Help Seahorse skin?

I just got a trio of seahorses from my LFS. However, one female, has some black thing hanging from her side of her face more like towards the neck if that makes sense. It doesn't seem to bother her, she keeps eating and running around the tank with the other seahorses. It sort of looks like skin or maybe even poop? Under the black thing that is hanging is her normal skin. Does anyone have any ideas what this may be?
