“…Immediately after collection, the crabs were transported to the laboratory and frozen. The animals were identified according to Ferreira and Melo (2016), counted and sexed considering pleopod presence, number and location (Ferreira, 2015). Males have only the second pleopod present, which is modified as a gonopod, while females only have the third to fifth pleopods, which are long and setose (Baeza & Asorey, 2012; Ferreira, 2015).…”

“…Pachycheles laevidactylus Ortmann, 1892 mainly inhabits the intertidal zone and can be found under rocks, among seaweed or in mussel beds (Veloso, 1999). They can also live in facultative symbiosis with species of Bryozoa or polychaete sandbanks of Phragmatopoma Mörch, 1863 (Ferreira & Melo, 2016). This species occurs exclusively in the western Atlantic, from the state of Maranhão in northeast Brazil to Monte Hermoso in Argentina (Ferreira & Melo, 2016; Mantelatto et al, 2021).…”

Although it is widely distributed in Brazil, the only population data available are from Argentina: Bremec and Cazzaniga (1984 as P. haigae) reported some biological data of the species, while Camiolo and Luppi (2016) studied its habitat and population structure, heterochely, relative growth, morphological maturity and fecundity.…”

The anomuran family Porcellanidae Haworth, 1825 occurs worldwide in tropical and temperate marine habitats, especially in intertidal and subtidal zones (Ferreira & Melo, 2016;Osawa & McLaughlin, 2010). The family comprises around 30 genera and 280 species described (Bezerra et al., 2019). Most porcelain crab species are free-living and can be found on rocky shores, coral reefs and estuarine areas (Veloso, 1999). Some display symbiotic relationships with other organisms, both free-living such as shrimps, hermit crabs, turtles and fishes (

Assessment of microplastic pollution is a societal concern with negative impacts on fauna and flora. An omnipresence of these pollutants in aquatic, atmospheric, and terrestrial ecosystems was indicated. In a marine environment, the microplastic accumulation and effects were identified in many organisms (annelids, bivalves, crustaceans, fishes, mammals…). Unfortunately, many microplastic (MP) toxicity experiments used commercial particles (mainly polyethylene or polystyrene), which do not illustrate the diversity of environmental MP. We evaluated the effects of environmental MP on Porcellana platycheles, which is a European singular crustacean (Anomura) being a filter-feeder organism. We carried out direct exposures for 5 and 10 days at two environmental concentrations [10°µg/L (low) and 100°µg/L (high)]. The biomarkers analysed were the antioxidative response level, acetylcholinesterase activity, lipid peroxidation, and energy reserves. Our study revealed a high acetylcholinesterase inhibition reflecting neurotoxicity, and modulation of antioxidative responses illustrated successively by an increase of enzymatic activities at 10°µg/L after 5 days, and a decrease after 10 days of exposures. Inhibition of antioxidative activities at 100°µg/L was also noted. We hypothesised that this “inverse U-shaped” enzymatic activity could be due to 1/ the presence of endocrine disruptors associated with MPs, such as Dibutyl phthalate found in high concentration (126°µg/g) in our MP samples and/or 2/ collapse of the endogenous antioxidative enzymes. In parallel, a depression of glycogen was demonstrated during the experiments indicating an energy investment in maintaining homeostasis. Thus, Porcellana platycheles possesses all the criteria to be considered as a potential sentinel species to detect the microplastic effects.
