Description
Fig. 1. Serrasalmus maculatus spermiogenesis. A to C - Longitudinal sections of early spermatids during the nuclear rotation process. D and E - Longitudinal sections of early spermatids during the chromatin condensation process. F, G and J - Midpiece cross sections. H and I - Flagella in cross sections. Scale bars: A to C = 1 µm; D = 0.85 µm; E = 0.9 µm; F = 0.9 µm; G = 0.75 µm; H = 0.04 µm; I = 0.75 µm; J = 0.6 µm. A: axoneme; C: centriole complex; D: distal centriole; F: flagellum; M: mitochondria; N: nucleus; P: proximal centriole; V: vesicle; Asterisk: fins; Arrow: electron dense material; Arrowhead: cytoplasmic canal; Double arrow: nuclear fossa.
