In 1976 Carl Sagan hypothesized that ammonia-based life could evolve in Jupiter's upper atmosphere. Sagan based this hypothesis on the ecology of terrestrial seas which have simple photosynthetic plankton at the top level, fish at lower levels feeding on these creatures, and marine predators which hunt the fish. The Jovian equivalents Sagan hypothesized were "sinkers", "floaters", and "hunters". The "sinkers" would be plankton-like organisms which fall through the atmosphere, existing just long enough that they can reproduce in the time they are kept afloat by convection. The "floaters" would be giant bags of gas functioning along the lines of hot air balloons, using their own metabolism (feeding off sunlight and free molecules) to keep their gas warm. The "hunters" would be almost squid-like creatures, using jets of gas to propel themselves into "floaters" and consume them.

Do anybody has a picture of this life-forms?

This is a repeat question as I liked the answers!

Or other organism (excluding humans) or even a fossil.

I was thinking of what organism you would put on a sign, symbol, flag, stamp, coaster etc. to represent the wildlife of your region.

Specify where you live, of course.
