“…Hippolyte inermis Leach, 1815 was intially described as protandric by Reverberi (1950) in a short descriptive paper, a conclusion supported by Zupo (1994) with extensive size -frequency analysis. Zupo et al (2008) observed growth and external sexual morphology in males in the laboratory; in several instances, males lost the male appendices masculinae in a single moult.

The sexual system of two caridean shrimps (Processa riveroi and P. bermudensis) was investigated, stimulated by reports of male to female sex change (protandry) in Processa edulis from European waters. Shrimps used in the study were obtained from monthly samples taken from March 1982 to February 1983 in a Thalassia -Syringodium seagrass meadow in Puerto Rico. Observations on size, sex, and reproductive condition were used to construct monthly size -frequency distributions and sex-ratios by size-class (SC). Males were smaller than reproductive females, but there was extensive overlap in size between males and immature females. A sex-ratio (SR) analysis by SC of the overall year-long population sample showed an equal or female-biased SR in the smallest SC, a male-biased SR in 1-3 intermediate SC, with larger SC dominated by females incubating embryos. Such a population structure might result from slower growth in males than females and higher mortality in larger males. Observations on and allometric analysis of sexual characters failed to identify transitional individuals (sex-changers) intermediate in reproductive morphology between males and females. Thus, a hypothesis of protandry is rejected, and that of gonochory (separate sexes) is accepted in these two Processa species, revealing possible variation in sexual systems among Processa species.

“…Some Cocconeis species have been shown to induce sex reversal in the shrimp Hippolyte inermis , a benthic opportunistic herbivore, but the chemicals that induce sex reversal remain unknown 25 – 27 . Other benthic diatoms produce volatile organic compounds (VOCs) similar to those produced by planktonic diatoms that induce behavioural changes in several species of macrinvertebrates 28 , but studies on the metabolic effects of fast-growing benthic diatoms on benthic invertebrates are still largely lacking 29 – 31 .…”

Diatoms are unicellular algae playing a key role as photosynthetic organisms in the world’s ocean food webs. The chemical ecology of planktonic diatoms is well documented, but few studies have reported on the effects of benthic diatoms on their consumers, also due to difficulties in the collection, quantification and massive culturing of benthic species. Here for the first time we investigate the effects of feeding on two abundantly occurring benthic diatoms, Nanofrustulum shiloi and Cylindrotheca closterium, isolated from the leaves of the seagrass Posidonia oceanica, on the sea urchin Paracentrotus lividus. Adult P. lividus were fed for one month on diets of either one of the two diatoms and on the green alga Ulva rigida, used as a feeding control. By combining morphological, metabolomic and de novo transcriptomic approaches, we demonstrate toxigenic effect on embryos generated by females fed with these benthic diatoms. Furthermore, chemical analysis reveal the presence of polyunsaturated aldehydes only for N. shiloi, and a high production of other oxylipins (cytotoxic compounds on their grazers and on cancer cell lines) for both diatoms, including some additional peaks not correlated to the canonic oxylipins commonly observed in planktonic diatoms. These findings open new perspectives in the study of diatom secondary metabolites influencing their grazers.

“…"Old" and "New" foods were, respectively, administered in each replicate at the rate of 3.5 mg for the first 7 days, gradually increasing up to 8.0 mg as the larvae grew. Exuviae were collected regularly, measured (total length) and examined under a dissecting microscope for signs of sexual maturation (according to Zupo et al 2008).…”

Decapods are important in aquaculture practice and as models for marine biology research, due to peculiar endocrine and physiologic adaptations to various environments. For these reasons, decapods are cultivated. To promote their correct development and sexual maturation, the preparation of balanced diets is crucial. Several diets, both experimental and for aquaculture purposes, have been established, but the set of essential fatty acids is still unknown for most species. Furthermore, fatty acids contained in formulated feeds are differentially sensitive to decay over the storage time. Here we compare growth, maturation and mortality of post-larvae fed on a formulated diet containing Artemia sp., Spirulina sp. and a fatty acid integrator, as administered immediately after its production and after 12 months of storage. The same foods were analysed for their fatty acid contents using gas chromatography. The sets of fatty acids present in differently aged foods corresponded to differences in the growth rates and survival of the model organism Hippolyte inermis cultured in the laboratory. The differences were mainly due to seven fatty acids, whose abundance decreased during the storage, the most important of which were arachidonic and linolenic acid, that are known to be essential for other species of decapods.
