Abstract
This study reports a comprehensive description of penaeid spermatogenesis (Penaeus monodon) by light and transmission electron microscopy. A conspicuous characteristic of spermatocytogenesis was a ring-like structure with high electron-density adjacent to the nucleus of a primary spermatocyte. During the spermiogenesis from stage I (StI) to stage VI spermatid (StVI), the formation of the acrosome and decondensation of the nucleus were the most notable morphological transformations. StIs were small and compact and they were contained in the syncytia. In the cytoplasm of StII, mitochondrion-like bodies (MLB) participated the extension of perinuclear multi-layered lamellae. The association of MLBs and endoplasmic reticula appeared to contribute to the formation of small cytoplasmic pre-acrosomal vesicles (PV) which coalesced into an acrosomal chamber (AC) at the periphery of StIII. A dense anterior acrosomal body (AB) was formed in the enlarged AC in StIV. The nuclear envelope became disintegrated in StV. At last, an AB-derived spiky acrosome was emerged from AC in StVI. Sperm nuclei became increasingly decondensed during the entire process of spermiogenesis and the nuclear components in the testicular spermatozoa appeared to only contain chains of DNA and nucleosome-contained chromatin.

Abstract
Expression of a sex-specific gene in Macrobrachium rosenbergii (Mr-Mrr), encoding a male reproduction-related (Mrr) protein, has been identified in the spermatic ducts (SDs) and postulated to be involved in sperm maturation processes. M. rosenbergii is the only decapod that the expression and fate of the Mrr protein has been studied. To determine that this protein was conserved in decapods, we firstly used cloning techniques to identify the Mrr gene in two crabs, Portunus pelagicus (Pp-Mrr) and Scylla serrata (Ss-Mrr). We then investigated expression of Pp-Mrr by in situ hybridization, and immunolocalization, as well as phosphorylation and glycosylation modifications, and the fate of the protein in the male reproductive tract. Pp-Mrr was shown to have 632 nucleotides, and a deduced protein of 110 amino acids, with an unmodified molecular weight of 11.79 kDa and a mature protein with molecular weight of 9.16 kDa. In situ hybridization showed that Pp-Mrr is expressed in the epithelium of the proximal, middle, distal SDs, and ejaculatory ducts. In Western blotting, proteins of 10.9 and 17.2 kDa from SDs were all positive using anti-Mrr, antiphosphoserine/threonine, and antiphosphotyrosine. PAS staining showed they were also glycosylated. Immunolocalization studies showed Pp-Mrr in the SD epithelium, lumen, and on the acrosomes of spermatozoa. Immunofluorescence staining indicated the acrosome of spermatozoa contained the Mrr protein, which is phosphorylated with serine/threonine and tyrosine, and also glycosylated. The Mrr is likely to be involved in acrosomal activation during fertilization of eggs.

Abstract
This study describes spermatogenesis in a majid crab (Maja brachydactyla) using electron microscopy and reports the origin of the different organelles present in the spermatozoa. Spermatogenesis in M. brachydactyla follows the general pattern observed in other brachyuran species but with several peculiarities. Annulate lamellae have been reported in brachyuran spermatogenesis during the diplotene stage of first spermatocytes, the early and mid-spermatids. Unlike previous observations, a Golgi complex has been found in mid-spermatids and is involved in the development of the acrosome. The Golgi complex produces two types of vesicles: light vesicles and electron-dense vesicles. The light vesicles merge into the cytoplasm, giving rise to the proacrosomal vesicle. The electron-dense vesicles are implicated in the formation of an electron-dense granule, which later merges with the proacrosomal vesicle. In the late spermatid, the endoplasmic reticulum and the Golgi complex degenerate and form the structures-organelles complex found in the spermatozoa. At the end of spermatogenesis, the materials in the proacrosomal vesicle aggregate in a two-step process, forming the characteristic concentric three-layered structure of the spermatozoon acrosome. The newly formed spermatozoa from testis show the typical brachyuran morphology.

Abstract
This study describes the morphology of the sperm cell of Maja brachydactyla, with emphasis on localizing actin and tubulin. The spermatozoon of M. brachydactyla is similar in appearance and organization to other brachyuran spermatozoa. The spermatozoon is a globular cell composed of a central acrosome, which is surrounded by a thin layer of cytoplasm and a cup-shaped nucleus with four radiating lateral arms. The acrosome is a subspheroidal vesicle composed of three concentric zones surrounded by a capsule. The acrosome is apically covered by an operculum. The perforatorium penetrates the center of the acrosome and has granular material partially composed of actin. The cytoplasm contains one centriole in the subacrosomal region. A cytoplasmic ring encircles the acrosome in the subapical region of the cell and contains the structures-organelles complex (SO-complex), which is composed of a membrane system, mitochondria with few cristae, and microtubules. In the nucleus, slightly condensed chromatin extends along the lateral arms, in which no microtubules have been observed. Chromatin fibers aggregate in certain areas and are often associated with the SO-complex. During the acrosomal reaction, the acrosome could provide support for the penetration of the sperm nucleus, the SO-complex could serve as an anchor point for chromatin, and the lateral arms could play an important role triggering the acrosomal reaction, while slightly decondensed chromatin may be necessary for the deformation of the nucleus.

