Species distribution

5m to deep water. The species occurs in Patagonia, Kerguelen Island and throughout west Antarctica. Two other Antarctic species occur in southern polar waters, L. hosteensis and L. watersi. Further Lacerna species occur in the Subantarctic.

This species is uncommon on boulder undersurfaces but quite common on other organisms such as ascidians, other bryozoans (particularly I. tenuis), brachiopods, or molluscs. Little is known about its ecology. It is a suspension feeder, eating phytoplankton during spring and summer months. It is probably grazed by limpets and echinoids.
