The calcified green alga Neomeris annulata manufactures a range of brominated sesquiterpenes (Structures 2.44-2.46), which are concentrated in the fleshy tips of this alga91 and which are individually deterrent to parrotfishes and the sea urchin. However, a mixture of the three metabolites did not increase deterrence, implying that other ecological roles may apply to these metabolites.92...

These sixbrominated sesquiterpenes have been isolated from the Dasydadale Neomeris annulata (Barnekow a al, 1989). 

About 15 meromonoterpenes - aU brominated - were isolated from two calcified species of the Caribbean Cymopolia barbata and Neomeris annulata. Cymobarbatol and 4-isocymobarbatol have antimutagenic properties (Gerwick, 1997).
