Sexual selection is a tough gambit. The famous example of walking the line between females and food is the Peacock. The male's tail is a Peahen magnet, with a large, full tail advertising good genes. It is also a target and a hindrance. A tiger looking for a meal could easily spot a peacock's tail, and it's unlikely that a big bunch of tailfeathers would make it possible to escape. The selection for tailfeathers goes between two variables: big enough to attract females, light enough to escape predation.
