Tube worms are complex life. They are perhaps 90% of the way to humans on any scale with bacteria on one side and humans on the other.
The rocky parts of Europa is also tidally heated by gravity of Jupiter and the other three big Jovial moons just like its ocean, or like Io. So it is probably geologically active underneath the ocean. We don't know if there is plate tectonics, but we can imagine other forms of active geological activity, such as hot spot volcanism with extensive underwater equivalent of fumerals, which could drive hydrothermal cycles to support tube worm like creatures.
Without plate tectonics the whole thing is useless. You need plays tectonics for a carbon cycle and for tube worms you need a carbon cycle.Also you would need seduction because it is covered with a massiver layer of ice. Meaning that with out tectonics taking short back into the mantle the impurities spouted BT the volcanoes will just build up.
To-morrow, and to-morrow, and to-morrow,
Creeps in this petty pace from day to day,
To the last syllable of recorded time;
And all our yesterdays have lighted fools
The way to dusty death. Out, out, brief candle!
Life's but a walking shadow, a poor player,
That struts and frets his hour upon the stage,
And then is heard no more. It is a tale
Told by an idiot, full of sound and fury,
Signifying nothing.
