PLASTIC FOUND IN JELLYFISH FIND ITS WAY THROUG FOOD WEB

Plastic debris interacting with marine organism is sadly not a new thing, in fact, researchers believe there is no animal free of this problem. Found in large marine mammals, to small zooplancton, even in larvaceans. Marine pollution expands through the animal kingdom. Thus invertebrates represent the most plentiful component of marine biodiversity. To date, plastic ingestion has been documented for 233 marine vertebrates, however, this list could increase as more research is done.

Now, researchers report for the first time the presence of macroplastic debris in a jellyfish species. Recorded during the Mediterranean campaign of the “AQUATILIS EXPEDITION” on Ponza Island, in the Tyrrhenian Sea, mauve stingers were found along with floating anthropogenic litter of different size, colour, shape and type. No similar observations have been reported so far for jellyfish, although their blooms have been observed in regions of plastic accumulation.

- A swimming mauve stinger (Pelagia noctiluca) observed with a plastic lace of a famous cigarette brand among the oral lobes.

Plastic ingestion is associated with both physical damages such as gut blockage, reduced energy reserves and starvation, and potential toxicity due to persistent, bioaccumulative and toxic substances adsorbed onto the plastic surface .Thus, plastic debris provides a pathway for these chemicals to enter marine ecosystems through plastic ingestion.

With this first approach, researchers believe that jellyfish could act as vector of plastics along marine trophic webs, raising further concern on the impact of plastics on marine organisms. Further studies are urgently needed to understand any potential effect for this species and the real extent of trophic transfer of plastic debris.
