  Three different common species of Rabbitfishes in the Red Sea region were found to be naturally infected by Hexangium sigani Goto and Ozaki, 1929. The encountered parasites were described morphologically and morphometrically by means of light and scanning electron microscopy. Present specimens presented and exhibited a wide range of variability inside the same host and at same locality and accordingly all previous synonyms of Hexangium sigani were presented, shown here and discussed with the previously described forms. These variations included testes position relative to each other and relative to ovary, body spination and uterus extension but these differences were considered to be of minor importance. The SEM disclosed well differentiated three forms of sensory papillae; oral papillae, genital papillae and body papillae which may reflect a variation in the functio.. View More»
