aWe found female-mimic males in a freshwater goby, Rhinogobius sp. OR, from Kamo River, Ehime, Japan. Of 171 adult males collected, three had a female appearace. A discriminant analysis showed that they had a spectrum of morphology from a wholly female morph, through a neutral morph, to a somewhat malelike morph. These three males made an extremely higher gametic investment than did the normal males, suggesting that they have the potential for sneaking fertilizations. Among Rhinogobius species, female mimicry might be more common than previously known.
