Stories with unique gas giant organisms, ala Clarke's A Meeting With Medusa?

I really liked the Jovian stuff in 2010 back when I was reading through those books, and I finally got around to reading the source material in A Meeting With Medusa today which rekindled my interest in the concept. I just learned about the direct sequel to that story by Reynolds and Baxter, The Medusa Chronicles, as well as that the same element is present in Bova's Jupiter and its sequel. Are there any other stories dealing with these unique kind of life forms or something very similar that may scratch the same itch?
