Category: Animals > Adaptation
Some remarkable animals, such as the freshwater turtle and certain species of fish, possess an extraordinary ability to survive for extended periods without oxygen. These species can enter a state of suspended animation or metabolic depression, allowing them to withstand low-oxygen environments. For instance, the crucian carp can slow its metabolism dramatically and switch to anaerobic respiration, which allows it to convert stored carbohydrates into energy without relying on oxygen. This adaptation is particularly advantageous in freezing ponds or stagnant waters where oxygen levels can plummet, showcasing the incredible resilience of life in extreme conditions. Such fascinating adaptations highlight the diverse evolutionary strategies animals have developed to thrive in their habitats.
