloped dead ones.

No idea why? Any more details to share, like we're they big litters? Tough pregnancy? Subsequent pregnancies without rest? What were your thoughts on why when you found em?

I really don't think it's anything other than nature. I haven't had a ton of them, but enough to say it's not a rarity. As with any pregnancies there are no guarantees. It's just a numbers game, so many will be aborted, so many will be albino, so many be undeveloped.l, etc. I'm always moving rays from tank to tank and changing water and food, but I don't think that's it. Just nature. My opinion of course.
