Intestine worms (nasty pic)

[FinsnFur]

I was cleaning up some picture folders on the PC and came across this one.

I like to cut the stomach open on my bass once in a while to see what they have been eating. I found this inside a nice 18"bass two years ago.

Anyone ever see this before, or know what it is or caused from?

I have seen worms in some of the ocean fish, but they were in the meat and not in the gut. I can't remember the name of the fish I seen them in either. But they look just like the ones in the picture.
