These conniwinks form groups in crevices and rock depressions. Two related species live underwater in sheltered areas on mud and sand. They are grazers, feeding on algae. Females lay small ovoid jelly masses, which they attach to sheltered areas, such as the underside of rocks. There are up to 200 eggs in each mass, from which larvae hatch into the plankton before settling and undergoing metamorphosis after an unknown time.


Southern mainland Australia and Tasmania.
