The species of aquatic invertebrate most tolerant to changes in pH is often considered to be the freshwater snail, specifically Physa acuta. This species can thrive in a wide range of pH levels, demonstrating resilience to both acidic and alkaline conditions. Their adaptability makes them a common subject of studies on aquatic ecosystems and environmental changes. Other tolerant species may include certain types of copepods and amphipods, but Physa acuta is frequently highlighted for its broad tolerance.
