<P id=p-3>Not all potential invaders lurk inside cargo ships. Many live in plain
sight, clinging to vessels' outer hulls. From mussels to barnacles to algae,
studies suggest that such "hull-fouling" organisms could pose an invasion threat
that is as great as if not greater than that from ballast creatures, researchers
say. So far, however, regulators haven't addressed the hull-fouling issue, in
part because it's not clear how boats can effectively get rid of their clinging
hitchhikers. Researchers are also still trying to understand which hull
organisms can withstand long sea journeys that are fraught with extreme swings
in temperatures and salinities. </P></DIV></DIV></FONT></BODY></HTML>
