Abstract: Methods have been developed for observing the effects of DDT on the development of the larval skeleton in the purple sea urchin (Strongylocentrotus purpuratus). These include uptake studies with C14-labeled DDT to determine the amount taken up by the developing embryo, direct observations of skeletal growth, and observations of other facorts which might indicate a general depressing effect of DDT such as rate of cleavqage, time of hatching, and rate of protein synthesis.
