Ultrastructure of spermatozoa from three genera of crayfish Orconectes, Procambarus and Astacus (Decapoda: Astacoidea): New findings and comparisons

Original language description

Ultrastructure of spermatozoa of three crayfish genera including Orconectes limosus (Rafinesque, 1817), Procambarus clarkii (Girard, 1852), and Astacus leptodactylus (Eschscholtz, 1823) was studied using transmission electron microscopy. The length of the acrosome was significantly greater in A. leptodactylus (4.5 +/- 0.65 mu m) than O. limosus (1.7 +/- 0.2 mu m) and in O. limosus compared to P. clarkii (1.46 +/- 0.16 mu m). The width of the acrosome was significantly narrower in P. clarkii (2.45 +/- 0.2 mu m) than O. limosus (4.77 +/- 0.51 mu m) and in O. limosus compared to A. leptodactylus (8.23 +/- 0.9 mu m). Also, the length:width ratio was significantly greater in P. clarkii (0.6 +/- 0.07) than A. leptodactylus (0.55 +/- 0.08) and in A. leptodactylus compared to O. limosus (0.36 +/- 0.05). The acrosome complex and nucleus are located at the anterior and posterior of the spermatozoon, respectively. The acrosome complex organelle is divided into two main parts: the main body of the
