Dear Conch-Lers, does somebody know which species is called 'Sode-gai' in japanese. It is a japanese bivalve which produces or at least is able to produce pearls. Pearl oysters have different names in japanese, so it might be one of the unionids. The name 'Sode-gai' has been used by Von Siebold in one of his diaries. Looking forward to any suggestion Jeroen Goud [log in to unmask]
