Like us, animals depend on oxygen to survive, but there are a few that have evolved extraordinary ways to survive when the flow of oxygen stops. Some of these animals have developed survival strategies that allow them to stay alive with minimal or no oxygen consumption by slowing down their metabolism.
From microscopic creatures to invertebrates, insects, and even a mammal, in this gallery you'll find a list of animals that can live without oxygen for long periods of time. Click on to get to know them.
