Slug and other gastropods have what's called an open respiratory system. Humans, for comparison, have a closed respiratory system. Essentially, slugs "breathe" through the pours of their skin. Oxygen enters and carbon dioxide exits.
Yes, slugs need oxygen. Most everything living needs it. Even plants and trees need oxygen. They don't "breathe" but, rather, respire - taking in oxygen and getting rid of carbon dioxide. That can be confusing since plants also use photosynthesis during daylight hours to take in carbon dioxide and get rid of oxygen.
However, some bacteria do not - and a new tiny discovery (named Spinoloricus Cinzia) in the Mediterrean does not need it, either.
No, it needs oxygen just like 99.999% of all multicellular organisms.
I deleted the answer because the last person said yes. His reason was because there are underwater snails. To clear that up, all organisms under water absorb oxygen through their gills and into their body.
Anaerobic bacteria can live without oxygen. In fact, oxygen is toxic to many of them.
Archaebacteria called extremeophiles have some species that live entirely anaerobically. Bacteria [and other organisms] that respire using O2 as the 'final' electron acceptor are termed to be Aerobic, while bacteria [and the odd organism] that has the biochemical capacity to Live without O2 are termed to be Anaerobic.
Bacteria that must have oxygen to survive are called obligate aerobes. Some bacteria can live with or without oxygen and are called facultative anaerobes.Anaerobes = No oxygenAerobes = Oxygen
it can live for 2 hours
about 2 to 5 minutes

No. No animal can live without oxygen
yes
Yes
No a snail can't live in a snail.
3 months
Snail do not need company so the death of the fish will not affect it in any way other than to leave more oxygen available for the snail. It will be perfectly OK for several weeks provided the water does not go bad.
No
You cannot live without oxygen for more than 5 minutes. :D
you cant live without oxygen

Yes, there are types of snail that can live underwater.
