👉 Microperla is a type of microorganism found in the digestive system of some animals, primarily in humans and pigs. It is characterized by its small size, typically less than 0.1 millimeters (μm), but it has a unique adaptation that allows it to survive without oxygen for prolonged periods. Microperlas are not commonly encountered in the environment, making them highly specialized organisms with their own metabolic processes and adaptations.
