you need oxygen to survive anywhere.. most definately on saturn!!
Provided your conditions are correct for raising Yabbies they should survive and grow. They need at least 1 gallon of water per inch of fish (yabbies are classed as fish) every container needs a cycled filter running 24/7 and they need at least 50% of their water changed every week. They need to be fed several times daily. Good luck with them.
We need oxygen to survive ;D

Every living creature needs oxygen to survive. Just as every living creature needs water to survive. For example, such as spiders. Yup, spiders do to need oxygen AND water to survive, and of course food. So the answer to your question would be yes, snails do need oxygen to survive.
If they CAN survive without oxygen, they are called facultative anaerobes. In other words, these can survive with or without oxygen.If they CAN ONLY survive if there is no oxygen, they are callled obligate anaerobes. In other words, these can only survive if there is no oxygen.
food, oxygen, and water to survive.
No. There is not such thing as too much oxygen just too much carbon. It is good to have a lot of oxygen so the fish dont die because of no oxygen.
