“…Spermatozoa of natant decapods have been profusely studied in many species (Spitschakoff 1909;PochonMasson 1965PochonMasson , 1968PochonMasson , 1969Lu 1976;Koehler 1979;Kleve et al 1980;Lyn and Clark 1983;Papathanassiou and King 1984b;Shigekawa and Clark 1986;Griffin et al 1988;Bauer 2000). The results of the studies of the caridean spermatozoa have shown a great variability in shape, but their pattern is generally similar to that of H. inermis.…”

The present work completes a series of studies on the biology of the shrimp Hippolyte inermis Leach 1815, where we suggested the species to be gonochoristic. The morphology of the male reproductive system (testes, vasa deferentia, gonopores) and the different stages of male germ cell development are described for the first time in the genus Hippolyte, using TEM, SEM, and histological methods. All males from 1.70 to 3.42 mm in carapace length had active testes and well-developed vasa deferentia. No case of sex reversal could be found.

“…The vesicles are thought to derive from endoplasmic reticulum cisternae; some could coalesce with the large proacrosomal vesicle, contributing flocculent material to its contents. Membrane complexes located close to both the nucleus and the developing acrosomal structure are universally present in spermatids of decapod crustaceans (Moses 1960(Moses , 1961Yasuzumi 1960;Kaye et al 1961;Anderson and Ellis 1967;Pochon-Masson 1968a;Langreth 1969;Reger 1970;Pearson and Walker 1975;Arsenault et al 1979;Koehler 1979;Arsenault 1984;Papathanassiou and King 1984;Haley 1986;McKnight and Hinsch 1986;Shigekawa and Clark 1986;Medina and Rodrfguez 1992 a).

“…Conversely, the multistellate sperm of the non-caridean Pleocyemata (comprising the assemblage of the older Reptantia) show several appendages or arms of nuclear or cytoplasmic origin, the acrosome lacking any outstanding prolongation. Abundant references to the sperm ultrastructure in "natantians" are available (see reviews by Jamieson 1987, and Felgenhauer and Abele 1991, including the Dendrobranchiata (Clark et al 1973(Clark et al , 1981(Clark et al , 1984Yudin et al 1979;Kleve et al 1980;Shigekawa and Clark 1986;Ogawa and Kakuda 1987;Clark and Griffin 1988;Griffin et al 1988;Dougherty and Dougherty 1989;Demestre and Fortufio 1992) and the Caridea (Pochon-Masson 1968bArsenault et al 1979Arsenault et al , 1980Koehler 1979;Dupr6 and Barros 1983;Lynn and Clark 1983 a, b;Arsenault 1984;Felgenhauer et al 1988;P6rez et al 1991). Whereas caridean spermiogenesis has been reported for PaIaemonetes paIudosus (Koehler 1979), Crangon septemspinosa (Arsenault et al 1979(Arsenault et al , 1980Arsenault 1984) and Palaemon serratus (Papathanassiou and King 1984), the only previous ultrastructural account of dendrobranchiate spermiogenesis concerns the sicyoniid Sicyonia ingentis (Shigekawa and Clark 1986), the sperm of which clearly differs from those of the Penaeidea (Clark et al 1973;Felgenhauer et al 1988; Dougherty and Dougherty 1989; Abele 1991) in possessing a more complex acrosomal structure.…”

Spermiogenesis and sperm structure in the shrimp Parapenaeus longirostris (Crustacea: Dendrobranchiata): comparative aspects among decapods

Early spermatids of the dendrobranchiate shrimp Parapenaeus longirostris (Lucas, 1846) have a spherical nucleus with large patches of heterochromatin, surrounded by a cytoplasmic mass that contains the conspicuous proacrosomal vesicle. The highly polarized mid spermatid mainly consists of the nuclear region, displaying a discontinuous nuclear envelope, and a large proacrosomal vesicle located at the opposite side of the cell. The most recent spermiogenic transformations primarily concern elongation of the proacrosomal vesicle to form a tapering spike. This results in the typically tack-shaped sperm of natantian decapods. The initial steps of spermiogenesis in the two studied dendrobranchiates prove to be parallel to reptant spermiogenesis in some respects, namely rupture of the nuclear envelope, chromatin decondensation and differentiation of electron-dense regions within the proacrosomal vesicle content. Specifically, whereas the anteriormost condensation gives rise to the operculum in brachyurans, in dendrobranchiates it becomes the apical portion of the spike. Despite an unquestionable morphological similarity between the sperm of carideans and dendrobranchiates, spermiogenesis in both groups displays meaningful differences. Spermatids of caridean shrimps lack a distinct proacrosomal vesicle. In the course of spermiogenesis, the spike arises from aggregated cytosolic materials; hence it is not membrane-bound. Unlike in other decapods, caridean sperm do not undergo a conventional acrosome reaction, since exocytotic events are not involved in this process. The above arguments suggest that, in the Decapoda, separation into three sperm classes is more suitable than the two traditionally accepted classes. The dendrobranchiate and reptant sperm types share a humCommunicated by S. M. P6r6s, Marseille A. Medina

“…This type of sperm has different shapes in different groups of shrimps. The Penaeidea sperm is tack-shaped, as are those of Penaeus setiferous, Penaeus aztecus, (Clark et al, 1973;Brown et al, 1976) and Sicyonia ingentis (Clark et al, 1981a(Clark et al, , 1981bYudin et al, 1979Yudin et al, , 1980Kleve et al, 1980), while the Caridea group has sperm with a main bell-shaped body containing the chromatin and a spike in the vortex of the body, as does the sperm of Paleomon elegans (Pochon-Masson, 1969); Paleomonetes paludosus (Koheler, 1979) and Macrobrachium rosembergii (Sandifer and Lynn, 1981;Lynn and Clark, 1980, 1983a, 1983b, or an inverted umbrella shape, as in the sperm of Rhynchocinetes typus (Dupré and Barros, 1983). It has been reported that R. typus constitutes a third type of spermatozoon, an exception to the dendr obranchiata pattern , since this sperm presents a single spike like all the groups, but with 9-13 radial arms (Dupré and Barros, 1983) with actin fi laments and tubuline-like proteins (Perez et al, 1990), which is a characteristic of the pleocyemata group.…”

The destination of sperm components after penetration into the oocyte and male pronuclear organization have not been established either.…”

This review compiles all the research done on gametes and fertilization in the rock shrimp, R. typus, and describes the sequence of events from the fi rst gamete interaction to zygote formation and the fi rst cleavage of the embryo, with light, fl uorescence confocal and electron microscopes. Early studies showed that sperm from the vas deferens have a tack-shape with a "needle-like process" or rigid spike (RS) that extends from a semi-spherical body that contains the arms with chromatin and spines. Upon contact with seawater and by action of Na +, the arms and spines extend, producing an inverted umbrella form of the spermatozoa. The fi rst sperm-oocyte interaction occurs between protein receptors type lectins of the sperm RS and oocyte chorion sperm ligands. These ligands contain residues of α-Glu, Man (α 1-3) Man, α and β-GlcNAc and α-GalNA terminal residues. It was found that α-Man and GlcNAc residues are the ligands that are directly related to the adhesion process and further penetration of sperm. After this fi rst interaction, the RS enters the oocyte envelope by the action of a trypsin-like enzyme, rhynchocinecine, present in the acicular process. Later, arms and spines penetrate the oocyte cytoplasm, where the chromatin of the arms begin to migrate to the central area of the sperm, condensing in a cup-shaped structure near the connecting piece, which forms the male pronucleus.
