Crawfish fan their eggs to ensure proper oxygenation and prevent fungal growth. By using their pleopods, or swimming legs, they create water currents that circulate around the eggs, enhancing gas exchange. This behavior is crucial for the survival of the embryos, as it helps maintain a suitable environment for their development. Additionally, fanning can help remove debris that may accumulate around the eggs.
