The swim bladder is the structure that allows a fish to remain both neutrally buoyant and laterally stable (upright). It is a bladder that is inflated with gas to offset the negative buoyancy of the weight of the fish.

Do humans have swim bladder?

All fish have swim bladders. The bladder is what enables them to maintain buoyancy in the water. Without it, they would have to constantly swim up, much like birds have to fly up in the air. It is too much work to constantly swim up, so using a swim bladder, fish do not have to exert as much effort, and preserve energy.

Why does a fish have neutral buoyancy?

A fish has neutral buoyancy to maintain its position in the water column without sinking or floating to the surface. This allows the fish to conserve energy by not having to constantly swim to stay at a certain depth. By adjusting its swim bladder or other internal gas pockets, a fish can achieve neutral buoyancy.