Abstract
The transforming characteristics of the membrane complex in spermatogenesis of Fenneropenaeus chinensis have been studied by using transmission electron microscopy. Two types of membrane complex have been investigated based on their sources: one originating from nucleus and the other from cytoplasm. The first one, consisted of annular structures, monolayer membrane blebs, and double or multi-lamellar membrane vesicles, emerges in the primary spermatocyte, then diffuses with the nuclear membrane and finally enters the cytoplasm. This type of membrane complex seems to play an important role in the materials transfusion from nucleus to cytoplasm, and it mainly exists inside the primary spermatocyte with some inside the secondary spermatocyte. The latter, originated from cytoplasm, is formed during the anaphase of spermiogenesis. It also exists in mature sperm, locating at both sides of the nucleus under the acrosomal cap. This type of membrane complex mainly comprises rings of convoluted membrane pouches, together with mitochondria, annular lamina bodies, fragments of endoplasmic reticulum, nuclear membrane and some nuclear particles. It releases vesicles and particles into the acrosomal area during the formation of the perforatorium, suggesting a combined function of the endoplasmic reticulum, mitochondria and Golgi's mechanism.

Abstract
The acrosome reaction (AR) was induced in sperm from the brachyuran crustacean Uca tangeri either by mixing male and female gametes in filtered seawater or by treating the spermatozoa with the divalent cation ionophore A23187. This latter method provided a sufficient number of reacted spermatozoa to allow a detailed ultrastructural study of the AR. The process consists of two separate phases: a) initial release of the acrosomal vesicle contents, and b) further elongation of the acrosomal filament, which causes reversal of the rigid capsule limiting the acrosomal vesicle contents. The elongate acrosomal filament consists of an apical perforatorium and a basal columnar structure called here the proximal piece. The former derives from the perforatorium of the uninduced sperm stage with only small ultrastructural changes. The proximal piece forms from myelin-like membrane layers which are initially distributed all around the subacrosomal region and then accumulate in a column at the perforatorial base, thus promoting a sudden forward projection of the perforatorium. The AR in brachyurans is thought to be a passive mechanism that utilizes the negative pressure exerted on the nucleus--caused by emptying of the acrosomal vesicle--for an organized accumulation of membrane-rich material immediately behind the perforatorium, with the final result of the raising of a 3 microns long acrosomal filament.

Abstract
Early events of fertilization were studied in Carcinus maenas by in vitro experiments and ultrastructural analysis; some were found to occur in the lumen of ripe ovaries. The acrosome reaction generally conformed to the usual. Reptantia Decapoda pattern. However, a prominent membrane system continuous with the nuclear envelope and located close to the base of the acrosome tubule characterized the type of spermatozoon observed in Carcinus maenas. Such complex anatomical connections linking the three parts of the reacted spermatozoon (acrosome tubule, membrane system and nucleus envelope) may be significant in relation to the membrane system's contribution to the acrosome reaction. The outer layer of the everted acrosomal vesicle was found to comprise tubular elements ending in bell-shaped corpuscles, deeply interdigitated with the oolemma microvilli during the establishment of the initial contacts between the reacted spermatozoon and the egg plasma membrane. At the site of contact, the oolemma formed in minute fertilization cone, locally depressed by the acrosome tubule. During these early fertilization events, the nucleus, like the other spermatozoon components, was seen to penetrate the egg coatings first, the later to be located near the oolemma.

Abstract
Sperm of the prawn Sicyonia ingentis were studied cytochemically and ultrastructurally. Striking cytological differences were noted between these natantian sperm and previously studied reptantian sperm. In general, the S. ingentis sperm are composed of a spherical main body that is partially encompassed by a morphologically diverse cap region, from which extends a single appendage or spike. The main body houses an uncondensed, Feulgen-positive nuclear region that is partially surrounded by a cytoplasmic band. A single layer of small, 600 A, vesicles lines the periphery of the cytoplasmic band. Large membranous vesicles extend from the inner surface of the cytoplasmic band into the nuclear region. The nucleus is separated from the cap or acrosomal complex by a dense plate and a highly organized crystalline lattice, which is composed of geometric squares that are approximately 350 A in dimension. The cap region also contains convoluted membrane pouches; a central granular core; spherical bodies; an electron-dense, saucer-shaped plate; and a large anterior granule. The convoluted membrane pouches and anterior granule are periodic acid-Schiff (PAS) positive. The anterior granule also demonstrates RNAase-stable red fluorescence with acridine orange staining. A spiralled spike, approximately 6 micron long, extends from the anterior end of the cap. The cap and spike are bound by a double membrane, which results from the fusion of the plasma membrane and the convoluted pouch membrane. The sperm's acrosome is thought to be composed of the two PAS-positive cap components and the spike.
