However, there's little on it here, so I've decided to whip up some tips for designing Jovian creatures. The core may or may not be minable.

Gas giants are sometimes known as failed stars because they contain the same basic elements as a star. It could be, but least likely.
The primary composition of Gas Giants are Hydrogen and Helium. A gas giant is a giant planet composed mainly of hydrogen and helium. Yes. I believe gas giants have life.

A gas giant is a large planet composed mostly of gases, such as hydrogen and helium, with a relatively small rocky core.

One of the many problems with such an idea is how life even gets started on this world. Gas giant planets are seas of liquid gases, containing several floating islands made of cloud blocks, which are extremely rich in ores. There is growing evidence of subsurface liquid water on several moons in the Solar System orbiting the gas giants Jupiter, Saturn, Uranus, and Neptune.However, none of these subsurface bodies of water has been confirmed to date. with clouds rich in ammonia and ammonium hydrosulfide.

We know only of Life made of Carbon based compounds. This first thing you must consider is that gas giants have far stronger gravitational pulls than Earth. Carl's early speculations on Jovian atmosphere life in the 1960s had evolved and he eventually worked out the basic hunters, floaters and sinkers ecosystem which he described in a paper with Ed Salpeter: "Particles, Environments, and Possible Ecologies in the Jovian Atmosphere", which appeared in The Astrophysical Journal, Supplement Series in late 1975. Life in the atmosphere of a gas giant has often been fetatured in science fiction. Just below rests a sea of random liquid gas.
Air is only present in the upper layer of the planet.

These gas giants are beautiful.

With limited Carbon, Nitrogen and Oxygen, life can't exist as we know it.

Steven Hawking and Carl Sagan have confirmed the likelihood of 'habitable' gas giants with life, and I've thought of making a gas giant with life on the wiki. Nr 1:Sudarsky Class I gas giants. There are 2 classes of gas giants i believe have life. The core of a gas ball is usually a sea of a random liquid, anything from Lava to Healing Water can be found there. Liquid water is thought by most astrobiologists to be an essential prerequisite for extraterrestrial life.

The gas giants of our solar system are Jupiter, Saturn, Uranus and Neptune.
