An intersexual specimen of Pacific Spadenose Shark Scoliodon macrorhynchos was found in the southern Taiwan Strait. It exhibited fully calcified claspers as well as bilateral ovotestes and reproductive tracts of both sexes. Histological analysis of its left ovotestis showed that it contained viable germ cells of both sexes, which allowed potential functionality as either sex physiologically. This specimen represents the first reported case of intersexuality in the genus Scoliodon and is also a rare record of intersexuality in elasmobranchs.
