Abstract

IT has been shown1 that the male lugworm (Arenicola marina, L.) can be induced to spawn by injecting into the body-cavity the lipid fraction of tissue extracts of whole worms. It was suggested that release of lipid into the body cavity might provide the immediate (internal) stimulus for spawning under natural conditions. The validity of this suggestion can only be tested when the mechanism by which the gametes are emitted is thoroughly understood.
