👉 Tail fluid, also known as caudal fluid, is a specialized secretion produced by the tail of certain aquatic vertebrates, particularly fish. This fluid serves multiple purposes, including lubricating the tail fin for efficient swimming, reducing friction between the tail and the surrounding water, and aiding in buoyancy control. Additionally, it can play a role in communication and camouflage by altering the tail's appearance to blend with the environment or signal to other members of the species. The composition and function of tail fluid can vary among different species, reflecting their unique ecological niches and swimming styles.
