Confusion

So what is the difference between life insurance and Funeral Insurance? I really have no idea. I read something that mentioned it and I realized that I have no idea what the difference is. If you have life insurance do you also need funeral insurance? I always thought that life insurance covered all that stuff too. Maybe it's just if your life insurance is bad, but I would think that if you couldn't qualify for good life insurance then how would you get good funeral insurance? Clearly I have no idea about this stuff. I suppose it doesn't really matter, I don't need to understand everything.
