I have no clue if you're serious atau not, but I will answer it. :] With the level of salt that it has in it, no living creature [i.e. fish] can live in the water.
Yeah! It's quite interesting. :] If one tries to swim in the water, the automatically start floating, haha. It has about 33.7% salinity, and for the size of the dead sea that's quite a lot.
