The longest-lived species of freshwater bivalve mollusc is the freshwater pearl mussel Margaritifera margaritifera. In 2000, Russian malacologist Dr Valeriy Zyuganov determined the maximum lifespan of this endangered Holarctic species to be 210–250 years, a remarkable discovery verified independently in 2008 by a team of malacological researchers in Finland.
