An unusual natural product (dotofide, 1), in which the terpenoid skeleton is interrupted by a guanidine moiety was obtained from the marineslugDotopinnatifida. The absolute configuration of compound 1 was deduced by ozonolysis and subsequent CD spectroscopy. D. pinnatifida subsists on the hydrozoan Nemertesia antennina (Cnidaria), which however does not contain dotofide, suggesting that the snail
