Gonochoristic, oviparous, with a lifespan from 5-10 years. The eggs and early larvae develop in the female burrow, but post larvae are capable of migration. Spawning takes place within the burrow and the release of gametes occurs by rhythmic contractions of the body wall. Gametes are released through the nephridia. Sperm is flushed out of the burrow by pumping activity of the male, while oocytes are retained in the horizontal shaft of the female's burrow.
CONSERVATION STATUS Not listed by the IUCN.
