Glochidium

Glochidium: specialist larval form in some freshwater bivalves, characterized by a bivalve shell, with or with a pair of hooks, and a long adhesive thread or tentacle. It lives as a temporary parasite on the gills or fins of fish. In some species a modified glochidium is termed a 'lasidium' before attachment and a 'haustorium' after attachment (Stachowitsch, 1992).
