“…Molecular analysis of VIHs isolated from females of a few crustacean species shows that they consist of signal peptides (20-31 amino acid residues) and mature peptides (77-83 amino acid residues; Fig.3). They also show a considerable degree of sequence similarity with MIH, including the preservation of six cysteine residues at the same relative locations (Demeusy, 1953;Leung-Trujillo and Lawrence, 2009;Nagaraju and Borst, 2008;Rotllant et al, 1993;Wongsawang et al, 2005;Yano et al, 1988) forming three intramolecular disulfide bonds (1-5; 2-4; 3-6 fashion); these are major chemical forces, which help to maintain the VIH tertiary structure (Fig.3) (Soyez, 2005;Udomkit, 2000;Nagaraju et al, 2009). Reverse phase high performance liquid chromatography (RP-HPLC) analysis revealed that the neuropeptide in H. americanus has two enantiomeric isoforms with the fourth residue being either ltryptophan or d-tryptophan.…”

SummaryControl of reproductive development in crustaceans requires neuropeptides, ecdysone and methyl farnesoate (MF). A major source of neuropeptides is the X-organ-sinus gland (XO-SG) complex located in the eyestalk ganglia of crustaceans. The other regulatory factors (either peptides or neuromodulators) are produced in the brain and thoracic ganglia (TG). Two other regulatory non-peptide compounds, the steroid ecdysone and the sesquiterpene MF, are produced by the Y-organs and the mandibular organs, respectively. In the current review, I have tried to recapitulate recent studies on the role of gonadal regulatory factors in regulating crustacean reproduction.Key words: crustaceans, reproduction, gonads, X-organ-sinus gland, peptides. THE JOURNAL OF EXPERIMENTAL BIOLOGY4 crustaceans, the testis contains 10-15 lobes each composed of many seminiferous tubules, whose shape changes according to the stage of spermatogenesis. Spermatogenesis starts in the undifferentiated seminiferous tubules (proacini) at the top of each lobe. Meiotic activity occurs in the acini that develop proacini somewhat proximally from the top of each lobe. In this stage, the lobules contain mostly primary spermatocytes. Differentiation of secondary spermatocytes and spermatids takes place in the seminiferous tubules, which lie in the center of each lobe. All these seminiferous tubules are filled with spermatocytes and spermatids surrounded by a layer of otheocytes of mesodermal origin. The hormonal control of spermatogenesis is not completely understood in crustaceans. There is information on MF as a reproductive hormone in males. The female reproductive systemThe reproductive system of female crustaceans consists of the paired ovaries, oviducts, gonophores and an external sperm reception area. The ovarian lobes are connected by a central bridge of ovarian tissue (Fig.1D). The ovarian lobes are symmetrically arranged and lie in the cephalothorax on the top of the stomach and hepatopancreas (HP). An oviduct arises laterally from each ovary at a point just beside the position of the heart. It extends ventrally and opens through a gonophore in the abdomen. In sexually receptive females, each pore is equipped with a large tuft of long setae, which apparently serve as a tube for the passage of ova. In the fully mature state, the shapes of ovarian limbs can be distinguished only with difficulty as the ovary fills the thoracic region of the body cavity completely.In the majority of female Malacostraca, oogonial proliferation and ovarian differentiation take place when the ovary is translucent to opaque white (previtellogenic ovary). During vitellogenesis the color of the ovary changes from pale yellow (vitellogenic stage I) to orange (vitellogenic stage II) and it then becomes brown (vitellogenic stage III) to dark brown prior to spawning. Maturation of the ovary also includes an increase in the size of the ovary as the oocytes proliferate and increase in diameter, due to yolk deposition.

“…b In contrast, the barnacle Pollicipes elegans shows biased paternity in favor of genetically similar males (genetic similarity index after Li et al 1993;Plough et al 2014) events such as oviposition, copulation, or receptivity, which may increase encounter probability with favored males. Intensified male-male competition can be provoked through female chemical signaling mediated by sex pheromones (Berry and Breithaupt 2010;Okamura and Goshima 2010), which may also elicit male search and guarding behavior (Yano et al 1988;Bouchard et al 1996;Sneddon et al 2003). The use of sex pheromones for social communication is common and well documented in crustaceans (e.g., Ryan 1966; Atema and Engstrom 1971;Dunham 1978;Gleeson 1980;Imafuku 1986;Díaz and Thiel 2004;Breithaupt and Thiel 2011), and female pheromone signaling to manipulate competitive male behavior could be widespread.…”

Cryptic Female Choice in Arthropods

Cryptic female choice may be common among crustaceans , but few studies have thoroughly examined it in this diverse taxonomic group. Herein, we summarize current genetic evidence for multiple paternity and skewed offspring ratios in crustaceans, and document observations that could suggest cryptic female choice. Behaviors indicative of cryptic female choice have been reported from numerous crustacean taxa (e.g., crayfish , hermit crabs , isopods ), showcasing a diverse array of behavioral mechanisms such as failed copulations, spermatophore removal , selective sperm passage, chemical signaling , adjusting duration of receptivity, delayed copulation , or discriminative reproductive investment in favor of preferred males. We highlight a few case studies, in which a suite of different cryptic behaviors permits females to maintain control over fertilizations. The possibility of selective sperm–egg interactions is briefly discussed, and parallels to other aquatic invertebrates are drawn revealing similar cryptic choice mechanisms. The disparity of body forms and reproductive strategies found in crustaceans and the fact that they inhabit many different habitats with variable selective environments makes them an ideal model taxon for future studies on cryptic female choice

The morphology of the reproductive system of a stenopodidean decapod is described here for the first time, with an interpretation of the sperm transfer process. Pairs of adults of Stenopus hispidus were maintained under laboratory conditions to observe reproductive cycles. Mating behavior and sperm transfer were video-recorded for analysis. After copulation, the shrimps were anesthetized and dissected to record the shape and location of the gonads, and pleopod morphology was described and illustrated. The reproductive systems (RS), thoracic sterna, and male and female genitalia were observed by scanning electron microscopy. The male reproductive system was restricted to the cephalothorax and was highly reduced compared with that of other decapods. Only the first pair of pleopods may be involved in the sperm transfer process; there was no appendix masculina on the second pair of pleopods as in many other decapods. The ovaries of prespawning females occupied much of the cephalothorax and reached to the 3 rd abdominal segment. The oviducts were short and simple, without structures for sperm storage. We conclude that the male deposits a simple spermatophoric mass onto the posteroventral surface of the female and fertilization occurs externally as mature oocytes are subsequently spawned. This mode of sperm transfer and egg fertilization is ancestral within the decapod suborder Pleocyemata. As in some other animals, the relatively small size of the testes in S. hispidus may be related to the monogamous mating system, which may minimize selection for a large volume of sperm production.
