Asperarca[1] is a genus of bivalves in the family Arcidae[2] which currently consists of eight species. They attach themselves to rocks or hard substrates with byssal threads in shallower, coastal waters. It was first described by Dr. Federico Sacco in December 1898 with the type taxon A. nodulosa that has been recorded throughout the coastal Mediterranean Sea, Baltic Sea, and northeastern Atlantic Ocean.[1] The earliest known species are A. acuta and A. microida which were found in 2014 in Ukraine from the Eocene Epoch.[3]
