Abstract

The influence of methanol extracts of Hypnea mu.sr~forn~(Rish odophyceae) and Ulva ,fasciata (Chlorophyceae) on the development and behavioral changes in the rock boring sea urchin larvae Erhinonletra mathaei was evaluated. H. mu.sc~formiesx tract at 0.095 and 0.0095 rnglrnl suppressed the,development of the sea urchin larvae and retained them in the prism stage itself. In the short-term exposure, larvae up to 5-& day were only affected. The extracts of U. fasciata did not influence the larval developmental stages at lower concentrations.
