Monkey Napoleon According to a highly speculative "science" program I watched where they posit what alien life might exist in our solar system, the clouds are populated by animals that are a cross between a blimp and a jellyfish.
Rodents of Unusual Size Arthur C. Clarke came up with that idea a long time ago. I would love to visit gas animals just to see if they propel themselves by making fart noises.
infinite zest Didn't Clarke say that we weren't supposed to go there but we can go anywhere else?
It's funny, in college I took this weird class on Dinosaurs for my science requirement, and our final paper was to "evolve" a species on some planet that was a lot like Jupiter from aquatic life to flight. I just said that the flying bird things had developed positive magnetic ions that they got somehow that interacted with the planet's magnetic fields, so they just kind of flew around up there in the sky and couldn't come down and I got an C-. :(
That was Europa. I believe he said "Europa is a baaad bitch, don't even go thinkin' bout fuckin' wit Europa."
memedumpster In 2061 there was also chainsaw sharks that flew around Jupiter sawing up and eating the gas whales. That and the beaked whale that died after eating the spaceship on Europa are the only parts from that book I remember really.
My favorite Jupiter sci fi pulpiness is in Cities in Flight where human engineers wire their nervous systems into remote virtual reality robots and build giant ice bridges in Jupiter's atmosphere. Too cool.
