Abstract
  • Scanning and transmission electron microscopy were used to investigate the fine structure of the sperm of the sparid fish Pagellus bogaraveo. The spermatozoon of P. bogaraveo belongs, like that of the other sparid fish, to the teleostean \" type I\" spermatozoon with the flagellar axis insert perpendicular to the nuclear fossa. It has an ovoidal head, a short, cylindrically shaped midpiece and a long tail region. The nucleus reveals a deep invagination (nuclear fossa), in which the centriolar complex is located, and a satellite nuclear notch shaped like a golf club. The two centrioles are perpendicular to each other and show a conventional \" 9+0\" pattern. The distal centriole is attached to the nuclear envelope by means of basal feet and radial fibers made of electron-dense material. Below the basal plate, plasma membrane pinches in, and the necklace, a specialized connection joining axonemal doublets to the plasma membrane, is visible. The short midpiece houses one mitochondrion. The flagellum is perpendicularly and eccentrically with respect to the nucleus and contains the conventional \" 9+2\" axoneme. © 2009 Elsevier Ltd.
