👉 Finfluid, also known as finfish or swim bladder fluid, is a specialized bodily fluid found in the gills of bony fish and some other aquatic vertebrates. This fluid plays a crucial role in buoyancy control, allowing fish to maintain their position in the water column without expending excessive energy. By adjusting the volume of finfluid within their swim bladders, fish can either increase or decrease their overall density, enabling them to ascend or descend efficiently. This adaptation is vital for energy conservation and survival in diverse aquatic environments, facilitating activities like feeding, predator avoidance, and reproduction.
