Most animals need oxygen to survive, making it seem impossible for any creature to remain alive when oxygen disappears. Yet nature has produced some remarkable exceptions. One tiny animal is especially famous for its ability to survive conditions that would be fatal to most other animals.
The surprising answer is the naked mole-rat, a mammal that can survive for extended periods in extremely low-oxygen environments and tolerate complete oxygen deprivation for a limited time.
Which Animal Can Live Without Oxygen?
The naked mole-rat is one of the most extraordinary mammals when it comes to surviving low-oxygen conditions. These small, nearly hairless rodents spend their lives in underground colonies where oxygen can become scarce and carbon dioxide can build up.
