Jupiter's atmosphere is a turbulent storm of rising and sinking gasses or clouds.    Gasses, super-heated by Jupiter's intense atmospheric pressure, rise to the upper reaches of the atmosphere.  Winds of super hurricane force move the gasses around in the atmosphere until they cool and sink.  This repeating cycle results in Jupiter looking like a boiling pot of water full of different colored dyes.

What type of special adaptations would a creature have to have in order to live on Jupiter?.
 
 

Most famous of Jupiter's storms is the Giant Red Spot which is estimated to be 300 years old.  Located in Jupiter's southern hemisphere, it is larger than two Earths.  The Giant Red Spot grows and shrinks in size over time.  However, since its first sighting 100 years ago, it has never gone away.  That's one long storm!
