Abstract

In February 2010, a specimen of Urotrygon microphthalmum (total length = 232.4 mm; disc width = 123.1 mm; total weight = 81.97 g) was caught having the external appearance of a male with an abnormality (atrophied left clasper and missing right clasper). Internally, the specimen had only female reproductive organs. The left ovary had yellow follicles (≤ 2.7 mm) and the left uterus had a yellow ovum (5.85 mm). These characteristics indicate that the individual captured was a case of abnormal hermaphroditism, classified as a pseudo-hermaphrodite.
