I believe it is called a ratfish because of the shape of the head and the long, skinny tail. Not because of teeth, if it has any. In any case, I have to admit I've never seen a rusty or gummed up ratfish.
FWIW, I Googled "ratfish oil". Came up with lots of uses but no mention of using it as a lubricant.
