LOL.....I got as many as I could off the site. I'll have to search some backup disks to see if I have more. I added the pics and video in the Additional details portion.

I guess if you want to see 60DPS photos, I can ask Joe to take pictures of his. He got his starter snails from me.

yup yup!! This is a nice journal for me to see as well!! Especially with the egg casing and count details as it correlates with the data I've been collecting over the past few months. Gale, have you watched the egg development enough to notice whether or not the third egg is typically a nursery egg most of the time or whether it develops?

Joe, I think in that youtube video above, http://www.youtube.com/watch?v=RgOuvHfIHdE , it shows three fully developed nassarius in the egg case and they are starting to break out. Most eggs that I've noticed have had either two or one snail that developed.

ah, that correlates to what I'm seeing, typically development of all three eggs doesnt happen. While nursery eggs is common appearance I cant help but wonder that with different (read, better) nutritional profiles the adults may be able to create fully viable capsules.

That could be true Joe, but I would assume that your snails get a very good nutritional program because of all the food you raise and give to them hehe.

Just a followup, was looking at the hatch report and the dates aren't making sense. Maybe it's just because I haven't watched my own yet to document. Is it really a 6 week incubation period between spawn and hatch?

No.....you're right... I believe the incubation period is about 2 weeks.... 3/7/08 was spawn 3/22/08 was hatch oops....should have followed my thread on projectDIBS LOL

Collumbellids are about four weeks. It's possible.

3/7 and 3/22 is close, I'm recording incubation periods ranging from 14 to 28 days dependant on temp and salinity this would put you at approximately 15 days with times not perfectly recorded, in line with my findings thus far!!

It's really tough to keep track of number of days and times especially with these guya and columbellids because they lay so many eggs that I lose track of which one I'm tracking LOL. If you notice in the video, there is a red circle around the egg capsule just so I could remember which capsule I was tracking hehe.

yep noticed that Sadly at this point I've got these guys in two's separated sitting in mason jars in water baths.... Trying to figure out how to sex them, the timings, the food requirements, temp and salinity effects.... so this is marine biology... how utterly.... tedious

Where can I find more info on that "egg casing" I would assume that is man made because my snails lay eggs all the time, but it is just a string of eggs, with no protection. Thanks, Adam

If you watch the video in this thread, you'll see a clear egg casing with three snails trying to get out of it. I don't know what normal Nassarius eggs look like. I know Cerith snails lay strings of eggs but don't know about different Nassarius such as Nassarius vibex.

Yeah I saw it... I thought you put it there to protect them, but I guess not. I would like to breed some snails as they all already lay eggs in my DT weekly. I just need to do some more reading on this topic. Thx
