👉 A sporozoan is a type of bacterium that has a unique adaptation to live in very acidic environments. Unlike most bacteria, which can survive in a wide range of pH levels, sporozoans are strictly acid-fast and thrive only in the presence of pH 2-6, with the pH slightly higher at the ends of their cell walls. This adaptation allows them to efficiently colonize acidic habitats such as soil or seawater. Sporozoans are often found in marine environments,
