When predators lurk nearby, male Bahamas mosquitofish (Gambusia hubbsi) change mating strategies, rejecting elaborate courting rituals for more frequent and sometimes forceful encounters with females. But as a recent study shows, mating strategies aren't the only things changing for G. hubbsi when predators abound. The shape and size of the male fish's genitalia are also linked to the presence or absence of predators.
