Snail Graveyard

[Beverly]

I still don't know what's killing our snails We made and baited the plastic bottle with PE mysis one night, but got nowhere. That style of trap is so light, it moves around and probably scares off the predator, so I got rid of it I will get two new plastic bottles this morning and cut them into traps and bait them each with all the dead snails we've got in the graveyard. To prevent the trap from moving around, I think we should probably secure it in place by butting rock up against it.

Anyway, on other nights, we have baited a small glass jar covered with plastic wrap leaving a small opening and have seen a huge bristleworm go for the PE mysis. Most mornings with the glass jar trap, the mysis are gone and no snails are dead.

Last night we did not set any traps. THIS morning, my favourite snail was found dead. It was a hitchhiker that was about 4 times the size of any snail I've ever seen and only came out at night This snail came in on the same rock that the snail killer came in on.

And we still hear sharp, but fairly quiet clicking, often after lights out, but for the past few days we hear it during feeding times especially in the morning.

I'm stumped. Could the monster sized bristleworm be killing these snails and the clicking be from a pistol shrimp, or do we indeed have a mantis?

Any and all suggestions, opinions, comments are welcome.
