Where seen? This odd seaweed is sometimes seen on some of our Southern shores, in small clumps of a few blades, attached to coral rubble near reefs.

Features: Cluster of a few circular blades about 5-8cm across, smooth and unperforated at the base, a lacy lattice-like mesh at the outer edges which are often ruffled. Sometimes, with little balls attached to the lacy surface. Colours beige or bright green with tinges of lilac or blue.
