What happens to animals that are deprived of oxygen

Answers

Like humans, if an animal that needs oxygen to survive (almost every living organism) doesn't absorb enough oxygen from its environment, the organism will start to die because their cells need oxygen in order to survive. Animals use oxygen for respiration (breathing), so without it, they will not be able to supply their blood with the oxygen in order to function. 
What will happen to the animal is they will soffocate and die of lack of no oxygen traveling through bones.
