Detailed explanation-1: -The swim bladder is located in the body cavity and is derived from an outpocketing of the digestive tube. It contains gas (usually oxygen) and functions as a hydrostatic, or ballast, organ, enabling the fish to maintain its depth without floating upward or sinking.

Detailed explanation-2: -The gas bladder (also called a swim bladder) is a flexible-walled, gas-filled sac located in the dorsal portion of body cavity. It controls the fish’s buoyancy and in some species is important for hearing.

Detailed explanation-3: -The gas that fills the bladder is oxygen, carried by hemoglobin in the blood of the fish. In all animals most of the oxygen in blood is bound to the protein hemoglobin, which is inside the red blood cells. A unique property of the hemoglobin in fish with swim bladders enables the fish to fill or empty its swim bladder.

Detailed explanation-4: -This is a thin-walled sac located inside the body of a fish that is usually filled with gas. Besides helping fishes stay buoyant it can also function as a sound producer and receptor or as an accessory respiratory organ. Wonder how a swim bladder works?

Detailed explanation-5: -The swim bladder is essentially a sac that fills with air. It is used to regulate depth and buoyancy, allowing fish to stay at certain levels without having to use energy on swimming. It has been theorized that the swim bladder is very similar to the lungs, as it shares many of the same characteristics.
