Plastic contamination in the decapod crustacean Nephrops norvegicus (Linnaeus, 1758)

► Clyde Sea Nephrops norvegicus were examined for the presence of plastics. ► Eighty three percent of the animals sampled contained plastic filaments. ► Tangled balls of filaments were found in 62% of the animals studied. ► Plastic filaments could be sourced to fishing waste. ► Nephrops in the laboratory ingested filaments in their diet.
