Marine litter loads are increasing worldwide and impacts and effects on marine ecosystems and their inhabitants are still unknown [1,2]. Whereas interaction effects of macrolitter, especially on species as sea turtles and marine mammals has been more investigated, the microscopic fraction has been less addressed. Therefore, several key species of fish, crustaceans and elasmobranches have been studied to assess microplastics ingestion in the Western Mediterranean. Mean ingested microplastics (MPs) ranged up to 2.3 MPs/ind indicating a threat of this man made contaminant on species which are commercialised
