Still life or still lives?

[Kaputnik]

This sort of usage question is interesting to me, possibly less so to others.

Although we all know that the plural of life is lives, it has always seemed intuitively obvious that the plural of "still life" (meaning the kind of painting, and not a person's life which is characterized by stillness) should be "still lifes". I say intuitively, because I've never really worked it out logically. And as I don't move enough in artistic circles for the question to come up very often, I'd never bothered to look it up until now.

So I was interested, when I finally did look it up (well, Google it) just now, to find agreement with my intuition.
