Fine Structure of the Gametes in Rhynchospio glandulosa (Annelida: Spionidae), a Hermaphrodite Brooding Larvae on the Parent’s Dorsum

Rhynchospio glandulosa is a common polychaete living in silty tubes in soft sediments in temperate shallow waters in the Northwest Pacific. Worms are simultaneous hermaphrodites.
