Could there be a possibility that there could be fish swimming in Jupiter's moon Europa?

Question

The possibility of fish swimming is very slim. Should this be considered?

There can be underwater volcanic activity on Europa just as Earth does. Bacterial life is possible in Europa.

Answer 1

its possible the earths core is made up of creamed blue cheese

Answer 2

There could be fish...never know.

And there is underwater volcanic activity on Europa.  Hope this helps

Answer 3

If there is anything alive down there below the crusty ice surface of Europa, then whatever they are they will likely look like fish - or at least some of them will.

Mammals and fish in Earth's oceans have displayed convergent evolutions, so it would only be natural for oceanic environments all over the universe to point any life in a similar direction.

Crustaceans would also be a possibility...

Answer 4

Not fish specifically, but a fish like species might exist there. Since fish and aquatic mammals and pas reptiles all took on similar forms it can be assumed that the form of fish is one of the most efficient means of aquatic life and would therefore occur wherever life exists in water.

However, all mammals, reptiles, and fish have a common ancestor which first developed a spine. If this one creature had not evolved than there would have been no fish form on Earth and crustaceans and jellyfish would rule the seas. This puts a big damper on the possibility of fish like species existing on Europa as the chances of it developing what has only occured once on Earth are slim.

That plus Europa's oceans would be very different from Earth oceans. There will be no light and nearly freezing temperatures everywhere except near the volcanic rock at the bottom. That means no eyes and no need to swim far away from the bottom. Plenty of fish fill this kind of niche at the bottom of Earth's Oceans but there will be very few niches on Europa and therefore little diversity making the possibility of fish remote.

Answer 5

The possibility of something swimming in the seas under the ice of Europa is not that far fetched. If microbial life can live on the sulphurous chemicals spewing out of volcanic outlets in the deepest trenches of the oceans on Earth, there is no good reason why something may not have evolved in the waters of Europa.

Evolution is a powerful force driving life into surviving and expanding on available resources and achieving genetic supremacy over previous generations.

Indeed, most of Earth's living history has involved the biochemical evolution of single-celled organisms. Fossilized microbes have been found in rocks as much as three-and-a-half billion years old, and multicellular fossils in rocks a billion years old.

Whatever possibility there is for amino acids to string together to form polypeptides and develop the sophisticated strings of RNA and DNA, they will do it. And Europa has been there for as many billions of years as the Earth has...
