Hyriidae

Hyriidae is a taxonomic family of pearly freshwater mussels, aquatic bivalve molluscs in the order Unionida. This family is native to South America, Australia, New Zealand and New Guinea.[1] Like all members of that order, they go through a larval stage that is parasitic on fish (see glochidium).
