“…In this study in agreement with that reported by Faimali et al (2014), one acute and one sub-lethal endpoint were evaluated, in order to verify the neurotoxicity of ES and CPF on A. aurita ephyrae.…”

“…For each concentration, three multi-well replicate plates were prepared, each containing eight ephyrae individually placed in each well to avoid interactions among organisms (Faimali et al, 2014). Plates were then sealed and kept in the thermostatic room at 20°C in dark conditions.…”

“…In fact, it has been recently reported that jellyfish are sensitive model organisms to polycyclic aromatic hydrocarbons (PAHs), heavy metals, organic chemicals, and toxic compounds, (Almeda et al, 2013;Huang et al, 2013;Faimali et al, 2014). Most of these studies focus on ephyrae, the planktonic young jellyfish stage that is produced by benthic polyps during an asexual reproduction process called strobilation, a special type of transverse division (Holst, 2012).…”

“…The use of ephyra stage of the common moon jellyfish Scyphozoan Aurelia aurita (Linnaeus, 1758) has been recently proposed in ecotoxicological bioassays, and the methodological protocol using Cadmium nitrate and sodium dodecyl sulfate as toxic reference compounds (Faimali et al, 2014) has been standardized; the results of Faimali et al 2014 indicated that A. aurita ephyrae represent a suitable model organism for ecotoxicological bioassay both in term of ecological relevance and sent. For this reason, it results challenging to extend the investigation on the effects of contaminants on jellyfishes to a widen class of pollutants.…”

The aim of this study was to analyze the toxicity of two neurotoxic compounds on the ephyra stage of the Scyphozoan jellyfish Aurelia aurita, an innovative and sensitive model organism recently proposed in ecotoxicological bioassays. Indeed, jellyfish play an important role in the marine ecosystem, being a key component of the gelatinous zooplankton and of the marine food web, but are not represented in routine ecotoxicology. In this study, ephyrae were exposed to several concentrations (0, 0.1, 0.5, 1, 5, 10, 50 mg l -1 ) of eserine (ES) and chlorpyrifos (CPF), a carbamate and an organophosphorous compound, respectively, in order to analyze their toxic effect on this model organism. Acute (% of immobility) and behavioral (% alteration of frequency of pulsations) end-points were investigated after 24 and 48 h of exposure. Exposure to both compounds caused a dosedependent effect, and for each end-point, it was possible to quantify these effects by means of EC 50 . Results highlighted how these compounds reported a high toxicity for marine organisms and exerted their toxic effect on this innovative biological model (in particular, CPF resulted to be more toxic than ES), which proved to be more sensitive than other marine invertebrates commonly used for ecotoxicological bioassays.

“…As "slow species", we have chosen Diplolaimella dievengatensis ) that has a relatively longer generation time and lower fecundity (Table 1). Despite females of both species have similar body length at egg production; L. marina continues to grow after maturation whereas D. dievengatensis does not (Table 1) The SDS detergent, herein utilized as the chemical stressor, is often used in ecotoxicological tests as a reference substance (Jorge & Moreira, 2005;Mariani et al, 2006;Faimali et al, 2014). It has received special attention in the last decades since it is used as a residual of anionic tensoactive agent for household, agricultural and industrial purposes (Singh et al, 2007) and has proved to have detrimental effects on the biota (Messina et al, 2014).…”

Pesticides are a major contaminant in coastal waters and can cause adverse effects in marine invertebrates such as jellyfish. Most studies have investigated short‐term responses of organisms to unrealistically high concentrations of pesticides; however, chronic exposure to persistent low concentrations, which are more likely to occur in the environment, are rarely analyzed. We tested the response of polyps of the moon jellyfish Aurelia aurita to environmental concentrations of the herbicide atrazine and the insecticide chlorpyrifos, individually and in combination, over 9 wk. We hypothesized that exposure to individual pesticides would reduce rates of asexual reproduction and alter polyps' metabolite profiles, and that the results would be more severe when polyps were exposed to the combined pesticides. Polyps survived and reproduced (through budding) in all treatments, and no differences among treatments were observed. Proton nuclear magnetic resonance spectroscopy revealed no difference in profiles of polar metabolites of polyps exposed to the individual or combined pesticides. Our results suggest that A. aurita polyps are unaffected by chronic exposure to atrazine and chlorpyrifos at concentrations recommended as being protective by current Australian water quality guidelines.
