    Osmosis: unless the concentration is the same as in your (the fish's) body, osmosis will occur and the cells in your (the fish's) body will either blow up like balloons until they explode or shrivel up.

    Your question is somewhat dependent on what you mean by "marine life", if you are referring to fish and other macrobiotics then yes they typically don't do well in environments with salinity into the +2M range. However search the terms halophile (translated: salt-loving) or halotolerant and you will see that numerous lifeforms have adapted to life under such extreme conditions. You should also be able to find out how these organisms beat the process of osmolysis brought up by russ_watters.
