Apple Snail Embryology

So far our progress in learning the embryology of the apple snail has turned up zip ;( B's snail has laid 3 different egg clusters, but we have not been able to see much under the microscope. At this point we are assume she is either laying unfertilized eggs or we just have no clue what we are doing ;) We'll keep working at it, as it seems the egg supply is endless. Below is a single egg.

Surprisingly, when B tried to remove an egg from the cluster, we found that the cluster was hard. The mositure that was between the eggs when they were laid had hardened into a protective coating. So it is almost like a piece of crystalized honey comb, or something like that, but hard. Which makes getting an intact egg out of the cluster difficult without damage.
As I am typing the above B called out, "Mom come here!" Below is what he found. At the end of the pointer there is a moving "thing". B suspects it is like a worm or bacteria (we need more research). It was great to finally see something. I'm sorry that it is hard to make out what is there. The camera keeps focusing on the moisture and not on the actual this I want to take the photo of. B is still working on the next egg. Maybe there will be more?
The "labratory" where research is taking place. (Yes, that's my downstairs bathroom. Lucky scientist gets to group his specimens in the dining room and use the bathroom for his research.)
