Bluegill Parasite?

[SakranMM]

I took the kids panfishing in Manotick the other day, and I noticed this bluegill swimming around in the shallows with what looked like a weird growth extending from the front of his face...it was white, and looked sort of like an elephant tusk, and was almost equal to the length of the fish's body. I couldn't tell if it had just tried to swallow something too big for his mouth, or if it was some kind of parasitic growth. Anyone ever seen something like that before? It was pretty weird looking.
