Morphology and ultrastructure of beluga (Huso huso) spermatozoa and a comparison with related sturgeons
The ultrastructure and morphology of beluga spermatozoa (Huso huso) (Acipenseridae, Chondrostei) were studied by scanning and transmission electron microscopy. Spermatozoa of 51.27 ± 4.71 μm total length (mean ± SD) were typical of sturgeon and paddlefish spermatozoa. Each consisted of an elongated...
