Need some help please

Anybody know what these are? I bought the wall hammer coral yesterday but i also found this weird coral that's attached to the wall of the hammer coral.

second picture: I found this scar / scab on the body of my nassarius snail. I thought it was a flake or something so I tried to remove it but I found out it's stuck on the actual snail and cannot be remove unless I forcefully rip it off the body. Anybody know what that is?

Thank you.

Nothing to worry about, thats its "door"

oh thank you for that clarification. Why is mine so dark though compared to the picture you have.

That, I can't explain maybe an expert might chime in on that, Im not very familiar on nassarius species, so could be a different species, also could be contributed to environmental factors, collection area, diet etc etc.

Just know that it is its "door" and not a parasite like some flatworms that feed on gastropods.

Hope this helps!
