Intraovarian oocytes were up to 115 µm in diameter, with germinal vesicle about 50 µm and single nucleolus 20 µm in diameter. Oocyte envelope is 2–3 µm thick. Spermatogonia proliferate in testes; spermatogenesis occurs in the coelomic cavity. Spermatids are joined in tetrads. Spermatozoa are ect-aquasperm with small acrosome, spherical nucleus 2–3 µm in diameter, spherical mitochondria probably four in number, and a long flagellum.
