wierd thing on snail and another weird thing

I have 2 items i need help finding out what they are. One is an orange thing that is on the back of one of my snails.

The next is a weird green spiral thing I found in my sand.

Thanks for all the help!

 

Image 1 looks like it could be a Vermetid Snail.

Have no idea on the last two images.

 

I don't know on any of them but the green spiral thing is cool

 

+1 on that.. Definitely looks like a vermetid snail - not harmful at all.

not sure about the green spiral either.. is it hard/soft?

 

+1 to the snail, i would get rid of it cuz they spread and can become a nuisance to corals. As for the spiral thing, i had one like it in my sand bed at one point, but it was orange, it was just a shell in my case.

 

I have not idea if it was soft or hard. It was their for a couple hours then it disappeared. As for the snail, where do they come from? It stays on the back of the other snail all the time. Is that normal? It does look like a snail if you look close I have just never seen one like that before.

Thanks for all the help!

 

The Vermetid is probably fine. No they do not look like snails at all and some think they are more like a worm. They can bother corals but since yours is on the move I do not see an issue. They become an issue when they are located next to corals with continuous exposure. If it becomes an issue simply use some super glue gel on the opening, just a tiny amount.

 

What a horrible way to go! could you imagine.. not being able to open your only door to the outside some day.....

(not being too serious here...)
