What are osmoinformers?

Osmoinformers are organisms that can detect changes in osmotic pressure in their environment, allowing them to adjust their internal osmotic balance accordingly. They typically do not actively regulate their internal osmotic concentration but instead, their physiological state reflects that of their surroundings. This strategy is commonly observed in many marine invertebrates, which maintain an osmotic equilibrium with seawater. Osmoinformers play a crucial role in understanding how organisms adapt to varying salinity levels in aquatic ecosystems.
