On my world sulphur dioxide makes up most of the atmosphere (42%). It comes from constantly active land-based and Hydrothermal vents. I know there are basic, or basic compared to a human, organisms that can 'breathe' sulphur dioxide. Would it be possible for a sentient and relatively large creature to breathe sulphur dioxide?

So my question is:

• Is it possible for my organism to breathe sulphur dioxide?

Sorry if this has been asked before, I searched this site and other sites but I found little that could help. Thank you in advance.
