Food isn’t the only thing cockroaches can survive without. Thanks to their low metabolism, oxygen isn’t essential for them either, at least for a little while. Cockroaches can survive without breathing for up to 40 minutes. This is because their tissue stores what it needs to create oxygen for a little while even when not directly breathing in oxygen. On their body they have 10 pairs of respiratory openings that bring in a sufficient amount of oxygen, and have complex breathing patterns that allow them to adjust how much oxygen and water they let out depending on their environment.
