Secondary metabolites in yellow and grey morphs of the soft coral Parerythropodium fulvum fulvum were compared between colonies collected from different depths and reef sites along the Red Sea. The concentrations of fulfulvene, the major metabolite in the yellow morph, varied considerably among samples, with significant differences between shallow and deep colonies. The concentrations of 5-hydroxy-8-methoxy-calamenene and 5-hydroxy- 8-methoxy-calamenene-6-al, the major metabolites in the grey morph, also exhibited significant differences between shallow and deep colonies. The ecological implications of these variations in secondary metabolites are discussed.
