Yes, that is exactly what I am talking about (your artwork), only there are about 8 of them that wrap around the tissue between the shell and head. They are spaced as if nature wanted them there. If you watch the video and slow it down in spots, you will get a glimpse of all or almost all of them and how they seem in place and spaced. Thingamabobits are close to the inner shell, touching it, but not apart of it. When the snails go into their trapdoors these things are not hanging around. They go into their trap doors when I try to remove it. I think I stated there are 2 baby MS with this, but may have missed that fact. The other MS is not as bad as this one, but it is smaller. I will try to capture more images today. after some zzz
Thanks for interacting with me on this!
