The marine sponges Dysidea herbacea, D. chlorea and Phyllospongia foliascens were differentiated with difficulty in the field.D. herbacea contained 2-(2',4'-dibromophenoxy)-3,4,5-tribromophenol (1), 2-(2',4'-dibromophenoxy)-4,5,6-tribromophenol (2) and 2-(2',4'-dibromophenoxy)-3,5-dibromophenol (6).D. chlorea contained only 2-(2',4'-dibromophenoxy)-4.6-dibromophenol (3), a compound previously reported as a metabolite of D. herbacea.Phyllospongia foliascens contained 2-(3',5'-dibromo-2'-methoxy-phenoxy)-3,5-dibromoanisole (7) and a 1:2 mixture of 2-(3',5'-dibromo-2'-hydroxyphenoxy)-3,5,6-tribromophenol (8) and 2-(3',5'-dibromo-2'-hydroxy phenoxy)-3,4,5,6-tetrabromophenol (9).
