After a three-year investigation into two organised crime groups in Italy’s Campania region that included wire taps, surveillance and nearly 100 suspects, police cracked down with a dozen arrests in March – not for offences linked to drugs or prostitution, but for the illegal harvesting of a small mollusc.
Known as date mussels,
Lithophaga lithophaga are cigar-shaped shellfish that make their homes inside limestone, secreting an acid that slowly carves out a tunnel in the rock. They take decades to grow – anywhere from 18 to 36 years to reach just 5cm in length – and can live for more than 50 years.
