Do Hollows Need To Breathe?

I mean...ok, they´re monsters...but they were people....does hollow need to breath? I dunno....help me please...:)I need some awesome idea about this...

I didn't see hollows are breathing and I think they don't need cause they are just spirits without high reiatsu...hmm I don't know :)

I would imagine that Hollows like shinigami, don't actually breathe, as we understand it. What I mean is it is more of a simulated type environment, like the Matrix.

The "Air" Shinigami and hollows breathe is really just something else made up of spirit particles like everything in the ethreal world of bleach.

I think that tey breath but if they were in the room in which wasnt any oxygen.They dont have to breath :D:D

Good thought, i'm not sure whether they breath or not at all.

But i think they do, if they bleed and get hurt and interact with each other yada yada yada, maybe they breath too.

one thing to do to make sure, a hollow swimming contest @.@

I don't think they need to breathe.

They have holes on their body, so the oxygen enters directly on their hollow lungs. XD

LOL, thats a good thought though.

but i still think there should be a hollow breathing contest, first one to breath wins XD

LOL. That contest will probably go on forever.

hmmm I don't think they breathe.. I've never even seen an Espada pant or sigh O.o

They aren't really living creatures, they basically live like shinigami in a world rich in spirit energy and spirit particles. Their bodies aren't physical perse so my guess would be no.
