Main Ref. Ríos, C. and E. Mutschke, 1999
Remarks Found in shallow subtidal benthic communities of two islands in Saldanha Bay (Ref. 78353) and dominated the sessile fauna of Robben Island at depths beyond 17 m (Ref. 78192). Found attached to rocky substrates, associated with holdfasts of juvenile brown algae, and may occasionally reach greater depths; may be found isolated in intertidal or forming large banks in eulittoral (Ref. 87801). It is also found in forests of Macrocystis pyrifera (Ref. 92889).
