Lipophilic extracts from the coralline alga Corallina pilulifera which induced settlement and metamorphosis of fully developed 8-armed larvae of Pseudocentrotus depressus and Anthocidaris crassispina, were found by a simple bioassay method. Benzene, ether, and methanol extracts from the alga also had an inducing effect. Column chromatography showed that simple lipids such as hydrocarbons, triglycerides, and free fatty acids were the inducers. Glycolipid and phos-pholipid did not induce settlement or metamorphosis.
