How long can a shark live out of water?
Death will follow between four and six minutes after that. Without oxygen, most large shark species will suffer a very similar fate. Hypoxia will rapidly cause brain damage, so while an oxygen-deprived shark may appear to be still alive, it will likely rapidly suffer irreversible damage in just a few minutes.

Epaulette sharks can survive for over three hours in conditions with less than 5% oxygen without loss of behavioral responsiveness. In laboratory testing these sharks have survived for an hour without oxygen at 30oC, this temperature is far above that at which most hypoxic tolerant organisms are capable.
