None ! When submerged it holds its breath. When at the surface it breathes air. It doesn't breathe under water.
Yes It Does :)
The respiratory system includes the lungs and you can not live with out them. So if you try to hold your breath under water for more that an hour it won't work, because we live off oxygen; oxygen feeds all our cells and all our body parts to be able to live. No respiratory system no life.
