Silver Redhorse (Moxostoma anisurum)

Much like other redhorses and their sucker kin, the silver redhorse is a bottom-feeder, vacuuming up mollusks and insects as it pleases. But all that food stuff is boring compared to its means of reproduction, which could be considered quite risqué. What brings true attention to this fish is this: during late spring in tributaries of Lake Superior, two males join a resting female and fertilize on either side of the female as eggs are laid. This practice is enacted because males, called "v-males," outnumber the females. So what do you think? Ménage à trois, ou pas?
