Veteran nassarius snail

[haleyf1024]

So, when first setting up my CUC I got nass snails, later found out some were tongan. This guy is the veteran of the tank, as he has obviously been through some stuff by the looks of his snout. Its longer than the other's and zig zags and looks like it tried to branch off in a few spots. My guess is that he got in a fight with my emerald crab or a hermit. Anyone else ever seen a nass snail like this? He acts fine and it doesn't seem to bother him.
