Many animals choose mates that look or act like themselves. Using empirical and modeling approaches, we explore patterns of pairing based on body size in two species of pipefishes. Despite laboratory experiments that show males and females have preferences for larger body size, we find no evidence of size-assortative mating, demonstrating a disconnect between preferences and real patterns of mating in nature.
