2. No pic, but from looking at the HH thread could be a sundial, BUT it travels with the shell upright. It is hard to tell the details as it the size a pin head. I could not get a pic that showed more than a white dot...but to the eye there is a sort of checkered pattern of white and tan/brown.
3. On the glass are even smaller snails(?), are these perhaps babies of some type of snail I have including (turbo, astria, or nassirus)?
1 - Horse Conch. This animal is a predator. It will eat anything it can catch. Snails, Clams, etc.
2 - The distinction between Collonista & Sundial is a pyramid shaped covering over the shell opening that the Sundial has.
3 - Could be anything. My guess would be Ilyanassa obsoleta (not really Nassarius sp.).
