Fish mucus holds significant importance in their survival out of water. This slimy secretion serves as a crucial protective barrier, aiding in the prevention of dehydration and acting as a defense mechanism against various threats. The mucus layer helps maintain the fish's physiological balance during transitions from aquatic to terrestrial environments. It serves as a shield, reducing the risk of external stressors and supporting the fish's adaptability. Scientific research indicates that understanding the role of fish mucus contributes to a more comprehensive grasp of their survival strategies. This knowledge is vital for aquarium practices, emphasizing the need to recreate conditions that respect and utilize the protective function of fish mucus.
