“…Finally, these results (based on 176 males studied without any signs of sex reversal), altogether with our previous studies (Cobos et al 2005;Manjón-Cabeza et al 2009), support the existence of a gonochoric structure of the studied population of H. inermis (from Zostera beds) like has been described recently in other species of the same genus such as H. williamsi Schmitt 1924 H. obliquimanus Dana 1852 (Espinoza-Fuenzalida et al 2008;Terossi et al 2008).…”

“…However, two different studies from our laboratory have found no evidence for hermaphroditic sexuality in adult specimens of this species after a careful examination of the morphology of the reproductive structures (Cobos et al 2005) and an exhaustive study of its population structure and absolute growth (Manjón-Cabeza et al 2009). Recent studies regarding the reproductive system in other species of Hippolyte have not found either any cases of sex reversal (Espinoza-Fuenzalida et al 2008;Terossi et al 2008), and consequently they were described as gonochoristic species.…”

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 location of gonopores on the third pair of pereiopods in females and on the fifth pair of pereiopods in males is in line with the previous literature on caridean shrimps (Mascetti et al 1997; Espinoza-Fuenzalida et al 2008; Terossi et al 2008; Tóth and Bauer 2007, 2008; Manjon-Cabeza et al 2011). The shape and structure of male gonopores in our study are similar to those observed by Espinoza-Fuenzalida et al (2008) in Hippolyte williamsi . Female gonopores in H. inermis are characterised by the presence of a flap, just distal to the gonopore opening, at the proximal end of the third pair of pereiopod coxae.…”

“…A gonochoristic sexual system has been demonstrated in congeneric species viz. H. williamsi (Espinoza-Fuenzalida et al 2008), H. obliquimanus (Terossi et al 2008), and H. niezabitowskii (Manjon-Cabeza et al 2011). As expected, the number of females in the treatment CTRL+ was higher than in the CTRL−, indicative of the process of sex reversal triggered by the apoptogenic compounds present in the CTRL+ food (Zupo and Messina 2007).…”

The sex change of the caridean shrimp Hippolyte inermis Leach: temporal development of the gonopore morphology

2018

Sex reversal is a process observed in several marine organisms, including some lineages of caridean shrimps. We investigated the gonopore shape and size, to study the sex reversal using Hippolyte inermis as a model. A method was developed which can be applied to identify the sex in juveniles of H. inermis, especially, useful when the standard method of sex assessment is not applicable. The position and the shape of gonopores was recorded under a light macroscope. The sex of mature individuals was then determined by observing the presence/absence of the appendix masculina. In addition, analysis of ontogenetic changes of gonopores were performed to compare their morphology with other species of shrimps whose gonopore morphology was previously known. Female gonopores are located at the far proximo-medial end of the third pair of pereiopod coxae and distally they bear cup-shaped structures, whilst male gonopores are located at the far proximo-medial end of the fifth pair of pereiopod coxae and they have a simpler structure. The shape and structure of gonopores in H. inermis resembled that of other caridean decapods. Intersex individuals were never observed, although this species was demonstrated to be protandric. This observation confirmed previous assumptions indicating that the process of sex reversal is very fast in H. inermis and that it takes place within a single moult. The identification of sex based on the position and shape of gonopores is feasible in this species, and it provides helpful insights for studying sex reversal in small decapods.

“…Most caridean shrimps are gonochoric, with individuals in a population producing only male or female gametes during their entire life. Well-studied examples include Rhynchocinetes typus (Correa et al, 2000), Hippolyte obliquimanus (Terossi et al, 2008), Pontonia margarita (Baeza, 2008a), and Hippolyte williamsi (Espinoza-Fuenzalida et al, 2008). The second most common sexual system is protandry.…”

In his formal plan for the Institution, Joseph Henry outlined a program that included the following statement: "It is proposed to publish a series of reports, giving an account of the new discoveries in science, and of the changes made from year to year in all branches of knowledge." This theme of basic research has been adhered to through the years by thousands of titles issued in series publications under the Smithsonian imprint, commencing with Smithsonian Contributions to Knowledge in 1848 and continuing with the following active series: Smithsonian Contributions to Anthropology Smithsonian Contributions to Botany Smithsonian Contributions in History and Technology Smithsonian Contributions to the Marine Sciences Smithsonian Contributions to Museum Conservation Smithsonian Contributions to Paleobiology Smithsonian Contributions to ZoologyIn these series, the Institution publishes small papers and full-scale monographs that report on the research and collections of its various museums and bureaus. The Smithsonian Contributions Series are distributed via mailing lists to libraries, universities, and similar institutions throughout the world.Manuscripts submitted for series publication are received by the Smithsonian Institution Scholarly Press from authors with direct affi liation with the various Smithsonian museums or bureaus and are subject to peer review and review for compliance with manuscript preparation guidelines. General requirements for manuscript preparation are on the inside back cover of printed volumes. For detailed submissions requirements and to review the "Manuscript Preparation and Style Guide for Authors," visit the Submissions page at www.scholarlypress.si.edu.

Foreword N early two-thirds of Earth's surface is covered by the ocean, a global system essential to all life. Impacts on one part of the ocean can have worldwide effects. The ocean moderates our climate, provides valuable resources, and produces at least half the oxygen we breathe: it makes our planet livable. We know little, however, about the physical, chemical, geological, and biological aspects of this crucial life support system. s m i t h s o n i a n c o n t r i b u t i o n s t o t h e m a r i n S M I T H S O N I A N C O N T R I B U T I O N S T O T H E M A R I N E S C I E N C E S MARINE BIODIVERSITY, EVOLUTION, AND SPECIATION S M I T H S O N I A N C O N T R I B U T I O N S T O T H E M A R I N E S C I E N C E S i i i • S M I T H S O N I A N C O N T R I B U T I O N S T O T H E M A R I N E S C I E N C E SThe Smithsonian Institution, in efforts to increase knowledge about the ocean, has established a ...
