In research published in May in the Proceedings of the National Academy of Sciences, biologist Brian Langerhans and colleagues found that large genitals in some fish species (such as the western and Bahamas mosquitofish) represent evolutionary pluses and minuses. Apparently, females prefer well-endowed mating partners, but on the other hand, well-hung males tend to have shorter life spans because, weighted down as they are, they cannot swim away from predators as nimbly as can mosquitofish with smaller endowments.
